BMW revealed changes to the M4 lineup at the Shanghai Auto Show; the company also gave show goers a look at the M4 CS, the penultimate model in the series. Lodged between the M4 Coupe outfitted with the Competition Package, and the intense M4 GTS, the CS model M4 presents prospective buyers with one more ready-to-wear variation.
The M4 CS—‘CS’ for ‘Competition Sport’, by the way—is a special edition vehicle, and will be produced in a limited production run at BMW’s historic manufacturing facility in Munich.
The M4 CS takes the 3.0L twin-turbo engine and squeezes an additional ten horsepower from it, in contrast with the M4 Competition Package car; that’s about 40HP under the GTS, but allowances have to be made, and 460 will certainly provide very respectable growl and G-force. BMW’s press release details the numbers as 3.8 seconds to sixty, with the CS topping out at 174MPH (electronically limited). The gearbox is the same M-series seven-speed, dual clutch Drivelogic transmission. Full manual is not an option, but there are paddles on the wheel, and the automatic keeps fuel economy at an attractive 28MPG.
The M4 CS is really distinguished from the Competition Package model by its own front splitter design—carbon fiber, natch—trio of air intakes, and the inclusion of the GTS model’s rear diffuser. The CS also gets a Gurney spoiler unique to the model, carbon fiber as well, and hood and bonnet of carbon-fiber reinforced plastic. And the model tunes the adaptive suspension, active differential, and electromechanical steering systems especially for the model. A Sport+ preset driving mode allows the CS into GTS track-driving territory.
Cabin cosmetics are also changed, as expected. The M4 CS cars receive upholstery in leather and Alcantara, and the GTS model’s fabric doors and door panels. Model recognition for the CS is provided for both interior and exterior.
European pricing for the model exchanges to about $128K USD; the model will reach U.S. shores next year.
