The pretty dual exhaust system was scrapped for this single-pipe setup, so it can get all of that massive air rushing out of the exhaust. With all of its 4-inches of glory, backpressure is reduced.
Upon first glance, we don’t see any major changes inside the cabin. The whole purpose of the Hyper1000 and Hyper1200 phases are to allow HyperCar customers to have over 1000 horsepower and have it be drivable everywhere they go–from the street to the track–without spending seven figures.
The McLaren MP4-12C has three modes to drive in, including normal, sport and track. When testing on a two-wheel dyno with the McLaren scan tool, you can only get the “normal” mode, which limits not only the RPM but also (and as a result) the power. This may be why you see some articles online that show reduced RPM, and a lower wheel-horsepower output than what HyperCar was able to get out of a stock 12C.
One of the things Hypercar was able to do is crack the ECU codes for full tuning and testing. So, not only can they tune the cars to get full power on the street, but they can also test this way on a two-wheel dyno. Without this capability, you’d need an all-wheel dyno with the front and rear rollers connected.
Save for a Sparco seat and rollbar, this interior wasn’t messed with too much in the Hyper1200. When it comes to the rollbar, HyperCar drills them into the one-piece carbon tub of the McLaren. This takes a tremendous amount of care, not just in the drilling but also in the amount of torque applied when mounting.
Well, this should make the car less intimidating to drive for millennials (no offense).
