Section A: Enhancements
(none)

Section B: Bugs Fixes
1.  The Soft Soil Tire-Terrain Model was calculating the tire
    plough force in the soil, and tire sinkage and plough force 
    were being displayed properly in Key Results and Variable
    Output windows. However, the force was not included in the 
    equations of motion. Thus, the plough force had no effect on 
    vehicle behavior. This has been corrected.

Section C: Other Changes
1.  Environment models shipped with HVE Version 5.1 have incorrect
    soil attributes. As a result, using the soft soil model on an
    asphalt surface of one of these environments will result in 
    sinkage. This problem can be corrected by assigning the 
    correct attributes. To do this, select an environment from
    the list of available environments (e.g., 2T2_Intersection.h3d)
    and perform the following steps:

    1. Launch the 3-D Editor.
    2. Click on the road surface to select it (it will be 
    surrounded by a red bounding box).
    3. Click on Material Edit... in the Object Attributes dialog. 
    The Environment Material Properties dialog will be displayed.
    4. Set the values for Bekker Soil Exponent, Frictional Soil 
    Modulus and Cohesive Soil Modulus all to 0.0.
    5. Press OK.
    6. Repeat steps 2 - 5 for each non-soil surface to be driven 
    on.
    7. Close the 3-d Editor

    The environment is now ready for use.

    NOTE: This issue does not effect existing cases 
          that include these (or any) environments.

===<Part 1: Changes to HVE System Software>=======================

Section A: Enhancements
1.  Vehicle Editor: The maximum tire width has been increased 
    to 20 inches from 16 inches. This allows simulation of vehicles 
    fitted with jumbo tires.
2.  Event Editor: The Options menu now includes a Get Surface Info
    dialog. The dialog contains the Get Surface Info option and 
    a new Search Direction option that allows more general 
    vehicle motion (e.g., a "loop-de-loop"). The Get Surface Info
    option is no longer presented in the Calculation Options 
    dialogs.
3.  Event Editor: Interprocess communication (i.e., the task of
    passing data back and forth between HVE and the current
    physics program) has been completely rewritten. Multi-
    processors and Hyperthreading Technology (HTT) are now 
    supported (you may wish to turn on Hyperthreading if your 
    computer supports it). This also provides direct support for 
    computers using Windows 2000 operating systems.
4.  Event Editor: HVE now includes three new tire-terrain models:
    Radial Spring, Sidewall Impact and Soft Soil. These new models
    are selectable in the Set-up, Wheels dialog.
5.  Vehicle Editor: The Inertias dialog now has "Basic" and 
    "Detailed" options. The first option displays only vehicle 
    total inertias (weight, mass, rotational inertias). The second 
    option also displays unsprung inertias. The dialog also 
    includes a new user-selectable option that updates rotational 
    inertias when weight is changed.
6.  Vehicle Editor: HVE now confirms that the unsprung mass is 
    not zero or negative, thus preventing an instability during a
    vehicle simulation.
7.  Vehicle Editor: The HVE Vehicle Model now includes a robust
    model for steer axis geometry. Steerable wheels no longer
    steer about a vertical axis through the wheel plane. Wheels
    may now be steered about an inclined axis defined by the 
    kingpin geoemtry (Caster and Inclination Angle). This allows 
    for simulating the effects of wheel alignment on vehicle
    handling.
8.  Event/Playback Editors: The Variable Selection dialog includes 
    the following new variables: Tire Group, Radial Deflection, 
    Fx,Fy,Fz Sidewall; Wheel Group, % Available Mu.
9.  Event Editor: The DyMESH Options dialog now includes the 
    ability to set a special default (typically smaller) 
    Trajectory Integration Timestep and Output Time Interval 
    whenever DyMESH is used.
10. Event Editor: The Set-up, Vehicle Mesh dialog now allows the
    user to specify explicitly if a mesh is known to be watertight. 
    Non-watertight meshes may result in rogue vertices and failure
    to sense inter-vehicle contact. Explicitly setting the
    watertight status also allows DyMESH to optimize its 
    calculations (and execute faster).    
11. Event Editor: The Set-up, Vehicle Mesh dialog now includes a
    "Weld Distance" parameter that helps to improve DyMESH 
    results by reducing errors related to poor geometry (adjacent 
    triangles that were intended to share a vertex may not do so
    due to small errors in vertex location). This helps to prevent 
    problems with non-watertight meshes (see preceding enhancement).
12. Event Editor: A Calculation Model can now have a user-defined
    filename (with completely qualified path description) assigned
    in its Calculation Options dialog.
13. Event Editor: If the current physics program is 3-D, the Driver
    Controls options now automatically default to Brake Pedal Force
    and % WOT.
14. Playback Editor: The Report Window Information dialog now 
    includes an Event Status that lets the user know if the 
    selected event has been executed (and, therefore, has output 
    reports available).
15. HVE now performs more robust checking of a file that it is 
    attempting to open or save. This helps to prevent creating 
    corrupt case files as well as crashing while trying to open
    a corrupt or incompatible case file.

