Last summer, we were the first in the Czech Republic to drive a brand new Mercedes-AMG SL. It was the top of the range at the time – a forked eight-cylinder engine with an output of 585 horsepower and 800 newton meters of torque, a hundred in 3.6 seconds and a maximum speed of 315 km/h. Enjoyment? Extremely impressive. Still, someone in the Mercedes sports department thought this open roadster could use a little more spice.

And so the SL 63 S E Performance is presented to the world. As you can probably guess from the name, it is a plug-in hybrid, where the internal combustion engine is assisted by an electric motor. But beware, this is not a car intended for passionate eco-drivers and savers. The battery with a capacity of 6.1 kWh (one of the smallest in plug-in hybrids) serves primarily as a support for the entire system. However, even an open SL in the socket can only manage thirteen electric kilometers without recharging.

Doesn’t that sound like much? So listen to the next numbers. Under the hood, the eight-cylinder heart with a volume of 4.0 liters still beats. That alone delivers 612 horsepower and 850 newton meters. However, it is seconded by an electric motor with an additional 150 kW and 320 newton meters. A systemic result? A great 816 horsepower and up to 1,420 newton meters of torque! With this, the car reaches 100 km/h in 2.9 seconds and has a top speed of 317 km/h.

The center screen can be tilted to prevent the sun from reflecting on it when driving with the roof down.

The entire system is connected to a sports four-wheel drive and a nine-speed AMG Speedshift automatic transmission as standard. It is one of the few electrified cars that does not reach electric registration plates in the Czech Republic. Despite the plug-in hybrid drive, it has table emissions of 175 g CO2/km. However, for EL brands, you need to fit under fifty.

Behind the 20-inch AMG light-alloy wheels is a carbon-ceramic brake system with bronze calipers, the discs of which are even larger than those of the pure combustion sibling. The electrified version can only be recognized from the outside by really careful examination, it is mainly revealed by the cover of the charging port in the rear bumper.

The software of the rear spoiler, which now offers five opening positions, has also been modified. In addition to all-wheel drive, active rear-axle steering is standard, and the SL can also have the AMG Active Ride Control system, which helps reduce body roll during fast cornering. There is also a four-level recuperation system, including the ability to drive the car with a single pedal.

If such a car seems a little exclusive to someone, they can appeal to the Mercedes Manufaktur program, in which the roadster will be adjusted to your specific requirements from the outside and inside. There are countless colors and materials to choose from, everyone will find something to their liking. So just expect that it will be reflected in the already high purchase price, which Mercedes has not yet specified. The price list of current cars ranges from three to five million, depending on the selected version.
