Prior to the arrival of the BMW M4 CS, there was a large hole (in each ideology and functionality) between the usual M4 and the super-limited M4 GTS. The base mannequin is a formidable road automobile filled with options and tech, whereas the GTS is a stripped-down, pumped-up observe animal that is not the finest for normal driving. The CS (for Club Sport) fills the void as a lighter, de-contented and extra highly effective automobile than the usual coupe, however does not push issues fairly to the acute of the GTS. The result’s a candy spot within the M4 lineup, giving fans a sharper weekend observe weapon that can be day by day pushed.Simplified M4Unlike the considerably garish GTS, the M4 CS adopts a subtler look that I actually like. Outside of a particular carbon fiber entrance splitter, unique cast V-spoke aluminum wheels and CS badges, it largely appears like a standard M4. That’s not a nasty factor — it is nonetheless a looker with its carbon energy dome hood, fender vents and rear spoiler providing understated perspective.
The CS overhaul inside is a little more drastic. In the title of weight financial savings, carbon-fiber-reinforced plastic door panels trickle down from the GTS that do with out map pockets or armrest door pulls. To shut the doorways after getting in, it’s a must to yank on swanky cloth straps that little question are chargeable for saving a couple of valuable ounces. There’s no middle armrest compartment, both, additional limiting storage choices.One creature consolation spared from the chopping block is three-stage heating for the splendidly snug and supportive M sport seats. The bun heaters are appreciated to counter the cool and moist spring situations we’re coping with within the Midwest. That stated, handbook, single-zone local weather management replaces the dual-zone, automated system present in the usual M4. Even although the automobile’s inside options set is not as sturdy, the CS’ simplified environment do not seem or really feel low cost, with a lot of stitched leather-based and Alcantara sprinkled all through the cabin.
BMW’s iDrive interface handles infotainment duties on an 8.8-inch touchscreen. Standard tech consists of navigation with real-time site visitors info, a satisfactory 12-speaker audio setup, satellite tv for pc radio, Bluetooth and one yr of Apple CarPlay. For energy factors, there is a single 12-volt outlet, one USB on the middle console and… that is it. Safety options embrace parking sensors, a rearview digicam, rain-sensing wipers, and automated LED headlights. Additional tech add-ons are restricted to a head-up show and pace restrict info. Anyone in search of superior security gear is out of luck as a result of issues like adaptive cruise management and ahead collision warning aren’t supplied.

More efficiencyIf you are bemoaning the much less in depth characteristic set, then the M4 CS is not for you. If you are OK with giving up some cabin and tech niceties in trade for additional efficiency, then this limited-edition Bimmer is simply your pace. While the engine does not get the GTS’ loopy water-injection system, the 3.0-liter turbocharged inline six-cylinder does see output improve to 454 horsepower, which bests the M4 by 31 horsepower, and even represents a 10-horsepower improve over the M4 Competition. Torque output jumps to 442 pound-feet — a 36 pound-feet climb over the much less succesful automobiles. Sadly, the M4’s beautiful six-speed handbook transmission is not out there within the CS, leaving the seven-speed dual-clutch automated as the only real alternative. So outfitted, the M4 CS is alleged to hit 60 miles per hour in 3.8 seconds, which matches the M4 Competition, however is faster than the bottom mannequin by one-tenth of a second, and boasts a prime pace of 174 mph. The turbocharged six-cylinder is massaged to push output to 454 horsepower.

Punching up the Sport Plus setting rockets the M4 away from stoplights and out of corners with no turbo lag and gobs of mid-range grunt earlier than truly fizzling out because it approaches the 7,600-rpm redline. Disappointingly, the engine’s exhaust soundtrack nonetheless does not sound all that nice. Drive it arduous and the dual-clutch transmission shortly rips by means of gear adjustments in automated and handbook modes, although cog swaps are harsher than what you may get with Audi’s sensational S-Tronic gearbox.Chassis settings are shared with the Competition mannequin, with sharper tuning for the adaptive dampers, stability management, and torque-vectoring rear differential. Where the CS holds an higher hand is its 3,620-pound curb weight, which is a 65-pound weight reduction from the DCT-equipped M4 Competition. BMW says that this, mixed with the facility hike, helps the CS lap the Nürburgring Nordschleife in 7 minutes and 38 seconds. That’s 14 seconds faster than the run-of-the-mill M4, and simply 10 seconds behind the 493-horsepower, extra hard-core GTS.
I did not make it out to any race tracks to correctly flog the CS, however on the road it turns in instantly, corners flat, and gives tenacious grip on the 255/35R19 entrance and 285/30R20 rear Michelin Pilot Super Sport. Balance is spectacular, permitting for straightforward and managed (and enjoyable) on-throttle rear-end rotation. The out there carbon ceramic brakes present large stopping pressure — as they need to contemplating the $8,150 premium. My main grievance is as soon as once more the M4’s steering: it is aware of inputs, however is unnecessarily heavy and lacks any actual suggestions.The impressively balanced chassis is a ball to toss round.

A bearable dailyAfter driving an M4 Competition with the dual-clutch transmission final yr, I grumbled concerning the gearbox’s horrible efficiency for docile day by day driving. Slow engagement throughout launches and jerky shifts had me urging folks to stay with the usual handbook. Unfortunately, the transmission remains to be its not-so-smooth self, however for some cause I wasn’t as irritated with it this time round. Maybe I am simply changing into accustomed to its subpar conduct.
The stiffer suspension tuning transmits impacts from virtually each bump within the highway into the cabin, even when set to Comfort mode. This automobile gives the identical agency experience because the Competition, however in some way feels extra acceptable on this extra succesful CS.Further serving to with the M4’s cruising credentials is its snug lodging. Plus, the 15.7 cubic toes of trunk house brings respectable cargo carrying functionality, and the EPA-estimated 17 miles per gallon metropolis and 23 mpg freeway gas financial system scores aren’t too shabby, contemplating this automobile’s supposed mission.Manageable experience high quality, roomy inside, and spacious trunk make the CS serviceable for day by day slogs.

Steep worth of admissionSince one in all my important objectives in life can be taking the M4 CS to the observe at any time when doable, my best construct can be an identical to my take a look at automobile. The $550 San Marino Blue metallic paint is a surprising coat on the M4’s exterior pores and skin, and the costly carbon ceramic brakes will let me push it arduous on observe for longer durations with out concern of brake fade. Those two choices take the $104,095 base worth, together with $995 for vacation spot, as much as $112,795. Is the BMW M4 CS actually value the additional loot? The base worth premium between an ordinary, dual-clutch M4 and the CS is $31,050, or $26,300 to leap from an M4 Competition to the limited-edition CS. To BMW fans, that may not be a tall order, particularly contemplating lower than 1,000 of those will come to the US over the subsequent two years. And hey, it is nonetheless a far cry from the $135,000 M4 GTS.
