The automotive world is abuzz with the latest from Alpina. With the introduction of the GT badge, the Alpina B3 and B4 are back, stronger and faster, neatly closing the gap to their M3 and M4 counterparts. These aren't just incremental updates; we're talking serious engineering upgrades under the hood and on the chassis.
More Power, More Torque
The centerpiece of the B3 and B4 GT models is the uprated S58 engine, a 3.0-liter twin-turbo inline-six. This powerhouse now delivers 522 hp, just a hair less than the M3 and M4, which peak at 523 hp. Where Alpina truly shines, however, is in torque delivery. Both models churn out a robust 538 lb-ft, outmuscling the M3 and M4's 479 lb-ft. This translates to blisteringly fast acceleration, getting the B3 GT sedan from 0 to 62 mph in just 3.4 seconds, which is faster than the M3 Competition xDrive.
Not Just Faster, But Also Sleeker
But it's not all about brute force. The B3 GT sedan now hits a top speed of 191 mph, while the B3 GT wagon and B4 GT Gran Coupe reach 190 mph. They not only outperform their predecessors but look more aggressive too. The B4 makes the most of facelifted 4-Series Gran Coupe’s LED lights and adds 3D rear lights from the M4 CSL. Meanwhile, the B3 rolls on 20-inch forged wheels that were once exclusive to the B4. Motorsport-style canards, splitters, black diffusers, and tailpipes add to their visual appeal.
Handling the Power
The enhancements don’t stop with power. Chassis upgrades ensure these cars handle the additional force responsibly. The B3 models receive a new rear anti-roll bar and revised shocks, while the B4 benefits from new shocks, reinforced front suspension mounts, and a retuned steering and electronically controlled rear LSD. These changes ensure what is essentially a luxury tourer can handle corners like a pro. And, of course, there are the stylistic elements: small motorsport-style canards and a splitter on the front end, and new gloss black diffusers and black tailpipes at the back.
A Perfect Blend of Luxury and Performance
Alpina’s aim with the B3 and B4 GTs is clear: to balance high-end luxury with gut-punching performance. These latest models integrate effortlessly with BMW’s lineage while carving out their own niche. What sets them apart isn't just the power and torque figures but how the entire package (engine, chassis, and design) comes together harmoniously to deliver a superior driving experience.
As Alpina continues to evolve under BMW's banner, the B3 and B4 GTs are definitive proof that the magic formula is working. Whether you’re in it for the speed, the handling, or the outright opulence, these cars tick all boxes, making them a worthy consideration for any performance car enthusiast.
