Today's car is the Alfa Romeo 164 Procar! (forum topic: http://forum.stunts.hu/index.php?topic=3728.0):
Nice pick!

Flat track top speed: (how to calculate it?)
It can be calculated from the car parameters by finding out when the aerodynamic drag equals the engine drive (see
the Wiki for the formulas). Alternatively, set up a large enough banked oval (I normally use my test track, attached below, though you might want to make it even larger), drive as fast as you can for two minutes or so, let go off the gas, crash and look at the reported top speed. By the way, now that I found a little more time I have replaced the 0-60 and flat track top speed values in my earlier reports, which I had quoted from Ryoma's fact sheets, with measured ones.
Today I'll report on the two Vectors! First, the
Vector WX3 (
forum thread):

- Gears: 3
- Powergear: No (bug-free)
- Flat track top speed: 245 mph
- Real top speed: 245 mph
- 0-60 mph: 3.4 s
- Time to hill at Default (auto gears): 9.60 s (References: Indy - 8.95 s; P962 - 10.00 s)
- Default test lap (NoRH, classic line): 1:19.95
- First impressions: Three gears, 245 mph, a lot of second-gear torque and not much grip to go with it. The WX3 can be thought of as an alternative to Zapper's KITT, the main difference being that it has conventional supercar performance instead of the pursuit mode. At any rate, it is a very challenging car.
Next, the
Vector W8 (
forum thread):

- Gears: 3
- Powergear: Rigid
- Flat track top speed: 229 mph
- Real top speed: 245 mph
- 0-60 mph: 3.95 s
- Time to hill at Default (auto gears): 10.65 s (References: Jaguar - 10.20 s; F40 - 10.75 s; GTO - 12.10 s)
- Default test lap (NoRH, classic line): 1:24.65
- First impressions: Slightly slower and easier to tame than the WX3. The main point to consider about the W8 is that it has powergear, and I'm not sure ZakStunts can afford a fifth PG car in its roster.
