Alpina is releasing a new limited edition model that is essentially a more powerful and more appealing re-creation of the BMW 4 Series. This is the new BMW Alpina B4 S Bi-Turbo Edition 99, which would be sold either as a convertible and coupe versions, with deliveries set next year. As its name indicates, only 99 examples of the Edition 99 will be built.
This new BMW Alpina B4 S Biturbo Edition 99 is a limited edition model of the Alpina B4 S, which was derived from the BMW 4 Series. However, the B4 S is even more powerful and more dynamic than the high performance iteration of the 4 Series – the M4 Coupe. The Coupe version of the Edition 99 can be availed either as rear-wheel drive or an all-wheel drive (left-hand drive only). The Convertible model of the Edition, meanwhile, is configured as a rear-wheel drive.
While the 3.0-liter straight-six turbocharged engine of the M4 delivers 431 hp of output, the 3.0-liter turbocharged straight-six mill inside the B4 S offers up to 440 hp (324 kW). It also delivers 442 lb.-ft. (660 Nm) of torque, allowing the B4 S to accelerate from zero to 62 mph (100 km/h) in just 4.2 seconds for the standard rear-wheel-drive configuration, or 3.9 seconds with the all-wheel drive version.
In the BMW Alpina B4 S Biturbo Edition 99, the 3.0-liter turbocharged straight-six engine is tuned to deliver 446 hp (452 PS or 332 kW) of max output, making a bit more powerful than the Alpina B4 S. In the all-wheel drive coupe version of the Edition 99, acceleration from nil to 62 mph (100 km/h) is pegged at 4.3 seconds. The rear-wheel drive version, on the other hand, can complete the sprint in just 3.9 seconds. In terms of top speed, the all-wheel drive coupe version maxes at 190 mph (306 km/h) while its rear-wheel drive counterparty can’t go beyond 188 mph (304 km/h).
As for the convertible version of the BMW Alpina B4 S Biturbo Edition 99, it can go as quick on the sprint as 4.3 seconds and as fast as 189 mph (304 km/h).
To distinguish the BMW Alpina B4 S Biturbo Edition 99 from a regular B4 S, it is fitted with a number of exclusive design features. These include the Alpina badge, the quad-exhaust system, and numbered Edition 99 plaque in the engine bay, a decal by the dashboard as well as the multi-spoke rims.
Interested customers can now place an order for the new BMW Alpina B4 S Biturbo Edition 99, with deliveries to start in the second quarter of 2019.
