2015 Alfa Romeo 4C speed |
The Alfa 4C is glorious, why you should care about the brand's return to the U.S.
It’s only once every other Halley’s Comet that an elemental sports car such as the 4C survives the gauntlet of federal regs walling off America from foreign death machines. The no-longer-imported Lotus Elise is the template; the Porsche Boxster/Cayman sits at the posh end of this narrow spectrum. Alfa 4C will land somewhere in between, improving on the Lotus’s few vague gestures toward occupant comfort while, compared with a highly burnished Porsche, exuding a certain improvisational kit-car feel, with its spyder headlights, some haphazardly routed cables, and a few wads of black tape.
Alfa, which started the project in 2010 but didn't approve production until after the 2011 Geneva auto show, sandwiches the world’s cheapest production carbon-fiber tub, hand-made and autoclave-baked at a supplier in central Italy, between two aluminum subframes. To the rear, a turbocharged and direct-injected 1742-cc four-cylinder with 237 badly misbehaving horses is located transversely. It sits between a pair of struts and the straw-thin tubes of the triangulated lower control arms. In front of the driver, an unassisted rack-and-pinion steering gear reaches toward knuckles supported by twin pairs of cast-aluminum A-shaped control arms.
The twin-cam engine is basically an alloy version of the base Giulietta’s cast-iron 1.7, but with improved air and fuel delivery and 21.8 psi of boost. To reduce lag, the engine uses “scavenging,” or excess valve overlap in low-rpm, open-throttle situations, keeping air flowing into the turbo. The peak torque of 258 lb-ft arrives at a diesel-like 2200 revs. Everything is overbuilt for the 4C’s 6500-rpm redline, meaning more power is likely slated for future editions.
