There is no replacement for displacement.
Alpha-N Performance has tuned and transformed virtually every variant of the outgoing BMW M3 model with an array of modifications. Now, with their latest project, they made the E92 BMW M3 into a cool blue coupe packing a bigger displacement V-8. Named the BT92 4.6, the new M3 packs quite a punch thanks to its naturally aspirated engine and widebody kit that just begs to be driven at full throttle.
Right off the bat, the Alpha-N BT92 4.6 looks like something that’s hiding some serious power. The German tuner installed a full widebody kit on the BT92 4.6 that includes carbon fiber front and rear bumper bars, new side skirts, front-axle mud guards, and rear side panels. To save weight, both the hood and the trunk are made from carbon fiber units, while the wheel house liners are constructed from Kevlar. The rear fascia is noticeably different from the factory model due in part to a new diffuser and a dual, centrally-mounted exhaust system.
Beneath that carbon fiber hood sits a special S65B40 BMW V-8 engine sporting a higher displacement than the factory 4.0 liters. While Alpha-N Performance offers a variety of tuning programs including a supercharger system, the featured blue BT92 4.6 boasts a 4.6-liter displacement thanks to a new crankshaft, pistons, and connecting rods. A new ECU software tune accommodates for the bigger capacity and pushes the naturally aspirated engine to an impressive 490 horsepower and 347 lb-ft. of torque, while kicking the top speed back to over 196 mph. Hiding under the hood also is a special prototype carbon fiber airbox system that has yet to be released to the public.
Putting all of that power to the road is a set of multi-piece S3 wheels with a slick black finish, wearing Hankook Ventus S1 Evo performance tires in a 255/35R 19 and 295/35R 19 setup. The new wheel fitment required Alpha-N to give the BT92 4.6 a new alignment after the installation of a Öhlins Road & Track-running gear to ensure proper stance and handling characteristics.
Inside, Alpha-N Performance gave the GT92 4.6 a cabin that matches the exterior. The Recaro Sportster CS seats, trunk, and other aspects were covered in blue alcantara by the German upholstery specialists at Fischer.
The Alpha-N Performance BT92 4.6 E92 BMW M3 is currently available with a variety of options and engine upgrades ranging from larger displacements to supercharger systems.
