THE C4S 911's styling was inspired by the 911 Turbo, with which it shares its wider bodyshell and more aggressive plastics. Like the Turbo, the C4S has 60mm wider rear wheel arches to accommodate wider wheel tracks and the massive 295/30-section rear tyres on Turbo-look 18-inch alloy wheels. Where C4S departs, however, is in its use of the standard 911's extendable rear spoiler (which extends at 120km/h and retracts when speed falls below 80km/h), rather than the Turbo's fixed rear wing. Also, given it misses out on the flagship's turbocharged engine (and therefore intercoolers), the C4S goes without the Turbo's prominent side air scoops, which is said to reduce its aerodynamic drag figure to a 911-like 0.30Cd instead of the Turbo's less slippery 0.31. Apart from its prominent rear, titanium coloured "Carrera 4S" bootlid badging - plus discreet "4S" badges on all four wheel centres - C4S is differentiated from other 911s by its use of a red light strip at the lower edge of the engine compartment lid, which visually links the two rear lights. C4S also gets metallic paint and an electric glass sunroof as standard.