Section B: Bugs Fixes
1.  Event/Playback Editors: Vehicle contact surfaces were not 
    selectable from the Variable Selection dialog during 
    occupant/pedestrian simulations. This has been corrected.
2.  Vehicle Editor: User.db files containing vehicles created using 
    different HVE versions caused a problem. The axle/wheel infor-
    mation was not being assigned properly. This has been corrected.
3   Vehicle Editor: Error handling for tires created with incorrect 
    size designations has been improved; more detailed message 
    diagnostics are now presented to the user.
4.  Playback Editor: AVI movie files sometimes skipped frames. This 
    was especially true if anti-aliasing was increased. This has 
    been corrected. All AVI movie files are now produced at 
    30 frames/second.
5.  Vehicle Editor: The Brake Designer dialog now updates the
    Brake Information dialog with the current value for Pushout
    Pressure. 
6.  Event Editor: Collision Pulses were not stored properly for
    pulse types other than Acceleration pulses. Opening a file
    creating one of these pulses caused a crash. This has been 
    corrected.
7.  Event Editor: The Damage Profile dialog's A Stiffness and
    B Stiffness dialogs were range checking fields that were not 
    enabled. If an error was detected, the user could not easily
    edit the errant value. This has been corrected.
8.  Event Editor: The Tessellation Progress window was not always 
    displayed when tessellation occurred. This has been corrected.
9.  Vehicle/Event Editors: Tables did not check for rows with 
    duplicate independent values (e.g., Time). This has been 
    corrected. HVE now displays a message if any table has duplicate
    row entries for the independent (i.e., first column) variable.
10. Event Editor: Case Files that include Target Positions did not
    display the targets if Show Targets was not enabled when the 
    event was initially selected and HVE was not started in Event 
    mode. Targets are now displayed correctly.
11. Event Editor: The Position/Velocity dialog's w-velocity field
    is no longer enabled for 2-D simulations (the value is not
    used).
12. Vehicle Editor: While using SI units, pressing Apply in the 
    Brake Designer dialogs would needlessly alter the value for 
    Pushout Pressure. This has been corrected.
13. While saving a file using Save-As, if Cancel was pressed (i.e., 
    the file was not saved), HVE would then allow the user to exit 
    without checking to see if the file needed to be saved. This 
    has been corrected.
14. Playback Editor: If two collision events were created and one 
    of them included a fixed barrier, certain conditions allowed 
    the user to create a simulation in a Playback Window in which
    the barrier was not displayed. A "Node not found" message 
    was sometimes displayed. This has been corrected.
15. Event Editor: The Collision Pulse dialog did not correctly pull 
    in Force/Moment pulses from other events. This has been 
    corrected.
16. Event Editor: HVE allowed user to perform several operations
    (e.g., File Saving, Exit) while an event was executing. The
    result was unpredictable. HVE now disables numerous parts of
    the user interface while an event is executing. See also 
    Enhancements, Interprocess Communication (above).
17. Vehicle Editor: Proportioning Valve, Pstart value was not 
    correctly stored if SI units were used. This has been corrected.
18. Vehicle Editor: The Apply button in the Drivetrain dialog was
    partially covered by another part of the UI. This has been 
    corrected.
19. Event Editor: Vehicle body or axle position with respect to the 
    terrain was incorrect after adding a payload or moving the CG
    and then saving and re-opening the case file. This has been 
    corrected.
20. Event Editor: If the payload dialog was displayed at the end of 
    a simulation, pressing OK caused the vehicle(s) to be 
    redisplayed at their initial positions. This has been corrected.
    The vehicles are only returned to their initial position if
    Reset or Rewind is pressed.
21. Event Editor: If the CG of a Generic Vehicle was moved (using 
    Move CG), the damage profile was not correctly displayed.
    This problem was not normally apparent unless the vehicle was
    highly tessellated. This problem has been corrected.
22. Event Editor: Some fields in the DyMESH options dialog lost 
    their formatting when the dialog was OK'd and redisplayed. 
    This has been corrected.
23. Environment Editor: The Sky Attributes Ambient Light Intensity
    field disappeared if the value was changed using the slider.
    This has been corrected.
24. Event Editor: A certain condition sometimes lead to a crash 
    while selecting a vehicle by clicking on it in the viewer. 
    This condition has been corrected.
25. Event Editor: Numerous re-executions sometimes caused a crash
    if a vehicle included wheel image textures. This condition
    has been corrected.
26. Event Editor: While using the Set-up, Wheels, Brake option, 
    pressing OK resulted in a long time delay for HVE systems
    that used an EDKEY. This has been corrected.
27. Playback Editor: The Variable Output table contained an
    interpolation error that resulted in a rounding error between
    Playback Time Intervals. This condition has been corrected.
28. Event Editor: Key Results windows for Reconstruction-type 
    physics programs did not clear when Reset was pressed. This
    has been corrected.
29. Event Editor: The Set-up, Wheels Brakes dialog would store
    an edited value even if Cancel was pressed afterwards. This
    has been corrected.
30. Environment Editor: The default ambient pressure was 
    incorrectly set to 29.91 in Hg. It is now set to 29.92.
31. Event Editor: If the user set up a reconstruction-type event
    with one vehicle, then set up a second reconstruction-type 
    event with another different vehicle and then displayed the
    Units dialog, pressing OK caused a message "Node not found 
    in list" to be displayed and Key Results windows displayed
    zero values. This has been corrected.
32. Environment Editor: If the user attempted to open an 
    Environment Materials file containing bad properties, an
    error message was displayed, but the file would be opened and
    the errant data would be displayed and accepted. The 
    Environment Materials dialog no longer accepts errant data.
33. Event Editor: If Key Results windows were displayed and the 
    user changed to a monitor with lower resolution, the Key
    Results windows would sometimes be lost off the right edge or
    bottom of the display. These windows are now placed in the 
    upper left corner of the desktop so the user can gain access 
    and reposition them.
34. While saving a case file, if the user cancelled the 
    "Over-write an existing file?" message, then exited HVE, the
    existing file would be over-written without asking the user. 
    This has been corrected.
35. 3-D Editor: The Light Editor Tool contained incorrect default
    values, sometimes causing a crash. This has been corrected.

