Background
The E46 was the fourth generation of BMW’s 3 Series compact executive line and it covers models produced in the Chris Bangle design era from 1997 to 2006 - by which time it was being phased out alongside the replacement E90 model.
Alpina have been developing limited-run, high-performance variants of BMWs since the mid-70s and, as their production has become so integrated with BMW’s own, they are now officially regarded as a manufacturer rather than an aftermarket tuning company. This means that their cars can be badged and registered as Alpina, but are fully covered by BMW servicing and warranty.
Once the Alpina-tuned engine and BMW body are united, production switches to Alpina’s plant for hand-applied interior upgrades and other unique performance and styling components, such as the 20-spoke alloy wheels.
Whilst the E46 B3 wasn’t one of Alpina’s better known models, they produced three variants of it between 1999 and 2006. The first was the B3, which was joined two years later by the all-wheel-drive B3 ALLRAD and then replaced in 2002 by the B3 S like you see for sale here.
The B3 S gave similar performance to BMW’s M3 but with more comfort and exclusivity and, unlike the M3 which was only available in coupé and cabriolet form, the Alpina also came as a saloon or estate.
The S had Alpina’s hand-built 3.4-litre (3346cc) straight-six engine which had a special cylinder head, crankshaft and high strength pistons, and delivered 305bhp with 267lb.ft of torque. Transmission options were either the 5-speed Switch-Tronic automatic or 6-speed Getrag manual.
