I do believe it's based on the old E36 M3 lump but may be wrong. Subtle styling, usually high spec as already been stated and a pretty damn good car. I seem to remember them opening them out to 3.4 litres later on, but I might have just made that up.Its Alpina's 3.3litre engine based on the BMW 6 cyl. They are fitted with Different cams, mahle pistons bigger throttle body etc
They are about .5second to 60 mph slower than an E46 M3..
The B3 3.3 and B3S engine is based on the S52B32 engine from the US-spec E36 M3 3.2 with 240 hp which has a regular M50 intake and hydraulic valve lifters. The cylinder head and the single-VANOS system have more in common with the regular M50 engine than any M-engine. Alpina have increased the bore to 86.4mm as well as a longer stroke (94mm). The cylinderhead is tuned in traditional fashion as well a new exhaust manifold. Extremely light pistons as well as a newly developed crankshaft have been used in conjunction with a new torsional-vibration damper, sustaining permanent revs of up to 7200 rpm with ease. The engine produces 280 bhp at 6100 rpm and a torque of 335 Nm at 4300 rpm. The new B3 is also very frugal, only 9,9 litre/100 km in mixed driving conditions
The standard gearbox is a Getrag six-speed unit but the five-speed Switch-Tronic box is available as an option.
Switchtronic gives you the choice of leaving everything to the semi-automatic box itself, or selecting your own gear using either the regular lever or small buttons behind the steering wheel spokes - right for up-shifts, left to change down.Guys,
I notice on nearly every websites that are selling these B3 3.3, wether it's BMW, Autotrader or Ebay, they all state a 'switch-tronic' box. What is this? Is this flappy paddles or not?
Bare with me, I'm just starting to get into quick BMW's!
No, optional extra more likely or standard on their big boaty cars possiblydon't alpinas have double glazing too?
