what's the best speed car

If you have the money and have very good reactions and also don't mind crashing occasionaly/regularly, I would say a ford GT. But be warned that they are hard to control, especially when drafting. It takes me at least a couple of tries almost every race unless I get a very comfortable lead. If you beat the speed king, make a new blueprint for the 65' GTO, I love it. It takes way long than the GT to get up to speed, but believe it or not handles great at high speed. It'll have level 4 parts, and you can get the aero to level 4 easily, power about 1/2 up level 3 (the car will still e able to hit 250 if you know how to tune), and control about 1/2 way up level 3

The Lambourghini isn't even close to being the best speed car in the game anyways and the Nissan GT-R (R35) is designed more for grip anyways due to the bodywork, etc.
Go for either the Mitsubishi Evo X or Porsche 911 Turbo.

I used a Dodge Viper to own the speed competition, but it can somewhat be hard to handle in some tracks. I've tried both the GTO and GT and they've both screwed me over.

The pagani zonda is a great car for capturing high speeds...

personally the lambourghini is one of the best speed cars because its easy to handle and if you know how to control it you can easily stay at it's max speed or close to it. With it i barely total because when i slide a bit i can regain control within seconds unlike a lot of other cars like the evo IX.

how bout the mustang gt

Pagoni zonda is beast I completed a 2 minute race in 1 15 in that thing

I have a lambo that is free but doesn't have the power of the 640. Think it would work to defeat the speed king and Ryo Watanabi.

Oddly enough, I have a BMW M3 that's fairly good on the speed tracks. It's not the fastest out there, but it maintains it's speed and is nigh impossible to crash. I take a Lambo on the interstate and I'm flying around like crazy, but the Beamer is like glue on the road. Maybe it's only good for hilly tracks? Still, I like it.

Im playing with mustang GT and it's great! Only 640 hp with best parts and still goes 402kmh. Pretty good handling but my mustang doesnt accerlate so fast in start but it takes few seconds and your speed is about 370kmh. Should try! (remember.. I have my own tunes in my car so your car isnt that good for sure)

Honestly the pagoni is the best cause it has level three at the start when you buy it and plus if you get it's aero dynamics up it wont have any wind pressure against it so id choose the pagoni

I love the audi S3 it is not fast but so easy to control, and stays at it's top speed in most turns good for beating the speed king in.

Bugatti veyron or corvette z06. Bugatti goes the fastest of any car and the corvette with good parts can go fast

I'd chouse the nissan gt-r proto.i'ts it can beat the speed king with no tunning.

I used the evo and had no troubles so fast just leave it maxed out

Ive used many cars and the best I've found is the skyline it has great power and handeling and anough accel to get you going quick

The viper is a good car on cheats enter worldslongestlasting

Honestly I would use a lamborghini or a zonda I've tried the skyline it's good but it's not for me the 911 gt2 may be REALLY FAST but the stability sucks I hear the evo 9 is good or the viper the ford gt is ok but I really happens to skrew me over a lot so I typically use my lambo but it really depends on whats good for you
