With the BMW 5 Series on its way out, tuning firm Alpina is closing the B5 in relation to a more powerful limited edition model.
The 2023 Alpina B5 GT will be available in both sedan and Touring wagon body styles and will be limited to just 250 units worldwide.
We don’t expect to see anything here, with Alpina discontinuing the B5 locally in 2020.
Under the bonnet is a 4.4-liter twin-turbo V8 engine which Alpina claims is its most powerful engine to date, pumps out 466kW power and 850Nm of torque.
That’s an extra 6kW and 100Nm over the BMW M5 Competition, and 19kW and 50Nm over the regular B5.
Alpina says the extra power comes from flow-optimized air intakes and silencers as well as updates to the engine software.
The extra engine performance will take the B5 GT sedan from 0 to 100 km/h in just 3.4 seconds, while the Touring will take 3.6 seconds. The top speed is 330km/h for the sedan and 322km/h for the Touring.
Like the regular B5, drive is sent through a ZF eight-speed automatic transmission to all four wheels.
Alpina claims the B5 GT has better handling thanks to optimized roll support on the rear axle and dome bulkhead struts for front-end stability, as well as a slightly lower ride height that lowers the center of gravity in the Touring.
The B5 GT will run on the latest version of 20-inch, 20-spoke Alpina wheels, featuring B5 GT lettering and wrapped in Pirelli P Zero tires.
Behind the alloy wheels are lightweight Brembo brake discs measuring 395mm at the front and 398mm at the rear, and highly heat-resistant brake pads provide enhanced pedal feedback.
Although the exterior of the B5 GT is not significantly different from the regular B5, there are aerodynamic changes including a sub-plane and a partial front splitter on the front spoiler for better downforce.
There is an Alpina twin sports exhaust system with a central silencer configuration and a glossy black finish thanks to a titanium nitride coating.
Exterior colors include standard Alpina Blue and Alpina Green, as well as special colors Petrol Mica, British Racing Verde, Chalk, Imola Red, Daytona Violet and Arctic Race Blue.
Examples finished in Marron Volciano, Blue Matt and Green Matt are also available with traditional Alpina Deco side stripes.
The standard interior includes Nappa leather upholstery in several colors, with embroidered B5 GT lettering on the headrests and floor mats, as well as a heated steering wheel with aluminum paddle shifters, and Walnut Anthracite fine wood trim throughout the cabin.
A full leather Merino interior is optional, or buyers can choose a bespoke naturally tanned Lavalina leather interior created exclusively by Alpina interior saddlery. This option will only be available in limited numbers.
Bespoke upholstery options also include sports seats with flared side bolsters, finished in Black Dakota leather with Black Alcantara center seats and blue accents.
Each B5 GT will be fitted with a stainless steel production plate on both the center console and engine, stating the unique production number of the limited edition model.
Alpina has confirmed German pricing for the B5 GT, with the sedan priced at €145,500 (A$225,000) and the Touring priced at €148,500 (A$230,000).
The tuning firm has started taking orders for the B5 GT and deliveries are expected to begin in July 2023.
