Ultra-rare Alpina B3 GT3 Available at Silverstone Auctions
The E90 M3 brought with it a change in engine layout for the first time in since the E36 was introduced with a straight-six. Its four-lire V8 produced 414bhp at a lofty 8,300rpm – or in E92 GTS trim 444bhp. Propelling the car through at DCT gearbox, the standard car could hit 60mph in 4.6 seconds or 4.4 in the GTS.
BMWs official tuner, Alpina, has never been shy of going toe-to-toe with the standard cars and in the Alpina B3 GT3 it produced a car that was a true rival to the E92 M3 GTS. It did, however, produce them in tiny numbers; just 99 in total of which only four were made in right hand drive. So the fact that Silverstone Auctions is offering a 2014 B3 GT3 in right hand drive at its Salon Privè Sale on September 3rd makes this something of a rare opportunity.
As with any Alpina the differences from the BMW equivalent are thorough across the engine, body and chassis. Alpina’s well regarded twin turbo, three-litre straight six engine sits up front and is tuned to produce 402bhp and 398lb ft of torque. This enables the B3 GT3 to sprint to 60mph in 4.5 seconds. The power is transferred to the road through a six-speed automatic gearbox and a Drexler limited slip differential. Top speed is 186mph.
The suspension has been completely reworked with adjustable coilover suspension which not only allows the driver to tune ride height but also offer 12-way compression and 18-way rebound settings. Pre-determined settings that get progressively firmer help the driver gain the best from the car without requiring too much technical knowledge, thankfully. Braking is provided by 380mm discs and six-pot calipers up front with slightly smaller discs on the rear.
Alpina also managed to shed some weight compared to the M3, coming in slightly under the M3’s 1,600kg. This is helped by the brand’s iconic wheels which come in at under 10kg per corner, and a titanium exhaust from Akrapovic, which weighs 11kg less than that on the M3.
This particular car is a 2014 Alpina B3 GT3, number 74 of the 99 examples built; its first and only owner has covered just 4,000 miles in it. Spec wise, said owner ticked the boxes for the Comfort Pack (which includes the Professional satellite navigation system) and a Digital Race Display system. Last serviced in May 2016 it’s about as near to showroom as you can get.
One of the most attractive things about this Alpina B3 GT3 is its price, guided at £50,000 – £60,000. In context, an M3 GTS (to which the Alpina is a viable rival) would set you back over £100,000 and 36 more examples of that car were produced. From that perspective, this could be a very wise investment by whoever buys it!
