Petrol 6-cylinder in-line and V-shaped engines E240, E280, E320 (Mercedes-Benz E-Class W210)

The E 240 model is equipped with a 6-cylinder V-shaped engine with a displacement of 2.4 liters and a power of 170 hp. The engine is the successor of the 4-cylinder version of the E 230.

During 1997, the E-Class engine range was thoroughly revised. As a result, the E 280 and E 320 models were introduced, equipped with 6-cylinder V-engines – the first examples of the new M 112 engine series. These engines replaced the old 6-cylinder in-line units of the same displacement. The power of the V6 engines is 204 and 224 hp, respectively. For comparison: the in-line engines of the same displacement in the E-Class of the 1996 model year had 193 and 220 hp. The torque characteristic of both V-engines is flat in the range of 3000–5000 min⁻¹, which allows more frequent use of higher gears, reducing engine speed and, accordingly, fuel consumption. To reduce the vibration load of the V-engine, an additional balancing shaft was used. The use of lightweight materials made the V-engines 25% lighter than the in-line engines. These engines were the first to feature cylinder liners made from light alloys, which saved fuel thanks to a low-friction coating. Emissions were significantly reduced thanks to the use of a three-valve cylinder head and two spark plugs per cylinder. These measures also contributed to a reduction in fuel consumption of 9–13% for the E 280 compared to its predecessor.
