The 201-hp 1.8-liter four in the C250 Coupe combines numerous advances and an intercooled turbo to deliver 229 lb-ft of peak torque, more than the previous V-6. Its rapid-multispark ignition can fire up to four times per millisecond. New high-pressure Direct Injection can microscopically fine-tune the fuel spray in 0.1 milliseconds, reducing emissions, fuel consumption and noise. A lightweight diecast-alloy block, quicker and more widely variable valve timing, reduced friction, and clever "on-demand" ancillary components like the alternator further boost efficiency.
The industry's first 7-speed automatic transmission remains one of the most versatile automatics on the market. A wide range of closely spaced gear ratios delivers the ideal response for virtually every driving situation, for smooth cruising, quick acceleration, and thanks to two overdrive ratios, better highway fuel efficiency. Adaptive logic monitors your driving style and adjusts its shift points to match, while Touch Shift control and standard paddle shifters offer manual-style shifting enjoyment anytime you want it.
