Background
The E46 might not be the best-looking BMW ever built but it might just be the best to own and drive, which makes the E46 M3 the very best-of-the-best.
But first, some background. The fourth generation 3-Series was launched in 1997 in a wide range of body styles: a four-door saloon; a two-door coupe; a two-door convertible; a five-door estate; and a three-door hatchback. Also available with both a rear-wheel-drive chassis and four-wheel-drive, the E46 driver could also choose between a wide variety of both petrol and diesel engines, manual and automatic transmissions.
Competent beyond fault, the range might have had breadth but, if we’re being honest, it didn’t have a lot of depth. Until, that is, the introduction of the high-performance M3.
Launched in 2000, the M3 featured a 3.2-litre, straight-six, normally aspirated engine under the bonnet; with a whopping 338bhp and 269lb/ft of torque, the M3 could streak to 62mph in 5.1 seconds – and could do so whether it was fitted with the six-speed manual gearbox, or the six-speed SMG-II sequential flappy paddle gearbox. The top speed is artificially limited to 155mph, but two-and-a-half miles per minute is probably quick enough, eh?.
And it was no straight-line dragster, either; Car and Driver magazine tested it in the ‘States and recorded 0.89g in cornering force for the coupe, and 0.81g for the convertible. A limited-slip differential helps, as do sticky tyres on fat 19-inch alloy rims.
Weighing just over 1,500kgs, the M3 benefits from widened wheel arches, unique side skirts, and a modified front spoiler. There’s a discreet Gurney flap at the rear - and any aero-aid named after a legendary American racing driver can only be a good thing, right?
The chrome-plated gills distinguish the M3 from its lesser brethren, and they serve a purpose in ducting hot air out and away from the engine bay. Well, that’s what BMW thought they’d do. The reality is that they’re completely unnecessary, but the German firm retained them for their aesthetic appeal, a cosmetic sleight-of-hand that is partially compensated for by the presence of the functional ‘powerdome’ bonnet (no, we aren’t making that up…) and aerodynamic door mirrors.
The E46 M3 CS, which we have here, benefits from CSL alloys, CSL brakes, CSL steering rack and CSL steering wheel, along with the M-Track mode button and sports seats.
The M3 E46 died in 2006 after more than 85,000 had been built, split 56,000 for the coupe and 30,000 for the convertible.
