Which BMW Has the Most Horsepower?

The yearning for horsepower never fades away whether you’re buying a new car or a used engine. BMW gets it. Thus, it introduced the M8 Coupe and Convertible to satisfy the need for high horsepower among its buyers. The result—a powerful car churning out over 600 HP. BMW M8, till today, is the highest performance model by the Bavarian automaker. If you’re a horsepower nut and wish to buy a powerful car, check out the specs and features of the BMW M8.

BMW M8—Highest Horsepower Ever

To make M8 the highest horsepower producing BMW of all times, the automaker had to come up with a new and power-packed engine that suits the objective. Thus, can the direct-injected, twin-turbo, 4.4-liter V-8 engine that powers all the M8s.

According to BMW, M8 is the most powerful production engine the company has ever made. The engine features cross-bank exhaust manifolds along with mounting the turbochargers inside the V of the engine. This design reduces turbo lag and increases thermal efficiency. Also, there’s a water-to-air intercooler to give more punch to the charge and provide its cooling circuit.

Cooling System

With high horsepower comes the risk of higher heat production as well. To curb that problem, BMW had to upgrade the main cooling system for the engine and turbos. It includes an auxiliary electric pump to circulate coolant to the turbochargers after the engine has been powered down.


M8 coupe and convertible come with an eight-speed M Steptronic which is the only available transmission at the moment. For driver’s convenience, there’s a new selector lever in addition to the paddle shifters.

Secondly, the gearbox has both manual and automatic modes. Moreover, the Drivelogic button allows you to select either comfort or track-oriented shift modes. It also offers predictive shifting. So, the information from the navigation system is coordinated with the transmission controls for what’s ahead.


In M8 Coupe and Convertible, the all-wheel drive is standard. It features an electronically controlled transfer case that splits torque fore and aft. Simultaneously, an Active M differential controls the rear axle.

To allow better sporting handling, the system is biased to the rear. It allows the front wheels to get more powerful when the rears start to slip. BMW offers several driving modes, including 4WD, 4WD Sport (with even greater rear axle bias), and even a 2WD with this car.

Zero to 60

Perhaps the most important metric for BMW enthusiasts is the zero to 60 timing. Interestingly, the M goes from zero to 60 in 3.0 seconds for the coupe and 3.1 seconds for the convertible. That’s the most horsepower and speed BMW seekers have ever seen. The top speed for all the M8s is an electronically limited 155 mph, though that can be increased to 189 mph with the optional M.

Controls inside the M8

The M8 cars have a new setup button on the centre console that can control all the selectable engine, suspension, steering, and Xdrive settings from one location.

Though previous M models were equipped with individual control buttons for selectable modes, the new one comes with the M Mode button on the console. It gives the driver more control over driver assistance systems, the instrument display, and the Head-Up display. Also, the M8 models have Road and Sport settings for instrumentation, while the Competition cars add a Track mode.

Exterior of M8

With such a dynamic powertrain, BMW had to upgrade the exterior of the car as well to compliment the interiors. A few changes include larger openings in the bumper for better cooling, a black chrome kidney grille, high gloss black side mirror housings, rear spoiler, and diffuser.

An optional M Carbon package gives those components in the composite. Icon Adaptive LED headlights with Laser light are standard. The M8 models get a standard carbon-fibre roof, lowering the curb weight and the centre of gravity.

Convertible models have a multi-layer insulated roof that can retract in 15 seconds, and operates at up to 30 mph, so you don’t have to stop to raise or lower the top.

Experience the Power of the BMW M8

Horsepower is at the top of the priority list of most Americans when one sets out to find an engine for sale, a BMW upgrade, or an emergency replacement. BMW M8 successfully does its job by offering 600+ horsepower, which is a first in the history of BMW.

Though M8 satisfies the need for more horsepower, the steep price makes it out of the budget for many. So, if you wish to upgrade your vehicle's horsepower, do so with a cost-effective option.