Section C: Other Changes
1.  Event Editor: The Collision Pulse dialog has been redesigned
    and is much more robust.
2.  Vehicle/Event Editors: The maximum table length Collision 
    Pulse tables was hard-coded to 5000 rows. Table length is 
    now dynamically allocated for all tables. This allows 
    Collision Pulse tables to be of any length. The possibility of 
    HVE crashing while trying to import a collision pulse with more 
    than 5000 rows of data has been eliminated.
3.  Playback Editor: HVE now displays a message if for any reason 
    it was unable to create an AVI movie file.
4.  Playback Editor: AVI movies are now created using an 
    "off-screen renderer." This eliminates the potential for the 
    cursor or screen-saver being displayed in a movie.
5.  All Editors: Material files may now have comments (a line 
    beginning with '#').
6.  Environment Editor: All Environment Material files now have 
    Bekker Soil Constants and include comments regarding the 
    source of the data.
7.  Vehicle Editor: The Error range for Lateral Spring Spacing 
    has been increased to 80 inches from 60 inches. (The Class 2
    (Utility) trailer has a lateral spring spacing of 73 inches.)
8.  Event Editor: The Driver Controls Gear Table no longer uses
    a user-editable drop-down list (editing the available options
    was irrelevant anyway).
9.  Event Editor: The format for Brake Initial Stroke and Temperatures
    (Set-up, Wheels, Brake dialog) has been change to f7.3 and f7.1,
    respectively. All were previously f7.2.
10. Event Editor: The Driver Controls, Path Follower option has been 
    renamed HVE Driver.
11. Event Editor: The Position/Velocity dialog now automatically 
    recalculates the forward and lateral velocity components if the 
    vertical velocity component is changed. 
12. A SupportData folder has been added beneath the calcMethods 
    directory. This folder is generally used by physics programs
    that require specific input from a user-named file, or write 
    output data to a user-named file.
13. Playback Editor: The Report Window Information dialog remembers 
    which event was selected the last time the dialog was displayed
    (this simply streamlines user interaction).
14. Event Editor: The Event Window Information dialog remembers which
    Calculation Method was selected the last time the dialog was 
    displayed (this simply streamlines user interaction).
15. Playback Editor: The Audit Trail Preview Window number was 
    zero-based. This has been 'humanized' by making it 1-based.
16. Event Editor: The Vehicle Name is now displayed in the title 
    bar of the Set-up, Belt Restraints dialog.
17. File Saving is no longer disabled if the file is unchanged 
    since the last Save.
18. Event Editor: The Set-up, Wheels, Blowout, Rolling Resistance
    multiplier is now disabled while running 2-D simulations.
19. When the user opens a case file, HVE now checks the version 
    number of the case file and compares it to the user's HVE 
    version. If the case file is from a newer version of HVE, HVE 
    will display a warning message and abort the attempt to open 
    the file.
20. Vehicle Editor: The ranges for Tire Initial and Secondary
    Riderates were changed to be consistent with each other, and
    to allow for large truck tires (Jumbos).
21. Vehicle Editor: The maximum range for Tire Rolling Resistance 
    was incorrectly set at 30.0. It has been changed to 1.0.
22. Event Editor: The method for creating Generic Vehicle geometry
    has been modified so that it creates a watertight mesh.
23. Event Editor: The positioning of trailers has been improved;
    the tires are now in setting on the terrain under most 
    conditions (non-planar terrains are not rigorously supported
    during vehicle positioning because suspension/tire deflection
    is not included).


