BMW M3 E46
The BMW M3 is a high performance BMW version of the popular BMW 3-Series compact automobile. M3 models have been derived from the E30, E36, E46 and E90/E92/E93 3-series. Common upgrades over the "standard" 3-Series automobiles include: more powerful and responsive engines, improved handling/suspension, more aggressive aerodynamics/body, and multiple interior/exterior accents with the "M"/Motorsport nomenclature.
Mechanics:
The E46 M3 was first introduced in October of 2000 and appeared worldwide with the new 3.2-liter S54B32 engine. At the time of the car's introduction, this engine had the highest specific output naturally aspirated engine ever made by BMW, producing 338 horsepower and 273 lb.-ft. of torque.
The first batch of E46 M3s delivered were Laguna Seca Blue. The available SMG Drivelogic (also known as SMG II) transmission, a Formula 1-style electrohydraulic manual gearbox with no clutch pedal and steering wheel-mounted paddle shifters, is also a highlight. The model also came with a new 6-speed transmission and redline RPM of 8,000, a first for any BMW. The engine also consisted of six independent throttle bodies and electronically driven throttles (without a cable).
In the US, the E46 finally comes with virtually the same engine output as the European version, unlike in the E36 where it was heavily detuned. Power is now at 333 horsepower, five down on the German model due to an extra catalytic converter in the downpipe.
Styling:
The E46 M3 comes in two models: two-door coupe and a two-door convertible.
Hitting the Tarmac:
The E46 M3 goes from 0-60 mph in 4.5 seconds for manual and 4.7 seconds for SMG. The convertible goes from 0-60 in 5.1 seconds. It has a top speed of 185 mph (155 mph electronically limited) and can do ¼ mile in 13.3 seconds at 104 mph.
Special Models:
There are three different E46 M3s produced: The Model M3 (Sport, Winter, Competition), the M3 CSL and the M3 GTR V8 that had limited production.
The M3 GTR came to life in February 2001 and was powered by a 4000cc V8 that produced 444 horsepower. Unlike the straight-six powered M3 versions, which were outpaced by the Porsche 996 GT3, the racing version of the E46 M3 GTR 16 was very successful in the American Le Mans Series (ALMS), entered by Schnitzer Motorsport.
The M3 CSL (E46) had a limited run of less than 1,400 units between June and December of 2003. The CSL (Coupe Sport Lightweight) received an aggressive weight reduction campaign, more power (up to 380 hp), and sharper handling characteristics than the standard M3, courtesy of larger anti-roll bars, stiffer spring rates, and semi-slick racing compound tires (Michelin Pilot Sport Cups). BMW never exported the CSL to the United States, although some parts from it were later made available on the regular M3 as part of an optional Competition Package.
While it is known as the M3 Competition Package in the US and mainland Europe, it is also known as the M3 CS Club Sport in the UK. The $4,000 option, which offered a number of upgrades taken from M3 CSL. The package includes: 19-inch BBS spin-cast (flow formed) alloy wheels (marketed as "forged"); specially tuned spring rates for the Competition Package; this was carried over to all M3 production from 12/04 on; CSL steering rack: More direct steering ratio of 14.5:1 (vs. standard M3's 15.4:1; CSL's M-Track Mode DSC with a button mounted on the steering wheel (deletion of cruise control and steering wheel mounted radio/phone controls); CSL's Compound cross-drilled rotors; larger front rotor of 13.6 inches (from 12.6 inches) with black painted calipers; Alcantara steering wheel, gear lever and hand brake; and a unique cube aluminum interior trim.
