19 MPG combined is what anyone interested in the 2020 BMW M4 CS should expect. This isn’t a Prius; it’s a machine designed to thrill, to dominate apexes, and to deliver a visceral driving experience. Fuel economy is less a priority and more an accepted compromise for the performance on offer. The M4 CS appeals to a specific buyer: the enthusiast who prioritizes track days and spirited weekend drives over peak efficiency. They’re buying an experience, a pedigree, and a significant dose of adrenaline, and they’re willing to pay, both at the dealership and at the pump.

City and highway performance

The M4 CS isn’t particularly efficient in mixed driving, and its city and highway numbers reflect that. The EPA estimates 17 MPG in city driving, which is understandable given the stop-and-go nature of urban environments and the temptation to exploit the engine’s responsiveness at every opportunity. The highway figure improves to 23 MPG. That’s an attainable number on longer journeys if you resist the urge to constantly dip into the engine’s considerable power reserves for passing maneuvers. Ultimately, both figures serve as a constant reminder that performance comes at a price.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,050 for the 2020 BMW M4 CS. This figure is calculated based on driving 15,000 miles per year, with 45% of those miles driven in the city and 55% on the highway. The EPA also assumes the use of premium gasoline, a necessity for the M4 CS’s high-performance engine, and uses the national average fuel price at the time of calculation. This hefty fuel bill is a direct consequence of the M4 CS’s performance-oriented design and powerful engine.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy can vary significantly depending on driving style and conditions. A heavy foot and frequent track days will undoubtedly result in lower MPG figures than quoted by the EPA. A more conservative driving style, coupled with consistent highway cruising, may yield slightly better results. However, it’s unlikely anyone buys an M4 CS with the intention of achieving peak fuel efficiency. The car’s inherent character encourages, and rewards, spirited driving, which inevitably impacts fuel consumption. Therefore, consider the EPA estimates a best-case scenario, and budget accordingly.

How it compares

The M4 CS exists in a competitive segment, and its fuel economy stacks up as expected. The Audi RS5 Coupe, with its 2.9-liter twin-turbo V6, achieves a slightly better 21 MPG combined. A Mercedes-AMG C63 Coupe, packing a thunderous 4.0-liter V8, clocks in at a comparable 19 MPG combined. Even within the BMW family, the M2 Competition, with its slightly smaller footprint and detuned engine, manages to achieve a respectable 20 MPG combined. Buyers in this segment understand the tradeoffs.

The M4 CS buyer likely cross-shops other high-performance coupes, weighing fuel efficiency against factors like handling prowess, track performance, and brand prestige. For those seeking better MPG, exploring all all Bmw fuel economy data or specific M4 MPG across all years might be worth the time.

Tips to maximize efficiency

The M4 CS doesn’t have inherent efficiency, but there are tactics to mitigate losses. Avoid excessive idling. The turbocharged engine sips fuel even while stationary, so minimize idling, especially in traffic. Turn off the engine when safely possible.

Employ smooth acceleration and braking. Abrupt inputs waste fuel. Anticipate traffic flow and use the engine’s torque to maintain momentum. Gentle throttle application is important.

Maintain optimal tire pressure. Underinflated tires increase rolling resistance, reducing fuel economy. Check tire pressures regularly and inflate to the recommended levels. Consider using nitrogen-filled tires, which maintain pressure more consistently.

Limit track use. While the M4 CS is designed for the track, aggressive driving significantly impacts fuel consumption. Save track days for special occasions or consider a dedicated track car if frequent visits are planned.
