Holy Grail Alpina B6 3.5 S for sale
The BMW tuner doesn't tend to go near M cars, but when it does...
Alpina doesn’t usually mess with BMW M cars. The tuning arm would rather take, say, a regular 3 Series, give it a bit more power, expertly revise the chassis and slap on some pinstripes than take the already blisteringly quick M3 and make it even faster. Granted, it’s dabbled in the track stuff before (think B3 GT3) but for most of its history, it’s been happy to leave that sort of thing to the M squad.
It has, however, given the Alpina treatment to at least one M car before. A few years into the E30 M3’s lifespan, the tuner elected to give the car a once-over to see what’s what. Immediately, its attention was drawn to the 2.3-litre four-pot. This was originally chosen because it proved to be lighter than the six-cylinder M88 engine that powered the M1 - and that would prove critical to the M3’s success in touring car championships across the globe. But Alpina didn’t have to worry about homologation rules (for motorsport, at least), nor did it have to consider whether the changes it made would impact the car’s performance on the racing scene, so it set out to find a suitable replacement for the purposeful – if not quite as characterful – S14 engine.
BMW’s 3.5-litre M30 straight-six was chosen, before being Alpina-fied with a comprehensive list of upgrades. Shorter Mahle pistons were fitted, along with longer con rods, revised cylinder head, an uprated cooling system and a remap to the Bosch ECU to tie it all together. This saw power leap from 218hp in the stock M3 to 260hp, which was pretty punchy by 1990 standards, making the B6 3.5 S comfortably the most powerful road-going version of the E30 at the time – and it remains the only official(ish) installation of a straight-six in the M3’s first iteration.
Naturally, that came with a hefty weight penalty and mucked about with the balance and suspension setup somewhat. Thankfully, there was an easy fix. BMW had already developed stiffer springs for M3s fitted with air conditioning to handle the extra weight at the front of the car, giving Alpina a plug-and-play solution for its six-cylinder rework. The rear was left unchanged, as was the E30’s brilliantly boxy aero kit. What helps this particular car stand out from regular M3s, given it doesn’t come with the tuning firm’s deco pack, is its Alpina Blue finish, a new steering wheel and gear lever, as well as the company’s signature blue and green stripes down the centre of the seats. And, of course, a set of 16-inch multi-spoke Alpina wheels to top it all off.
That paints a picture of something rather special. Not only is the B6 3.5 S among the finest of all E30 variants, it’s also widely considered to be one of the greatest Alpinas ever made – a tad ironic given that the company hasn’t touched a fully-fledged M car since. It’s mighty rare, too, with only 62 examples making it out of Buchloe versus the near-18,000-strong production run of the E30 M3.
Which inevitably means you’ll need to pay top dollar to get your hands on one. This example is listed at £189,000 at Munich Legends, but you do get a chunky history file documenting the car’s life from its original sale in France in 1990 before arriving in the UK a year later. The last owner purchased it in 1992, and is presumably responsible for clocking up the vast majority of the 84,000 miles the car has under its belt. Don’t let that put you off though; Alpinas eat miles (although they prefer kilometres) for breakfast, and all the images in the ad suggest it’s been well looked after. It’s not often you come across hidden gems like these, so you’d better jump in before word gets out.
Love Alpina engines/tuning packages and their suspension kits, but given £190k for an E30 M3 i'd be seeking out a Hartge H35 for a proper ///M engine.
But not this.
I should probably get my coat but I never thought the add ons did the car any favors and I lived in Germany when the 3 was box fresh, while a late 325i can look amazing in a dark metallic tis to me looks a little blingy.
Price is certainly punchy. I doubt it’ll actually see much use by the next owner because of said price which is a shame.
Owned 4 times a e30 M3 all 4 different, from a Evo 1 to a katted special exclusive but just 195hp one, to a Alpina B6 3.5S to a M3 e30 with tuned e36 S50B30 engine (and some other parts) and that last one was the best! it had the power and the handling, which the Alpina B6 S did not have, that one felt nose heavy compared to all 3 others.
So yes, I also think that the Hartge H35-24 e30 M3 was a better drivers car then the Alpina B6s
this was my best e30 M3 with the S50B30 tuned to 310hp long time ago (in the nineties) see old scanned in pictures.
and this that Alpina B6s after factory build with fender lips, vey nicely Germanly done :-)
old scanned in pictures from long long time ago (in the nineties)... color also purple-ish Macao Blue seem to be the name, looks almost black in those old scanned in pictures, but was purple metallic lighter then in those pictures.
as you can spot also a Gutmann Dimma purple 205 gTi by my other e30 M3 the exclusive one with leather as much as you could have strange one.
(I would be happy with just a sorted 325i sport!)
Alpina also had their normal-ish e30 B6 with such 3.5 engine, just like Hartge had with their H35-24 and AC Schnitzer and sorts.
