Autotest BMW M550d xdrive
Bisher stand das Kürzel „M" bei BMW immer für die Muskelversionen von
benzingetriebenen Serienfahrzeugen. Beim neuen M550d xdrive packen die
Münchener Autobauer erstmals einen leistungsgesteigerten Diesel mit 381 PS

1988 BMW M5 The Ultimate Driving Machine
M5 is a performance version of BMW's 5-Series and created by BMW
Motorsports. First introduced at the Amsterdam Motor Show in 1984, the M5
has been made from various 5-Series versions throughout the years,
including the E28, E34, E39 and E60. Originally, the M5 was hand-built
utilizing the 535i chassis and a modified BMW M1 engine. When introduced,
it was the fastest production saloon car in the world.
In 1984 BMW offered multiple versions of the M5 to accommodate the
different markets and the rules that governed the production of vehicles in
each of those areas. There were Left Hand Drives, Right Hand Drives, Euro
Specs, North American Spec (NA), and South African (ZA) Spec M5. The North
American M5 versions were equipped with a catalytic converter which
degraded the horsepower from 286 to 256.
With the 286 horsepower engine, the Euro
spec M5's could race from zero to sixty in just 6.2 seconds. The North
American specs accomplished the sixty-mile-an-hour run in 6.5 seconds.
The production of the M5 on the E28 series platform lasted from 1984
through 1986. From 1989 through 1995 the M5 was produced on the E34
platform. For the North American market, production of the E34 M5 was from
1991 through 1993 and continued the tradition of being hand built usually
in teams and transpiring over a two week time period.
Under the hood was a modified inline-six cylinder engine from the E28 M5
and the E24 M635CSi. The bore and stroke were enlarged to a total capacity
of 3535 cc and a compression of 10:1. Unique to the M5 engine were a new
forged steel crankshaft, camshafts, and electronically controlled butterfly
valve. The result was 3.6 liters and 315 horsepower. The US and
Switzerland versions received catalytic converters and a lower horsepower rating, 310.
Power was dispersed to the rear wheels with the help of a Getrag 280/5
five-speed manual transmission. Standard was a limited slip differential
with a maximum locking of twenty-five percent.
