The world's fastest production wagon is getting a new look.
After being forbidden fruit for so many years, high-performance wagons are finally making a comeback in America. For the first time in the model's history, the new Audi RS6 Avant is coming to the US. Alternatively, the Mercedes-AMG E63 Wagon is also sold in the US. If you couldn't already tell, we're big fans of sports wagons because they offer a perfect blend of performance and practicality, despite crossovers continuing to dominate the market.
Sadly, however, there is no BMW M5 wagon and the closest alternative will be forbidden in the US when it goes on sale. What you're looking at is the newly updated Alpina B5 Biturbo Touring, which will be based on the upcoming BMW 5 Series facelift.
It hasn't been officially unveiled by Alpina yet, but our spies have caught a camouflaged prototype undergoing testing for the first time. As we've seen on recent 5 Series facelift prototypes, the Alpina B5 BiTurbo Touring's styling has been updated with slimmer headlights, a wider grille, and new rear lights.
Compared to other Alpina models, however, the facelifted B5 looks more aggressive thanks to a new front bumper sporting some large air intakes. Elsewhere, Alpina has added a set of multi-spoke wheels and quad exhaust pipes. Clearly, this is going to be a very stylish wagon, but the upgrades suggest Alpina's new models could have sportier look.
Alternatively, the sporty look could be reserved for the B5 Biturbo and the diesel-powered D5 S could have more traditional styling. Either way, there's very little chance of Alpina's new M5 wagon being sold in the US.
Fewer changes are likely to be found under the hood. Technical specifications haven't been confirmed yet, but the updated Alpina B5 Biturbo Touring is expected to retain the previous model's 4.4-liter V8 twin-turbo engine that generates 608 horsepower and 590 lb-ft of torque. This enables the performance wagon to sprint from 0-62 mph in just 3.5 seconds and reach a top speed of over 200 mph, making it the fastest production wagon in the world. Not that we're jealous or anything.
