Test Driver Ratings & Comments
Acceleration commentsEven in its "Normal" setting and without "Launch" mode, the McLaren runs to 60 in 3.7 seconds. The only car with a launch control as easy and effective as this one is the 911 Turbo (997). The MP4-12C's system is essentially foolproof and extremely consistent. The thrill of hearing that V8 scream behind and the zero-shock upshifts feels almost like an amusement park ride. All I had to do was keep my eyes pinned on the horizon and watch the scenery grow increasingly blurry before standing on the brakes at about 135 mph. Thrilling, yet unchallenging.
Braking commentsNo surprise, the McLaren dives very little and there's absolutely no ABS or tire noise. It just stops. There is, however, a slight wiggle as the car searches for and sorts out available grip -- just like proper non-ABS threshold braking.
Handling commentsSkid pad: Steering is unfettered, friction-free but communicative about the front tires' impending slip. Odd, intermittent porpoising nudges the car slightly wide. Extremely mild-yet-stubborn understeer on the limit. Frustratingly, I wasn't able to coax rotation unless I REALLY wanted it to drift (with ESC off). Slalom: In Track Mode with ESC on, the car sensed the understeer and gently bled throttle at each cone to tuck the nose in. With ESC off, I tried to drive around the understeer by "jumping" off the throttle, but rather than rotation, it drifts as a unit, causing me to slide past the next cone (late). Finally, I managed to "beat" the ESC by throwing it in too fast, letting it scrub down with the understeer, then rolling back on the throttle for power oversteer. Mind you, this all happens with a 75-mph entry speed and should be terrifying, yet it is not. The steering is so precise, car is so neutral, that I could place it inch-perfect each time.