===<Part 2: Changes to SIMON Software>=======================

Section A: Enhancements
1.  SIMON now incorporates the HVE Steer Geometry model. This model
    includes Caster, Camber, Kingpin Inclination and Steer Offset.

	NOTE: The inclusion of steering geometry may cause 
              small differences in results between this and 
              previous SIMON versions. To eliminate this effect,
              set the Caster Angle, Kingpin Inclination Angle and
              Steering Offset to zero.

2.  SIMON now uses HVE's new Radial Spring, Sidewall Impact and 
    Soft Soil Tire-Terrain Models (see HVE Enhancements, above).
    Tire Sidewall Fx, Fy, Fz  and Tire Fx, Fy Plow Forces (for
    soft soils) have been added to the Variable Output, 
    Tire group.
3.  SIMON now displays Steering System Information for each 
    steerable axle in the Vehicle Data Report. Previously, data for
    only one steerable axle were reported.
4.  SIMON now allows the user to assign the Collision Acceleration
    Threshold (see SIMON's Calculation Options dialog). Previous 
    versions had the value set internally to 1.0 g.

	NOTE: Setting the value to 1 g sometimes caused an
	      error on the calculation of separation velocity:
	      If the acceleration exceeded 1 g due to post-impact
	      load transfer, the collision interval was
	      extended and the resulting delta-V was higher.
	      This error would be observed in the Accident History 
   	      and Damage Data output reports.

5.  Tire Radial Deflection has been added to the Variable Output, 
    Tire group.
6.  SIMON now supports the HVE Brake Failure Model (Set-up, Wheels, 
    Brake).

Section B: Bug Fixes
1.  The Vehicle Data Report incorrectly displayed -999.9 for the
    A-Stiffness and B-Stiffness values. The report now includes a 
    table of A- and B-Stiffness values for each surface of the 
    vehicle.
2.  The Vehicle Data Report incorrectly displayed Vehicle
    Overall Height and Ground Clearance for vehicles with 
    payloads not located a the CG. This has been corrected.
3.  The brake temperature calculation method was using the 
    temperature of the lining. The expansion coefficient was
    using the temperature of the drum. Drum temperature is
    now used in both places. 

	NOTE: This change may cause small differences
	      in results between this and previous versions.
	      The effect occurs only for simulations
	      involving S-Cam and Wedge Air Brakes.

4.  The initial wheel coordinates were used for axle roll
    torque calculations, instead of the current value (which 
    may be different from the initial value, depending on axle
    roll angle). This has been corrected.

