For more than three decades, BMW has been offering drivers the combination of a luxury saloon and a fast and sporty car, best known as the M5. While the standard models are exceptionally fast and powerful, it's also the perfect platform for those who want an even sharper experience. The BMW M5 F90, the enhanced BMW M5 from StartLine Motors, is a perfect example of this.
The M5 F90 Series, which debuted in 2017, is powered by the S63 series engine. It is a 4.4-litre displacement, V-shaped, 8-cylinder engine that comes with twin turbos. The manufacturer declares that this engine delivers 590 horsepower and 750 Nm of torque as standard. The car's dynamic performance is also excellent, as illustrated by the following figures: the M5 accelerates from 0 to 100 km/h in just over 3 seconds, and can reach a top speed of 305 km/h with the limiter removed.
But the standard figures can be significantly improved. StartLine Motors has proven this by creating the world's fastest BMW M5 F90 in their workshop. The car, which has been improved in Lithuania, accelerates from 0 to 100 km/h in just 2.5 seconds and reaches 200 km/h in 6.7 seconds. Acceleration from 100 to 200 km/h takes just four seconds and the BMW M50 covers the quarter mile in just 9.53 seconds. These are figures that make it the fastest F90 Series M5 in the world.
Of course, in order to achieve these figures, certain modifications must be made to the car. In this case, this BMW M5, upgraded by StartLine Motors, has had its standard turbines replaced with new ones for greater performance. Improved air intake is achieved by modifying the air intake system, and the standard pipework behind the turbine has been replaced with new, higher-performance elements. Modifications have also been made to the engine internals, replacing the standard pistons and connecting rods with more robust ones. Another improvement carried out by StartLine Motors was the increase in fuel delivery capacity and the installation of a methanol injection system. These modifications have increased the engine's power to 1000 horsepower.
BMW is fitting an eight-speed, ZF-manufactured automatic gearbox to the M5. Its distinctive feature is that it is a torque converter rather than a dual-clutch system. According to the manufacturer, this gearbox is much more reliable and can withstand higher loads, while the shift times are practically the same as those of a double-clutch gearbox. This is also confirmed by StartLine Motors, as no mechanical failures of the gearbox have been observed, even when the engine power is increased, even when the vehicle's transmission is operating at maximum loads.
