2023 Alpina B3 price and specs

Tuning firm Alpina has revealed its fettled version of the updated BMW 3 Series, the B3, along with its diesel D3 S counterpart not sold here.

The B3 sedan and Touring wagon will be here before the end of 2022, with pricing kicking off at $152,900 before on-roads.

Like the 3 Series update, there’s a revised interior with new technology, while outside there are detail changes compared to the existing B3.

The Buchloe-based tuning firm has also given the B3 some more oomph courtesy of a new exhaust system and new engine software.

Pricing

• 2022 Alpina B3 sedan: $152,900
• 2022 Alpina B3 Touring: $155,900

All prices exclude on-road costs.

Engine

The 3.0-litre twin-turbocharged inline six-cylinder engine in the B3 produces 364kW of power (at 5000-7000rpm) and 730Nm of torque (at 2500-4500rpm).

That’s up 24kW and 30Nm on the outgoing model, with peak power now available 500rpm lower.

Those outputs also align it with the recently-revealed B4 Gran Coupe, and in Touring guise it has the same 0-100km/h sprint time of 3.7 seconds.

The B3 sedan is quicker still with a 3.6-second sprint time.

All B3 models feature an eight-speed torque-converter automatic transmission and rear-biased xDrive all-wheel drive.

Fuel Economy

Alpina claims combined cycle (WLTP) fuel consumption of 10.1L/100km.

Dimensions

The Alpina B3 measures 4719mm long, 1827mm wide and 1440mm tall, on a 2851mm wheelbase in sedan guise. Claimed boot space is 480L.

The Touring has a 2mm lower roofline, and has a claimed boot space of between 500L and 1510L depending on whether the seats are folded.

Safety

The Alpina B3 hasn’t been crash tested by Euro NCAP or ANCAP, but the BMW 3 Series on which it’s based has a five-star rating based on testing carried out in 2019.

It scored 97 per cent for adult occupant protection, 87 per cent for child occupant protection, 87 per cent for vulnerable road user protection, and 77 per cent for safety assist.
