BMW Just Unveiled the New Alpina B3 and B4 GT - Here's Why They're the Ultimate Performance Sedans
If you're a connoisseur of refined automotive performance, then the latest news from Alpina is bound to excite you. While BMW's own M machines grab headlines with their aggressive styling and raw power, Alpina has always walked a more sophisticated path, offering high-performance enhancements without the brash, in-your-face aesthetic. Now, the legendary tuning house has taken the wraps off the 2025 versions of their B3 and B4, backed with the glittering 'GT' badge.
Power and Precision
For quite some time, Alpina has had the high-performing B3 and B4 in their lineup, powered by a potent twin-turbocharged 3.0-liter inline-6 engine. The same engine seen in BMW's M3 and M4 models is tuned to deliver 488 horsepower. However, with the new GT models, Alpina has managed to dial this power up to a thunderous 522 hp, thanks to finely-tuned engine recalibration. This recalibration isn't just for show; it represents a meticulous engineering marvel that delivers better performance without compromising the car's inherent sophistication.
Transmission and Drivetrain
To handle this bump in power, the standard 8-speed automatic gearbox has undergone a recalibration specifically catering to the GT models. The best part? No matter the configuration, you get all-wheel drive as standard, ensuring that all four tires effectively grip the asphalt, translating the enhanced power into breathtaking speed and control.
Speed and Agility
The results are nothing short of spectacular. The B3 GT sedan, as well as the Touring wagon, can sprint from 0-62 mph in a blistering 3.4 seconds, while the Gran Coupe variant of the B4 GT clocks in at 3.5 seconds. And if straight-line speed is your game, you'll be thrilled to hear that these masterpieces cap out at a bone-chilling 191 mph.
Designed for Sophistication
Unlike many performance-focused cars that flaunt their speed with aggressive stylistic choices, Alpina's approach remains beautifully restrained. Expect subtle upgrades like a front lip spoiler, refined rear fascia, and the iconic quad-exhaust tip design that makes Alpina's creations instantly recognizable without screaming for attention. The fresh 20-inch wheels and custom badging further elevate the exterior, while the interior sees various Alpina logos seamlessly integrated into digital screens and the infotainment system.
Based on 2025 Updates
Both the B3 GT and B4 GT are crafted on the updated platforms of the 2025 3-Series and 4-Series models. This includes the new 48-volt mild-hybrid systems in non-M variants, adding another layer of sophistication and efficiency. Minor chassis tweaks and upgraded interior options ensure that even the base models are anything but basic.
The Fine Print
If you're dreaming of parking one of these high-performance beauties in your driveway in the U.S., you might be in for disappointment. True to their exclusive nature, Alpina’s B3 and B4 models, including these new GT versions, are not slated for U.S. sales anytime soon. For now, they remain a tantalizing fantasy for American enthusiasts.
