Description
The Mercedes-Benz M273 engine is a V8 automobile piston engine family used in the 2000s (decade). It was based on the similar M272 V6 introduced in 2004.
An evolution of the M113 V8,[1] all M273s have aluminium engine blocks, sequential fuel injection, forged steel connecting rods, a one-piece cast camshaft, and a magnesium intake manifold. The cylinders are lined with silicon/aluminium, and a dual-length variable-length intake manifold is fitted.
The E25 is a 2.5 L (2,496 cc) version. Bore and stroke dimension is 88 mm × 68.4 mm (3.46 in × 2.69 in). Output is 204 PS (150 kW; 201 bhp) at 6100 rpm with 245 N⋅m (181 lb⋅ft) of torque at 2900-5500 rpm.

E35[edit]
The E35 is a 3.5 L (3,498 cc) version. Bore and stroke dimension is 92.9 mm × 86 mm (3.66 in × 3.39 in). Output is 272 PS (200 kW; 268 bhp) at 6000 rpm with 350 N⋅m (258 lb⋅ft) of torque at 3500 rpm. A direct injected variant debuted in 2006 under the name Stratified-Charged Gasoline Injection (CGI). First fitted to the CLS350 CGI, it produces 292 PS (215 kW; 288 bhp) and 365 N⋅m (269 lb⋅ft) of torque while lowering fuel consumption. In 2008, the non-CGI engine was uprated to 316 PS (232 kW; 312 bhp) at 6500 rpm and 360 N⋅m (266 lb⋅ft) of torque at 4900 rpm with 350Nm being delivered at 2000rpm. This was achieved by raising the rev-limit to 7200 rpm, increasing the compression ratio using enhanced, weight-optimized pistons with a curved surface, reinforcements in the area of the piston pins, deeper pockets for the valve seats, single-stage intake manifold, lightweight valves with sodium cooling, conica
