Visually it starts with a chopped front windshield and side glass, creating a lower stance that's picked up by the hulking new rear decklid. A pair of throwback aerodynamic humps stand proud but, in breaking the retro theme, that surface is made of carbon fiber. The front hood and fenders are also made of the stuff, while the front and rear fascias are cast of lightweight polyurethane.
Brakes are lightweight, carbon-ceramic and the only transmission on offer is a six-speed manual, 9 pounds lighter than Porsche's seven-speed box, 40 pounds lighter than the PDK and, in my experience, far more rewarding than either of those two.
The light-weighting continues on the inside, deleting the car's air-conditioning system -- though buyers who prefer comfort to purity can have it added back as a no-cost option. There may not be a need, however, as the car doesn't really have a roof. There is a manual, fabric top, but that's likely not the kind of thing you'll want to fiddle with every day.
