Mercedes-Benz SLS AMG "Gullwing"
The SLS AMG is powered by a 6208cc V8 engine, called the M159, which is based on the M156 as used in the E 63 AMG and certain other AMG models in the Mercedes-Benz lineup.
The bore and stroke remains at 102.2 mm and 94.6 mm, but high-strength components, forged pistons, improved dry sump lubrication, an optmised crankcase structure and reduced overall weight make this engine an even better performer than the M156.
In this application it boasts some 571 PS (420 kW) at 6800 rpm and 650 Nm of torque at 4750 rpm. This is enough to propel the 1620 kg coupé to 100 km/h from rest in a claimed 3.8 seconds, and on to an electronically-limited top speed of 317 km/h.
Aston Martin V12 Vantage.
The engine features a number of enhancements over the standard 6.0-litre V12 found in the DB9. These include a ‘by-pass’ engine air intake port that opens up at 5500 rpm, a revised induction system and re-profiled air inlet ports that further improve airflow into the combustion chamber to improve performance.
The naturally aspirated 6.0-litre V12 hand-built engine produces 510 bhp (380 kW / 517 PS) at 6500 rpm and 570 Nm (420 lb ft) of torque giving the driver access to high levels of power and torque at all engine speeds. Unique to the V12 Vantage is a ‘Sport’ button which allows the driver to choose between two powertrain modes.
The default ‘normal’ provides a more progressive, throttle response, suited to more everyday situations, such as driving in urban areas, heavy traffic, or in challenging weather conditions. Selecting ‘Sport’ mode delivers a sharper throttle response together with a sportier exhaust note. This mode is designed for use in more dynamic driving situations where sharper responses are required.
