2019 BMW M4 CS Coupe assessment: Larger efficiency with fewer compromises


Previous 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 model is a formidable road automotive filled with options and tech, whereas the GTS is a stripped-down, pumped-up monitor animal that is not the finest for normal driving. The CS (for Membership Sport) fills the void as a lighter, de-contented and extra highly effective automotive than the usual coupe, however would not push issues fairly to the intense of the GTS. The result’s a candy spot within the M4 lineup, giving fanatics a sharper weekend monitor weapon that can be every day pushed.

Simplified M4

Not like the considerably garish GTS, the M4 CS adopts a subtler look that I actually like. Outdoors of a particular carbon fiber entrance splitter, unique cast V-spoke aluminum wheels and CS badges, it largely appears like a regular M4. That is not a foul factor — it is nonetheless a looker with its carbon energy dome hood, fender vents and rear spoiler providing understated angle.

The CS overhaul inside is a little more drastic. Within 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, you must yank on swanky cloth straps that little question are answerable for saving just a few valuable ounces. There is not any heart 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 mentioned, guide, single-zone local weather management replaces the dual-zone, computerized system discovered within the customary M4. Although the automotive’s inside options set is not as strong, the CS’ simplified environment do not seem or really feel low-cost, with a number of stitched leather-based and Alcantara sprinkled all through the cabin.

BMW’s iDrive interface handles infotainment duties on an 8.8-inch touchscreen. Commonplace tech contains navigation with real-time site visitors data, a satisfactory 12-speaker audio setup, satellite tv for pc radio, Bluetooth and one 12 months of Apple CarPlay. For energy factors, there is a single 12-volt outlet, one USB on the middle console and… that is it. Security options embody parking sensors, a rearview digital camera, rain-sensing wipers, and computerized LED headlights. Extra tech add-ons are restricted to a head-up show and pace restrict data. Anybody in search of superior security tools is out of luck as a result of issues like adaptive cruise management and ahead collision warning aren’t provided.

Extra efficiency

If you happen to’re bemoaning the much less intensive function set, then the M4 CS is not for you. If you happen to’re OK with giving up some cabin and tech niceties in trade for additional efficiency, then this limited-edition Bimmer is simply your pace. Whereas the engine would not get the GTS’ loopy water-injection system, the three.0-liter turbocharged inline six-cylinder does see output enhance to 454 horsepower, which bests the M4 by 31 horsepower, and even represents a 10-horsepower enhance over the M4 Competitors. Torque output jumps to 442 pound-feet — a 36 pound-feet climb over the much less succesful vehicles.

Sadly, the M4’s pretty six-speed guide transmission is not accessible within the CS, leaving the seven-speed dual-clutch computerized as the only real alternative. So geared up, the M4 CS is claimed to hit 60 miles per hour in 3.Eight seconds, which matches the M4 Competitors, however is faster than the bottom mannequin by one-tenth of a second, and boasts a high 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 really fizzling out because it approaches the 7,600-rpm redline. Disappointingly, the engine’s exhaust soundtrack nonetheless would not sound all that nice. Drive it onerous and the dual-clutch transmission shortly rips by gear modifications in computerized and guide modes, although cog swaps are harsher than what you will get with Audi‘s sensational S-Tronic gearbox.

Chassis settings are shared with the Competitors mannequin, with sharper tuning for the adaptive dampers, stability management, and torque-vectoring rear differential. The place 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 Competitors. BMW says that this, mixed with the ability hike, helps the CS lap the Nürburgring Nordschleife in 7 minutes and 38 seconds. That is 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 affords tenacious grip on the 255/35R19 entrance and 285/30R20 rear Michelin Pilot Tremendous Sport. Steadiness is spectacular, permitting for straightforward and managed (and enjoyable) on-throttle rear-end rotation. The accessible 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 attentive to inputs, however is unnecessarily heavy and lacks any actual suggestions.

The impressively balanced chassis is a ball to toss round.

A bearable every day

After driving an M4 Competitors with the dual-clutch transmission final 12 months, I grumbled in regards to the gearbox’s horrible efficiency for docile every day driving. Sluggish engagement throughout launches and jerky shifts had me urging individuals to stay with the usual guide. Sadly, the transmission continues to be its not-so-smooth self, however for some motive I wasn’t as irritated with it this time round. Perhaps I am simply changing into accustomed to its subpar habits.

The stiffer suspension tuning transmits impacts from virtually each bump within the street into the cabin, even when set to Consolation mode. This automotive affords the identical agency journey because the Competitors, however one way or the other feels extra acceptable on this extra succesful CS.

Additional 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 economic system rankings aren’t too shabby, contemplating this automotive’s supposed mission.

Manageable journey high quality, roomy inside, and spacious trunk make the CS serviceable for every day slogs.

Steep value of admission

Since certainly one of my essential targets in life could be taking the M4 CS to the monitor at any time when potential, my best construct could be an identical to my take a look at automotive. 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 onerous on monitor for longer intervals with out concern of brake fade. These two choices take the $104,095 base value, together with $995 for vacation spot, as much as $112,795.

Is the BMW M4 CS actually value the additional loot? The bottom value premium between a regular, dual-clutch M4 and the CS is $31,050, or $26,300 to leap from an M4 Competitors to the limited-edition CS. To BMW fanatics, which 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.
