| Test Driver Ratings & Comments |
|---|
| Acceleration comments | Tried default Drive, Sport and Launch transmission modes. I don't believe it's possible to completely defeat traction control, or maybe the P Zeros are so sticky that they prevent wheelspin(?). At any rate, the quickest run was with Launch Control and traction control in Track mode. There's a fairly cryptic engagement procedure ensuring you know what you're doing, but it works very well: It briefly hangs the revs then drops the hammer and the rears struggle for traction. In this mode, it auto-upshifts 1-2, but requires the driver to manually upshift thereafter (without an indicated redline, but a shift light). Shifts are nearly seamless, but slightly longer than we've witnessed with automated manual transmission cars. Sounds and feels faster than the clock reports. |
| Braking comments | Soft pedal, and the brakes like some heat for maximum effectiveness, but the results are indisputable and seemingly unrelenting. First stop was "longest" at 114.6 feet, and the last two stops of seven were the shortest at 105 feet. Little dive in Normal suspension damping mode; zero in Track damping mode. Some expected/typical scuffing noise from the front brakes (carbon-composite at all corners). |
| Handling comments | Slalom: Track mode ESC is "off" enough to be considered off, but technically it's still lurking waaay back there. Essentially, as long as the driver is in control (using effective throttle/steering input) and staying ahead, it'll allow the proper amount of slide to be useful. That said, what a wonderful car: What feels a little ponderous at low speeds shrink-wraps and becomes a precise and predictable sports car with added speed. What's more, it has an effortless competence and a gracefully predictable manner at the limit. The only other car that comes to mind with similar attributes is the McLaren MP4-12C. Front end is obedient and tactile until super-mild understeer creeps in, then throttle manipulation produces the kind of understeer/oversteer trade-off one hopes to receive. There's a slight throttle closure at exit, but there's also some sort of limited-slip differential at work that helps straighten the car out. Magic and rewarding and confidence-inspiring. Skid pad: Again, with the ESC Track mode, there's mild understeer on the limit and the threshold for intervention is just outside an ideal amount of slip, so it's essentially off. Steering is very informative. With ESC on, it takes throttle away slightly below the limit. |
