Overview

The ALPINA XD4 is the coupé SUV companion to the XD3 — sharing the remarkable quad-turbocharged diesel drivetrain with the XD3 but combining it with BMW X4's sporty sloped-roof SUV coupé body style. The XD4 offers a more dynamic visual statement than the XD3 while retaining the same extraordinary technical specification: four turbochargers, 388 hp, 770 Nm, and 270 km/h top speed in a uniquely practical all-wheel-drive package.

ALPINA's philosophy with the XD4 is identical to its approach with the XD3: take BMW's already impressive X4 M40d diesel variant, rework it comprehensively in Buchloe, and produce something definitively better in performance, refinement, and exclusivity. The result is an SUV coupé that accelerates to 100 km/h in 4.5 seconds — quicker than many dedicated hot hatches — while returning approximately 7–8 L/100km in real-world use, a combination that no petrol-powered performance SUV can replicate.

For Azerbaijani buyers who prefer the visual dynamism of a coupé SUV silhouette over a conventional SUV, the XD4 offers the same ALPINA quality and quad-turbo technology as the XD3 in a more distinctive package. The coupé roofline reduces rear headroom slightly compared to the XD3 but otherwise the driving experience and performance credentials are identical. Given the XD4's rarity — produced in even smaller numbers than the XD3 — ownership is an exceptionally exclusive automotive experience.

Frequently Asked Questions

What is the practical difference between the XD3 and XD4?

The XD4 has a sloped coupé roofline which reduces rear headroom by approximately 30–40mm compared to the XD3, and the boot aperture is slightly smaller. Performance, drivetrain, and all mechanical specifications are identical. The choice is purely one of style preference: XD3 for maximum practicality, XD4 for the more dramatic coupé silhouette.

Is the XD4 rarer than the XD3?

Yes. ALPINA produces both the XD3 and XD4 in very small numbers, but the XD4 typically accounts for the smaller proportion of total ALPINA diesel SUV production. Combined, both models are produced in hundreds rather than thousands annually. Finding either in any single market is genuinely rare.

Should You Buy the XD4?

The diesel coupé SUV that nothing else can match — 388 hp, 770 Nm, quad-turbo, hand-built.

The ALPINA XD4 delivers the XD3's extraordinary technical specification in a more visually dramatic coupé SUV package. If you prefer the athletic coupé silhouette over the XD3's conventional roofline, and can accept the slight reduction in rear headroom, the XD4 is an outstanding vehicle — unique in its technology, superlative in its performance, and extraordinary in its rarity.
