I wasn’t sure exactly where to put this, so I figured here was as good as any place, but for those who are thinking about purchasing or who have purchased the ‘Alpinestars car pack’, be warned about the Bugatti EB110 engine swap. I build my cars all for speed and power (I mainly only race long sprints), so I tested the stock engine w/ upgrades first: puts out around 769hp with a TS of 238mph. Then I figured I’d try the swap and became very disappointed, very fast. It ups the HP to well over 1,300, but on the speed test it lacks… greatly, cutting the speed at about 187mph. And to make matters worse, the swap… was about 468,000 credits just for the engine, no upgrades. So be warned, all those who build cars for speed and power, the engine swap in the EB110 is no good. I blew over 450,000 credits and really wish I hadn’t now.
Find a tune to download. I found one and it now goes 274 MPH.
Or you could just time the top speed, have a play around with it!
Adjusting the gearing will make it go faster.
This.
Stick a race trans on that badboy, and tune it for top speed.
I know for a fact this car can go over 187mph with that engine, you just gave up too soon.
My EB110 will do 280mph+ Just tune the gears and itll go faster.
I doubt it.
I’m pretty sure all cars are limited to 272/273mph.

Ok, I partially stand corrected.
You could see the car struggling to beat 274/275. It took a draft/slipstream slingshot to get him there 
Yep drafting runs don’t really count for top end speed.
Why would the speed queen from Horizon 1 and Horizon 2 on 360 would be one of the slowest cars on Xbox One? Just think about it…
Even me, a rubbish tunner, made it go 280 mp/h (with a bit of help by drafting, but still…).
