2011 BMW B3 S Biturbo Alpina


Alpina creates exclusive automobiles for a small circle of connoisseurs who appreciate the finest things in life – cars for gourmets, perhaps.

For over 50 years, the small autonomous family business has developed and produced cars, using BMWs as the starting point. Today, company founder Burkard Bovensiepen heads the company with his two sons Andreas and Florian.

The close cooperation with BMW is undoubtedly the basis for Alpina’s continued success. The cars produced are highly individual, but at the same time meet the stringent quality and safety standards that apply to large-scale car production.

From their back catalogue is the B3 S Biturbo, the marque’s take on the 335i. The renowned fettlers tuned the B3 S’s 3.0-litre, twin-turbocharged six-cylinder engine to produce 395bhp, a staggering 90bhp more than the 335i. Torque was up too by more than 100lb ft to a heady 398lb ft.

Figures taken by Autocar for the convertible gave a 0-62mph sprint time of just 4.9 seconds. And should you be Nürburgring bound, the possibility exists to test out the unrestricted 185mph top speed on the autobahn. Only the brave or perhaps foolhardy should apply!

Comparisons were of course made with the M3, which at the time had V8 power. Was it any quicker? In the real world, probably not.

However, chassis-wise the B3 S was way softer than the M3’s and that was entirely deliberate on Alpina’s behalf. The company’s bespoke wheels were lighter and losing the runflat tyres gave the Alpina’s ride a suppleness and civility that was unmatched by any 3-Series. All this without any major sacrifice in body control too.

Autocar found the B3 S to be monumentally quick on the road, demolishing even the shortest of straights in double quick time.

The automatic gearbox worked smoothly with that powerhouse of an engine, even blipping on downshifts when you chose to shift manually.

So, fast, refined and distinctive, that was the Alpina B3 S Biturbo, and we are delighted to be able to offer a prime example for sale, in convertible form.

The Vehicle

June 2011, the Alpina’s original owner took delivery just in time for a full summer’s top-down motoring. What a lucky individual. With the gleaming white paintwork, suddenly so very on trend, they must have cut quite a dash.

Now ten years old, and with four former registered keepers before our seller, the B3 S has covered less than 40,000 miles. Doubtless it has been a car for high days and holidays.

Watching the folding hardtop go through its cycle is quite mesmerising, though once folded it does eat into boot space a tad. However, leave the roof up and you have a civilised coupe with none of the downsides of a vulnerable soft-top.

Our seller has owned the car since 2018 and has kept up with the servicing and maintenance regime, easily done through any authorised BMW dealership or specialist.

It is now time for a change, so his loss is potentially your gain.

On the Outside

White paintwork is now so very popular, and we think it rather suits the B3 S, accentuating those lovely BMW lines. The Alpina body kit is subtle but does help the car to stand out from the masses and it shows how modifying should be done.

Alpina’s trademark multispoke wheels are the finishing touch and are quite distinctive.

The convertible roof functions as it should, its operation can be seen in our accompanying film clip.

There is a 5p size dent towards the front of the roof and a mark on the left-hand side C-pillar. We also note two small dings on the back bumper together with a scratch on the nearside corner.

The front bumper has a few small battle scars too and we have also spotted some minor scratches on the sills.

The offside back wheel shows some signs of kerbing, whilst that to the nearside front it is more severe. The tyre is damaged too and, in our opinion, should be replaced. There are many wheel repair specialists who can remedy the situation.

We would mention that the Michelin Pilot Sport tyres (an excellent premium brand) boast plenty of tread.

On the Inside

BMW is renowned for making lovely interiors. Comfortable seating that supports in all the right places is just the start. Controls that are logically laid out, an excellent driving position and you have all the right ingredients for a scintillating drive.

Alpina add a few subtle touches here and there, such as discreet badging on the seats, just to remind you that you are in something so very special. Oh, and the BMW badge is replaced on the steering wheel with one of Alpina’s finest.

The seats are covered in black leather and apart from a little wear to the driver’s seat bolster, no doubt from the seat belt rubbing, all is well. There is space for four adults to travel in reasonable comfort, though a little juggling of legroom may be required if rear seat passengers are on the tall side.

As one would expect, the equipment count is extensive. Electric heated seats up front, climate-controlled air conditioning, a quality music system and of course satellite navigation.

Carpets and overmats appear to be in good order, but we have spotted some marks to the interior headlining.

The boot area is in decent order, save for a patch of light staining on the right hand sized. Time to get the steam cleaner out…


We always include pictures of our car’s undersides, so pause a while and examine our photos. We think you will be impressed. Other than the usual road dirt, we cannot spot anything untoward, and all would appear to be commensurate with the car’s low mileage. We suspect the car may well have been spared much action during the worst winter weather.

Lifting the bonnet reveals a rather full engine bay. Alpina badging to confirm that the motor has been breathed upon by company’s finest engineers.

Clean, tidy and with no obvious signs of anything out of place, it is what we would expect with a pedigree car such as this that has been properly maintained.

History Highlights

We always like to find cars with the original book pack and service record. It is surprising how often they go astray. No such worries here.

The service book contains a raft of stamps from main dealers – Sytners, Vines, Listers… all familiar names.

The last service was carried out at BMW/MINI main dealers Berrys in Chiswick in February 2020, the mileage recorded at 36,776. The car has travelled a little over 2,000 miles since.

The same dealer changed the front brake pads in August of this year.

There are no invoices for repairs, the car never having needed any as far as we can tell. BMW/Alpina reliability for you and of course this is a low mileage car.

The MoT is due later this month, but we cannot imagine there will be any untoward issues. The car has had no advisories since 2017, and they were tyre related and dealt with.

What We Think

Alpina cars are still a rare sight on UK roads, so an air of exclusivity is guaranteed. The company takes the finest BMWs and tweaks them and, in our opinion, makes them better. Faster, great looking, yet still with the same easy-care routine that all BMW’s need to keep them working properly.

Convertible cars are always in demand and this B3 S demands no compromises, the folding hard top ensuring warm and cosy winter motoring and easy alfresco adventures at the push of a button when the sun shines.

We expect the car to sell for between £18,000 and £25,000.

BORING, but IMPORTANT: Please note that whilst we at The Market always aim to offer the most descriptive and transparent auction listings available, we cannot claim they are perfect analyses of any of the vehicles for sale. We offer far greater opportunity for bidders to view, or arrange inspections for each vehicle thoroughly prior to bidding than traditional auctions, and we never stop encouraging bidders to take advantage of this. We do take a good look at the vehicles delivered to our premises for sale, but this only results in our unbiased personal observations, not those of a qualified inspector or other professional, or the result of a long test drive.

Also, localised paint repairs are common with collectable and classic cars and if they have been professionally carried out then they may be impossible to detect, even if we see the car in person. So, unless we state otherwise, please assume that any vehicle could have had remedial bodywork at some point in its life.

Additionally, please note that most of the videos on our site have been recorded using simple cameras which often result in 'average' sound quality; in particular, engines and exhausts notes can sound a little different to how they are in reality.

Please note that this is sold as seen and that, as is normal for used goods bought at auction, return policy does not apply. See our FAQs for more info, and feel free to inspect any vehicle as much as you wish.
