The CarBahn BMW M4 Competition xDrive is a masterpiece of engineering, crafted by the renowned Steve Dinan and his team. This heavily modified machine transforms the already potent BMW M4 into a vehicle that’s as exhilarating as it is capable, rivalling top-tier sports cars with its finely tuned performance and innovative enhancements. It’s not just a car—it’s an experience that redefines what a BMW can do.

Under the hood, CarBahn’s Signature package elevates the S58 3.0-litre twin-turbo engine to produce an astounding 735 horsepower and 668 lb-ft of torque. This is achieved through meticulous upgrades, including refined engine software, a high-efficiency intercooler, a cold air intake, and a custom exhaust system. The result is an explosive driving force that delivers power effortlessly, whether you’re conquering canyon roads or tearing through a track.

The suspension system has been reworked for precision and control. Adjustable coil-over dampers, monoball bushings, anti-roll bars, and a carbon-fibre strut brace come together to ensure exceptional handling and stability. To complement the performance upgrades, the package includes a suite of carbon-fibre elements for aerodynamic efficiency, from a striking grille to a sleek rear spoiler, all contributing to the car’s commanding presence and improved dynamics.
On the road, the CarBahn M4’s personality shifts depending on its environment. Urban settings reveal a suspension tuned for motorsports, with every detail fine-tuned for performance. The car comes alive on a track or in the mountains, providing a thrilling and responsive driving experience. Its ability to balance agility and power creates a sense of confidence and control, allowing drivers to push limits without hesitation.
Performance figures speak volumes. The CarBahn M4 rockets from 0 to 60 mph in just 2.9 seconds and completes the quarter mile in 11 seconds flat. Around corners, it delivers 1.16 g of lateral grip, matching the prowess of supercars. Its brakes are equally impressive, bringing the car to a halt from 60 mph in just 89 feet—a testament to its engineering excellence. The CarBahn M4 is built to dominate, whether on a winding road or a competitive circuit.
Steve Dinan and the CarBahn team have created something remarkable with the M4 Competition xDrive. It’s not just about power or speed—it’s about crafting a machine that delivers a pure, unfiltered connection between driver and road.
