The 1M RS is lighter and faster compared to the stock version.
It is designed according Alpha-N's vision of improving the weight on cars, which is critical in racing.
Engine
Alpha-N updated the 3.0 liter 6-cylinder engine through an exhaust system that is specially developed, a new air duct software optimization. As a result, the powertrain can now deliver 410 horsepower which is 70 more than the stock engine.
Performance
In order to complement the powerful engine, Alpha-N installed a high-performance braking system. It includes braided stainless steel lines, 380mm discs and 6 piston calipers. As a result, you get a fast car without compromising safety.
Most of the exterior is made of carbon fiber and thus add to the car's lightness making it nimbler than the stock model. To make the car even lighter, Alpha-N used OZ Superforgiata rims that measure 8.5"x19" and 10.0"x19" in the front and the rear respectively. The additional horsepower provides cutting speed on straightaways, while the lightness brings speed on curves.
Exterior
Focus of the improvements made by Alpha-N is not on the looks, so the 1M RS looks almost the same as the 1M. What is interesting about the 1M RS include its ventilated hood, low spoilers, front fascia, carbon roof, rear fascia diffuser, and luggage lid spoiler that are all made of carbon fiber.
Interior
Alpha-N has not release interior details for the 1M RS. If you want the team to update your BMW 1M, your interior may remain untouched. It is safe to assume that the original interior from the factory version remains.
Pros
If you are after performance, the 1M RS will certainly deliver what you are looking for. The updates are competitive enough to make the BMW 1M worthy during the race. The carbon fiber parts make it extremely light which brings speed virtually anywhere on the track.

Tuner modifications come with a price. Although Alpha-N is yet to release their pricing, we can guess that the improvements are not going to be cheap.
The improvements that Alpha-N made will benefit car enthusiasts. If you are into this sport, the 2012 Alpha-N BMW 1M RS is a great choice.
