The 2018 BMW M4 CS looks spectacular and should be quite an extraordinary sports car. Sadly, it’ll be expensive in North America, costing well over US$ 100,000.

So, what’s the solution if you’re an M enthusiast who wants some extra performance but doesn’t want to break the bank? Well, Alpha-N Performance has a solution.


The company has been on our radar before and has just revealed its latest upgrade package for the M4 that transforms it into a serious CS competitor. The tuning firm has fitted its Stage 1 upgrade to the 3.0-liter twin-turbo straight-six that lifts power to 520 hp, a healthy 66 hp more than the M4 CS and 20 hp more than the GTS.

Alpha-N has fitted fully adjustable Ohlins R/T suspension, 20-inch wheels from HRE and Michelin Pilot Super Sport tires. When you then throw in a carbon fiber rear spoiler, a lip spoiler at the front and Recaro racing seats, you have the recipe for a serious performer.
