The first M3 produced 192 hp from its 2.3-liter four-cylinder engine during its 1988-1991 model year run. A legend was born and Americans embraced the high-rpm, naturally-aspirated M concept. The next generation arrived in 1995 with a 3.0-liter (and later, 3.2-liter) 240-hp inline-six powerplant. In 1997 the first M3 Sedan joined the family and the first M3 Convertible followed shortly thereafter. The most-recent version, available as either a coupe or convertible from 2001-2006, again was offered with six-cylinder power, this time providing 333 hp from its 3.2 liters. This vehicle was BMW’s first use of SMG (Sequential Manual Gearbox) for the US market.

The move to eight cylinders in the fourth generation BMW M3 provides a powerplant offering the seemingly disparate characteristics of more power, increased efficiency and reduced weight when compared with the previous six-cylinder M3 engine. Displacing 3,999 cubic centimeters (4.0 liters), the new light-alloy engine produces 414 hp at 8,300 rpm and 295 pound-feet of torque at 3,900 rpm with 85 percent of the maximum torque available consistently through 6,500 rpm. This power output represents a 15-percent increase over the six-cylinder from the last generation M3 and it comes with an eight-percent fuel-economy improvement when compared to its predecessor. Compression ratio is dialed in to 12.0:1 and redline is set at 8,400 rpm.
One of the most waited cars this year, the new C63 AMG ensures exciting motor racing at the highest level. Powered by an AMG 6.3 liter V8 engine, the C63 AMG has a maximum power of 457 hp and a maximum peak torque 600 Nm and makes the 0 to 60 mph sprint in just 4.3 seconds and has a top speed electronically limited to 155 mph.
Merely the appearance of the C 63 AMG is impressive enough, with its wide, road-hugging stance. The new bonnet with its prominent power domes conceals the independently developed AMG 6.3-litre V8 engine, which develops a fulminating 336 kW/457 hp at 6800 rpm from a displacement of 6208 cubic centimetres. In this respect the C 63 AMG comes very close to the 470 or so horsepower delivered by the AMG C-Class racing touring car in the DTM series. This high output also benefits the power-to-weight ratio, which is a very favourable 3.6 kg/hp.

The torque developed by the AMG 6.3-litre V8 engine need fear no comparison either. The maximum of 600 newton metres at 5000 rpm is unrivalled in this class, and the torque curve is equally impressive: from 2000 to 6250 rpm the driver always has more than 500 newton metres on tap – ideal for powerful acceleration in any engine speed range.
Audi S4
The future Audi S4 will be unveiled next year, probably in the same time with the 159 GTA at the Geneva Motor Show. It will be powered by a 4.2-litre V8 engine that delivers 340 hp.
Audi A4
Compared to the standard A4 unveiled this year at the Frankfurt Motor Show it will feature S-style bumpers, a small bootlid spoiler as well as quad exhaust pipes.
