Test Driver Ratings & Comments
Acceleration commentsWith traction control on and a quick clutch uptake, the car bogs heavily, so I had to feather the clutch on for a decent launch. With T/C off, the opposite is true: It'll boil the tires with ease. It's one of those cars that likes a little bit of initial wheelspin, but going to WOT too soon ends up blowing the run. So, a 2,750-rpm quick clutch, but then patience/prudence is required to maintain ideal traction all the way to the middle/top of 1st gear. Power seems to fade near redline, and short shifting seemed to help rather than hurt quarter-mile time and trap.
Braking commentsBrakes are nearly fade-free, only varying 2 feet over six stops from 60 mph. Pedal feel is solid and dead consistent; minimal dive and zero wiggle or wander. Noticed some steering wheel shake on the run up to 65 mph, but not under braking. Missing a wheel weight, perhaps?
Handling comments"Skid pad: (DSC Off) If I only had feel to go by instead of the electronic timer, I would've guessed about 0.85-0.90g, so imagine my surprise when it posted a 0.96. At this speed, the 1M gently understeers, and trying to kick the tail out with a couple throttle jabs only makes it go wide. While there's no question that the steering precision is there and the weight is appropriate, "feel" is sadly lacking. I never quite know what the front tires are enduring down there and they don't make much noise either. With DSC on MDM, it was actually easier to keep the car nailed to the painted line all the way around.
