2025 BMW Alpina B3 GT & B4 GT pricing for Australia


Alpina Automobiles Australia has announced local specs and pricing for the new BMW Alpina B3 GT and BMW Alpina B4 GT models.

The B3 GT Sedan will open the range from $181,900, followed by the B3 GT Touring wagon from $184,900 and the B4 GT Gran Coupé from $189,900 – all prices excluding on-road costs.

Each new Alpina is driven by a 389kW, 730Nm 3.0-litre inline six-cylinder turbo petrol engine, marking a boost of 25 kW over the standard Alpina 3 and 4 Series engines.

The B3 GT and B4 GT are equipped with a ZF eight-speed Sport-Automatic Transmission, matched to fully variable all-wheel drive and an electronically controlled rear limited slip differential. WLTP-tested fuel economy is rated at 10.5 L/100 km.

Updates to the B3 GT models include a stiffer connection between the rear dampers and the bodyshell, Alpina dome-bulkhead reinforcement struts, and a larger rear stabiliser. Alpina says these changes are aimed at improving driving dynamics and steering precision.

The B4 GT Gran Coupé features new stabilisers with reinforced mounts, revised variable sports steering setup, and active dynamic damping control.

The B4 GT Gran Coupé also includes the new BMW 4 Series headlights.

All three come standard with 20-inch forged wheels in the exclusive GT design colour, Oro Tecnico.

Moving into the cabin, the GT models feature Oro Tecnico stitching on the steering wheel, Alpina Switch-Tronic shift paddles, and black leather piping on the floor and luggage compartment mats. There’s also GT lettering in the door sill trims and sports steering wheel.


The B3 GT and B4 GT are covered by a three-year, unlimited-kilometre warranty with included Roadside Assistance.

All Alpina vehicles can be serviced at official BMW dealerships, and BMW’s Service Inclusive program is available for the range.
