If you want to beat darius, the best and easiest car to use is a viper. sell the gallardo a try to raise money. the viper is the best way to win the canyon.
A2
: 
I disagree with that not that I dont like the viper and all but I sold all my cars and made enough cash to buy the Mercedes Mclaren if you get that car and modifie it I can garatee you will beat him it worked for me and it could work for you!.
A3
: 
Definitely the best car to beat Darius in the Canyon with is the Mitsubishi Lancer. I had a Viper, tried to beat him at least five times with it, and it just couldn't handle the corners well enough. You'll own him with the Lancer.
A4
: 
No One is Wrong: You can beat Darius with any Number of cars
such as:
Toyota Supra
Mercades SLR
Chevy Corvette
Dodge Viper
Ford GT
The Concept Challenger.
All you have to do is tweak it right, and then learn how to drive it. Your more capable of pushing your car to the limits, then the computer is willing too.
A5
: 
Right, I used a non-customized gallardo to beat him, just use the handbrake in the canyons
A6
: 
Ladies and gents I have found the official answer to beating darius what you need to do is at the start of the race in the canyon, the first corner you come across darius will slow down, come in on the left side near the edge and overtake him, might not work the first couple of tries. finish the race with over 120,000 points

: 
Sell the galardo and buy the carrera gt and sup it up I passed him goin 212

I agree with awser 3. the lancer is amazing it is fast and it has amazing handling.I think it is one of the best cars on the game.i got mine to go 243 on a strait just tune it right and get infinet nos and you r good to go.
A9
: 
I disagree with all of the answers, the gallardo should work fine. just put the engine all to top speed and handling all to oversteer, make sure you use custom wheels, don't make the rims to large though I have a gallardo to and I have heavily customized it, I can get it to go 280mph on a strait
