Typewriters or fast cars, this was the choice for young Burkard, son of the German Bovensiepen family that by trade made typewriters. This was back in 1960s when, in the face of a disapproving German Automotive manufacturing industry, Burkard established Alpina, a BMW tuning business.
Tinkering with carburettors and cylinder heads Burkard had success with the then current BMW 1500 range in 1963, and by 1965 Alpina had a turnover of 200k DM and seven employees.
Alpina really established itself from 1968 with a hugely successful racing career that spanned nine winning years, the highlight being 1970 in which Alpina team cars won the electrifying European touring car championship, the German hill climbing championship, and the prestigious Spa 24 hour race. Legendary race drivers Derek Bell, Niki Lauda, and Hans Stuck have all raced Alpina prepared BMW 2002s and CS coupes during their racing careers.
Since 1983 Alpina has been recognised by the German Federal Ministry of Transport as an automobile manufacturer, thus Alpina-built cars are branded and registered as Alpina instead of BMW, although an Alpina can be bought and serviced at select BMW dealerships and covered if there is a warranty issue.
In November 1981 the E28 B9 was introduced, which used a modified 3.5-litre M30 engine that had a reprogrammed Motronic ECU, high-compression Mahle pistons, an aggressive 268 degree camshaft, and a modified cylinder head. The result of these upgrades was 240hp, a substantial increase over the standard engine. At the corners were larger 284mm ventilated disc brakes and Alpina Bilstein gas-pressure suspension. The B9 would accelerate from 0-60 in 6.7 seconds and reach a top speed of 151mph. In 1985 the B9 was renamed the B10 and received a new 3.5-litre engine taken from the B6 that produced 261hp. It is understood that around 500 B9s were produced.

The menacing exterior is finished with slim Alpina decals in gold that run the car’s length and along the front air dam. At the rear the boot lid sports a purposeful Alpina spoiler and Alpina badging; an additional B9 3.5 badge is mounted on the front grille. The bodywork is in great condition overall, presenting with only a handful of light blemishes to the paint. All of the bumpers and trim appear in fine fettle, boasting no scuffs or signs of major wear.
The desirable Alpina upholstery is a welcome sight upon entry. The sports seats present well in their original velour, with no unsightly rips or marks to be found; the classic Alpina stripes are still well defined and the bolsters are damage-free. The leather-bound Momo steering wheel presents as new and there is only light wear to the classic wooden gearknob. The numbered plaque is still in place on the centre console.
ENGINE & TRANSMISSION
At the heart of this E28 lies the Alpina-tuned 3.5-litre straight six. The M30 engine is similar to that of the BMW 635CSi although for the B9 it was extensively modified by Alpina, who replaced the cylinder head, pistons, camshaft, and modified the Bosch Motronic ECU. This resulted in 240hp and a 0-60 time of just 6.7 seconds.
The original engine is correctly stamped with an additional four-digit Alpina production number. The under-bonnet area is in good order throughout with no signs of accident damage or poor repair. A full service was carried out in 2017; more recently the diff has been re-commissioned.
WHEELS, TYRES & BRAKES
The B9 has a purposeful stance and a stunning profile. The 16-inch open lug Alpina alloys really set the car off and present in perfect condition having been refurbished to the highest standard by Lepsons. The Bridgestone tyres are good all round and the brakes do a great job of pulling the car up quickly and in a straight line.
Production of this rare B9 3.5 was completed in April 1983. The car was originally supplied to Germany and was sold through a BMW dealer near Düsseldorf. The purchase price was nearly 57k DM with an additional 6k DM of factory options. These details are confirmed by official documentation from Alpina, which includes copies of the original sales invoice and factory build sheet.
At two years old the B9 was exported to Japan where it resided for the next thirty-two years. It was then imported by 4 Star and subsequently prepared for sale. Following some light re-commissioning work the car was UK-registered and supplied to its new keeper. The E28 is now offered for sale once again, ready to be driven and enjoyed by the next owner for many years to come.
