The 2018 Mercedes-Benz C200 EQ Boost is a saloon featuring a 1.5L turbocharged petrol engine with a 48-volt mild-hybrid system called 'EQ Boost'. This system adds 14hp, enables the engine to shut down for fuel-saving coasting, and recovers energy under deceleration, while the 9-speed automatic gearbox provides smooth gear changes. The saloon offers modern features like a 10.25-inch infotainment screen, a 12.3-inch digital cockpit, and an optional 'Driving Assistance' package for semi-autonomous driving.
