| Acceleration comments | G's honking 7,600-rpm redline defines it as a true sport coupe. It might not be silky smooth up there, but it is effective. Drive it hard and it pays off with ample speed. |
| Braking rating | Excellent |
| Braking comments | Solid, consistent pedal every stop. Effectiveness comes early in travel. Overall, this brake pedal inspires confidence. |
| Handling rating | Very Good |
| Handling comments | Good at-limit chassis balance is somewhat hampered by slow-reacting LSD on skid pad. Heavy steering, which is burdensome in normal driving, offers good at-the-limit feel and feedback. |