	NOTE: This change may cause small differences
	      in results between this and previous versions.
	      The effect occurs only for simulations
	      involving vehicles with solid axle suspensions.

5.  Tire velocity is now calculated at the center of the tire 
    plane. Previous versions calculated tire velocity at the 
    center of the wheel plane. Thus, tire contact patch 
    velocities will be slightly different for vehicles with 
    dual tires.

	NOTE: This change may cause small differences
	      in results between this and previous versions.
	      The effect occurs only for simulations
	      involving vehicles with dual tires.

6.  Tire velocity components were incorrectly calculated in
    the previous version of SIMON. The effect is normally
    very small.
 
	NOTE: This change may cause small differences
	      in results between this and previous versions.

7.  The sign of wheel camber angle was incorrect for vehicles 
    with solid axle suspensions. This has been corrected.

	NOTE: This change may cause small differences
	      in results between this and previous versions.
	      The effect occurs only for simulations
	      involving vehicles with solid axle suspension
              with non-zero wheel camber (quite rare).

8.  SIMON was not listening to an error return from its tire model.
    An error return from the tire model now results in event 
    termination and an error message.
9.  SIMON was not assigning the current value of peak friction 
    for the % Available Mu Brake and Throttle Table Methods. Thus,
    these methods did not work. This has been corrected.

	NOTE: EDC strongly recommends the Brake Pedal Force 
              % WOT methods, not the % Available Mu methods.


Section C: Other Changes
1.  The Get Surface Information option is no longer displayed 
    in the SIMON Calculation Options dialog. It has been moved
    to HVE's Options Menu.
2.  The threshold value for Maximum Suspension Force termination
    is now dynamically assigned according to vehicle mass. In 
    previous versions, it was set to 50,000 lb for all vehicles,
    regardless of weight. This sometimes caused unnecessary 
    event termination for heavy vehicle simulations.
3.  SIMON now assumes the data from the Wheel Damage, Camber
    Displacement dialog is now consistent with other Camber 
    references in HVE (top of tire tilted outward is + camber, 
    regardless of right or left side). 

	NOTE: This change may cause large differences
	      in results between this and previous versions.
	      The effect occurs only for simulations
	      involving vehicles damage-displaced wheels.

4.  The previous version of SIMON reported only a limited 
    number the of DyMESH options in the Program Data Report.
    SIMON now reports all of the DyMESH options.
    

===<Part 3: Changes to DyMESH Software>=======================

Section A: Enhancements
1.  DyMESH now provide an explicit calculation method for
    collision simulations using a non-watertight mesh. DyMESH
    also will determine the condition of the mesh (watertight vs.
    non-watertight), if requested.

Section B: Bug Fixes
1.  A DyMESH error returned during initialization (i.e., the
    start of a DyMESH run) caused HVE to crash. This has been
    corrected.

Section C: Other Changes
1.  DyMESH now allows meshes that have up to 80 polygons sharing
    a single vertex. The previous version was limited to 40.
    This increase allows DyMESH to simulate collisions involving 
    more complex meshes.


===<Part 4: Changes to EDSVS Software>=======================

Section A: Enhancements
(none)

Section B: Bug Fixes
1.  EDSVS was not correctly calculating peak and slide friction
    coefficients for a tire traveling across multiple friction 
    zones. This has been corrected.

Section C: Other Changes
1.  The Get Surface Information option is no longer displayed 
    in the EDSVS Calculation Options dialog. It has been moved
    to HVE's Options Menu.


===<Part 5: Changes to EDVTS Software>=======================

Section A: Enhancements
(none)

Section B: Bug Fixes
(none)

Section C: Other Changes
1.  The Get Surface Information option is no longer displayed 
    in the EDVTS Calculation Options dialog. It has been moved
    to HVE's Options Menu.


===<Part 6: Changes to EDCRASH Software>=======================

Section A: Enhancements
(none)

Section B: Bug Fixes
1.  EDCRASH incorrectly calculated closing velocity and coefficient 
    of restitution for some types of collinear collisions (if both
    vehicles have positive forward velocity components). This has
    been corrected.

	NOTE: This problem did not affect the calculation of
	      vehicle impact velocity, separation velocity
	      or delta-V.

