I started using the tesla a couple weeks ago because I wanted to see how good it really was now that I have gotten better at driving.. and I noticed that on a one-make race with a stock tesla roadster there was no way to launch like the AI do.. The AI seem to charge up their wheels without moving and there's no way for users to do it. This is only for races that don't start as rolling start (i.e. one make race, not sure of other races that start as a grid).

It seems that our wheels are locked from turning, where the AI are just prevented from moving in the forward direction. Basically, during the starting grid, their tires are turning with tire smoke.

Edit: The strange AI tire spin only seems to happen with the Tesla Roadster. The Citroen GT Concept works fine, and the Honda Dualnote used by the AI seems to work fine (if anything, with the Dualnote they're actually conservative on their launch). So yeah this only affects the Tesla it would seem.


(Image is 783kb) You can make out which car is mine from the thumbnail, it's the yellow one without a giant smoke trail behind it >.>

Yeah that is pretty crazy. Turned on my game to see it. I don't even think the AI tires are moving, they just start smoking before the race starts.
 
Perhaps the AI cars run on a different driving physics engine that allows them to more easily spin the tires of electrically-powered cars?

Its not that ... It's that they are smoking the tires before the race starts even. On my screen it appeared that the tires weren't even spinning while they started smoking.

When I asked this I tested it a few times and they start to smoke their tires just as the race starts.

That is very odd, i have also noticed that the Tesla Roadster is slower in the game than it is in real life.

This is just because different versions were released.. I think the GT5 one is based off the original release, which was slightly slower.

@RocZX Sorry didn't know there was a thread already.. well I have posted the pic anyways :\ threads could potentially be merged.
 
No I don't believe it's just Daytona.. the AI seems to do this on every track that starts as a grid. I thought so too, but I went back and tried a number of different things to even get the tires to spin at all off a launch and you can't even do it well with comfort hards AND full weight reduction. Not nearly as much as the AI do.. the AI's tires are smoking before the race even starts. :P
 
There is another thing with this car that seems strange. put it in reverse and she will wheel spin, then hold on the power and see how fast she goes backwards!!!!!!! :o

Thats because there is only two gears forward and reverse. The car should go as fast in reverse as it does in the forward gear.

It's still too slow, and I don't think subsequent versions of the Roadster were *much* faster. Time it in GT5 and you're looking at 0-60mph in about 5-6 seconds, pretty sure even the first roadster was sub-4 seconds. It should be in Ferrari territory on tracks where its max speed is enough.

Making it lighter helps a little, but is unrealistic too 👎

Call me crazy but surley in real life the gearing for reverse would be lower? or at least they would limit the rmp in reverse.

The Tesla has a fixed single speed gearbox. So reverse would be the same as forward, minus the aerodynamic difference of the front and rear.

Transmission

Starting in September 2008 Tesla Motors selected BorgWarner to manufacture gearboxes and began equipping all Roadsters with a single speed, fixed gear gearbox (8.2752:1) with an electrically actuated parking pawl mechanism and a mechanical lubrication pump.[12]
The company previously worked with several companies, including XTrac and Magna International, to find the right automatic transmission, but a two-gear solution proved to be too challenging. This led to substantial delays in production. At the "Town Hall Meeting" with owners in December 2007, Tesla announced plans to ship the initial 2008 Roadsters with their interim Magna two-speed direct shift manual transmissions locked into second gear, limiting the performance of the car to less than what was originally stated (0 to 60 mph (0 to 97 km/h) in 5.7 seconds instead of the announced 4.0 seconds). Tesla also announced it would upgrade those transmissions under warranty when the final transmission became available.[45][47][85] At the "Town Hall Meeting" with owners on January 30, 2008, Tesla Motors described the planned transmission upgrade as a single-speed gearbox with a drive ratio of 8.27:1 combined with improved electronics and motor cooling that retain the acceleration from 0 to 60 mph (0 to 97 km/h) in under 4 seconds and an improved motor limit of 14,000 rpm to retain the 125 mph (201 km/h) top speed.[86] The upgraded system also improved the maximum torque from 200 to 280 ft·lbf (270 to 380 N·m) and improves the Roadster's quarter mile times.

Gear selector
In the interior the gear selector is similar to a push-button automatic with buttons labeled P, R, N and D while some earlier models have a gear lever similar to that in cars with manual transmission.
