BMW Super Bild: Alpina B7 Turbo

BMW Super Bild: Alpina B7 Turbo

A lot has been made recently about the new Alpina B7 BiTurbo , BMWBlog.com even  spent some time with it last year.  As amazing as the new Alpina B7 is I’ve had the privilege of flogging it myself, yet I still find myself pining for the original B7 Turbo. This the subject of this week’s Super Bild.

Today’s Super Bild is owned by Ivar Lae Pedersen and is a stunning example of the E28 based road missile, finished in a custom copper metallic. A paint selected for this particular custom build. A few pictures of Ivar’s build are included below.

Although Ivar’s B7 is built on the original E24 chassis from 1984 with the later upgraded wheels, the later chassis cars dubbed “B7 Turbo Kat” where Kat stood for Catalytic converter were built on the E28 M5 chassis. In spite of the then introduced smog regulations, the later version B7 mustered a very impressive 320 bhp. For comparison purposes, the Porsche 930Turbo for that same year made 300 bhp, no wonder the Alpina B7 Turbo was the fastest sedan in the world at the time.

The engine was based on BMW´s 3.5 liter unit, which in standard version produced 218 bhp. Alpina breathed new life into the engine such as a reprogrammed Motronic system, a modified cylinder-head, lighter Mahle-pistons, a new camshaft, a special exhaust manifold and of course a KKK K27 turbocharger. The later engines had higher compression than the original B7 Turbo so Alpina had decreased the turbo boost to 0.7 bar, because they didn’t want the B7 to have more than 300 bhp. And that´s exactly what it had; 300 bhp and a torque of 501 Nm. The subject of today’s Super Bild being the later car makes 320 bhp. The gearbox was a five-speed sourced from Getrag.

The B7 Turbo had the excellent Alpina-Bilstein suspension with progressive springs and gas-pressure dampers. The brakes were more powerful thanks to Girling discs all-around, ventilated at the front. The wheels were 16 inches with 205/55 tires at the front and 225/50 tires at the rear.

The B7 had all of the usual Alpina interior changes such as Recaro seats with Alpina upholstery, leather steering-wheel, gear knob, new instruments and so on. The visual changes included a deep front spoiler, rear spoiler and the signature radial spoke wheels.

Depending on what year the car was manufactured Alpina had claimed different 0-100 km/h times. When Auto Motor und Sport tested the B7 Turbo Kat it accelerated from 0-100 km/h in 6.1 seconds, 0-160 km/h in 12.8 seconds and had a top speed of 265 km/h. But when the Swedish magazine Teknikens Värld tested the B7 Turbo it accelerated from 0-100 km/h in an amazing 4.8 seconds, 0-200 km/h in around 17 seconds and had a top speed of 270 km/h.
