The BMW M3 CS is so dialed in, you may think that it's operating on instinct.

From the October 2023 issue of Car and Driver.

Why wait for Elon Musk's ethically dubious Neuralink? If you want to feel telepathically connected to something, buy a BMW M3 CS. Behind its David Cronenberg body-horror visage is a lighter, stronger M3 that responds with such immediacy that it's as if there's a cable from the USB port jammed into your brainstem.

The M3 CS's twin-turbo 3.0-liter inline-six makes 543 horsepower, 40 more than the M3 Competition and 70 more than the standard model. Torque remains unchanged from the Comp at 479 pound-feet. Unlike the equally track-focused M4 CSL, the CS is all-wheel drive, though the system can decouple the front axle to enable rear-drive heroics. An eight-speed automatic is the only transmission offered because it's quicker than a human.

Carbon-fiber-reinforced plastic carries the weight (or lack thereof) in the M3 CS. BMW uses it liberally, from the roof to the cabin trim. The cabin also sheds weight by replacing the center armrest with an awkward stub of a thing that's ergonomically frustrating in daily driving. BMW's lightweight (and, if you're thick of thigh, cramped) carbon bucket seats are standard. All of this contributes to a curb weight of 3890 pounds, 39 less than the M3 Competition xDrive we tested and 310 more than the M4 CSL.

Then again, daily driving is clearly not BMW's goal for this car. The M3 CS defaults to its smoothest suspension setting but can't negate the impact harshness from the thin-sidewall Michelin Pilot Sport Cup 2 R tires. Switch to a firmer setting anywhere but an obsidian-smooth track, and you'll regret it. The steering is quick and never relaxed on-center, riding a fine line between telepathic and twitchy. It's a rowdy point-and-shoot affair.

The M3 CS's liposuction pays off. With a 2.7-second 60-mph time, it's a tenth quicker than the M3 Competition xDrive and six-tenths quicker than the CSL (thank you, all-wheel-drive traction). It crosses the quarter in 10.7 seconds at 129 mph, so you can brag that you own a 10-second car. Around the skidpad, there's more understeer than expected from the Cup 2 Rs. An average of 1.06 g's is quite low for a track tire and barely exceeds the Competition xDrive's result. But the sticky tires and an $8500 carbon-ceramic brake package keep deceleration nice and tidy, stopping the car from 70 mph in just 146 feet.

You may have noticed that the M3 CS only marginally outperforms the M3 Competition xDrive, despite a starting price that's $34,400 higher. If you're chasing every tenth on the track, that could be worth it. But if you're just peacocking at the office, we'd stick with the Competition and save a bit on physical therapy.