Section C: Other Changes
(none)

===<Part 7: Changes to EDSMAC4 Software>=======================

Section A: Enhancements
1.  EDSMAC4 now supports the HVE Driver Model. This model calculates
    the steering inputs required to negotiate a user-defined path.
2.  EDSMAC4 now allows the user to assign the Collision Acceleration
    Threshold (see EDSMAC4's Calculation Options dialog). Previous 
    versions had the value set internally to 1.0 g.

	NOTE: Setting the value to 1 g sometimes caused an
	      error on the calculation of separation velocity:
	      If the acceleration exceeded 1 g due to post-impact
	      load transfer, the collision interval was
	      extended and the resulting delta-V was higher.

Section B: Bug Fixes
1.  The damage profile sometimes failed to include the entire
    damage range. This has been corrected.

	NOTE: The new method may require a smaller output time
	      interval in order to capture the full crush depth.

2.  Cases involving EDSMAC4 created on earlier (pre-Version 5)
    HVE versions did not properly assign inter-vehicle friction 
    coefficient. Instead of assigning the value from the new
    Set-up, Vehicle Mesh dialog, it was pulled from the original
    memory location in the Calculation Options dialog. This has 
    been corrected.

Section C: Other Changes
1.  The Get Surface Information option is no longer displayed 
    in the EDSMAC4 Calculation Options dialog. It has been moved
    to HVE's Options Menu.


===<Part 8: Changes to EDHIS Software>=======================

Section A: Enhancements
(none)

Section B: Bug Fixes
1.  HVE was not properly setting the selectability of Contact
    Surfaces in the Variable Selection dialog, meaning they could
    not be added to a Key Results Window or Variable Output
    Table. This has been corrected.

Section C: Other Changes
1.  EDHIS benefits from the redesigned Collision Pulse dialog
    (see Part 1: Changes to HVE Software, Other Changes).


===<Part 9: Changes to EDVSM Software>=======================

Section A: Enhancements
1.  Tire Radial Deflection has been added to the Variable Output, 
    Tire group.
2.  EDVSM now uses tessellated meshes (see Event Set-up, Vehicle 
    Mesh dialog) in rollover simulations during which the
    vehicle body contacts the terrain.

Section B: Bug Fixes
1.  EDVSM now displays the dynamic wheel position in the Variable
    Output, Wheels group, showing small changes in the wheel 
    y-coordinate due to suspension effects.

	NOTE: This effect has always been calculated and used
	      by EDVSM; it simply was not previously displayed
	      in Variable Output.

2.  The sign of wheel camber angle was incorrect for the left
    rear wheel of a vehicle with an independent rear suspension for
    which the camber angle was not a mirror image during jounce 
    and rebound. This has been corrected.

	NOTE: This change may cause small differences
	      in results between this and previous versions
	      for simulations fitting the situation described 
	      above.

3.  EDVSM was using a stale value of the sign and cosine of the
    earth-fixed wheel camber angle relative to the terrain.
    This has been corrected.

	NOTE: This error (which exists in the original 1976
	      HVOSM code) may cause small differences
	      in results between this and previous versions.

Section C: Other Changes
1.  The Get Surface Information option is no longer displayed 
    in the EDVSM Calculation Options dialog. It has been moved
    to HVE's Options Menu.


===<Part 10: Changes to EDGEN Software>=======================

Section A: Enhancements
(none)

Section B: Bug Fixes
(none)

Section C: Other Changes
(none)


===<Part 11: Changes to EDVDS Software>======================

Section A: Enhancements
(none)

Section B: Bug Fixes
(none)  

Section C: Other Changes
1.  The Get Surface Information option is no longer displayed 
    in the EDVDS Calculation Options dialog. It has been moved
    to HVE's Options Menu.

	Toyota Corolla LE				2003 - 2005

2.  The 175/70R13 and 185/70R13 tires had the slide friction value 
    set to 0.564 for all loads. The slide friction values should
    be 0.732, 0.642 and 0.564 for the 3 loads (in increasing order).
    This has been corrected.

3.  The Generic Class 3 Truck had all Suspension Null Band values 
    set to 0.0 in/sec. This caused unpredictable results in SIMON
    and EDVDS simulations. This has been corrected. The Null Band
    is now set to 5.0 in/sec.
4.  The 2000-2003 Acura TL engine was listed as a 4-cylinder; it 
    should have been 6-cylinder (same data, just misnamed).
