| Test Driver Ratings & Comments |
|---|
| Acceleration comments | Fairly dead below 3,500 rpm, then things heat up. Sounds mean up high without ever being over the top. Power braking to 2,100 rpm helped times, but with AWD there was never even a chirp from the tires. Shifts came at 6,700 rpm in Drive. Manual shifting is via steering wheel paddles, and these shifts were exceptionally fast, but times proved no quicker. Will hold gears to 7,000-rpm limiter. Blips throttle on downshifts. |
| Braking comments | Spongy, long-travel pedal. Not confidence-inspiring. Would pull hard enough to the right at the end of each stop that countersteering was needed. First stop was 129 feet. Second stop was shortest at 123 feet. Sixth and final stop was longest at 132 feet. |
| Handling comments | Skid pad: Front end plows like crazy and there's almost nothing to be done about it. Drop-throttle has almost zero effect. Overly light steering offers little to no feel. Slalom: Odd handling mix. Steering/turn-in is quick for such a big and heavy luxury car. Matters little, though, because the steering has so little actual feel. And the suspension and tires can't cash the checks the steering is trying to write. Tires have little grip and the suspension allows lots of body roll, even in Sport mode. What's more, the rear will start to come around (with ESC off) if you get too aggressive with steering inputs. Easy to fall behind with this car, and that's when the rear starts to step out. Slow-in/fast-out definitely works best. |
