It will be the final sendoff for the F80 M3.
The BMW M4 CS (pictured below) is the closest most of us will actually get to the hardcore GTS version. With a 460-horsepower engine and a 0-100 kilometre per hour time of just 3.9 seconds, it’s a healthy upgrade over the lower-level M4. Now, Bimmer faithful may be able to getting the same treatment with the four-door M3.
According to German publication Bimmer Today, the new M3 CS will be "the most powerful M3 of all time," when it shows up sometime in 2018. Power will come from the same 3.0-litre biturbo six-cylinder engine, but in this application it will be offered with as much as 460 hp on tap.
Like the M4 CS and GTS before it, the M3 CS will also go through a major weight loss treatment to make it more suited for the track – currently the sedan tips the scales at 1,605 kilograms (3,540 pounds). A carbon fibre hood, a new front splitter, a rear diffuser, and some added vents on the grille will be among the most significant upgrades. New wheels and tires will also be fitted.
With all these upgrades equipped, the publication suggests that the M3 CS will be able to lap the Nurburgring in less than 7:40 while wearing a set of super sticky Michelin Pilot Sport Cup 2 tires. For reference, the Alfa Romeo Giulia currently holds the four-door Nurburgring lap record with a time of 7:32.
Of course, we’re taking these reports with a grain of salt. If and when the new M3 CS does make its eventual debut, it won’t be until at least spring of 2018. The M3 CS will be the last variation of the current F80 model before BMW replaces it altogether.
