It's difficult enough to make a sports car with great performance, but to take a proper Formula 1 powertrain and, with little compromise, transplant it into something reliable, durable and practical enough for use on normal roads is a truly astonishing feat.
The results are some insane performance figures- an engine that reaches 11,000 (!) RPM coupled with a lag-free electric turbocharger, acceleration from 0-200 km/h in under 6 seconds (which, by the way, is faster than what many performance cars today take to reach 100 km/h) and a 1.6L petrol engine with 4 electric motors producing over 735 kW of power. The 25 km of electric-only range is a handy bonus as well.
The exterior design may not bear much resemblance to the rest of the Mercedes family, but with much of it presumably being dictated by aerodynamics, the fact that it looks decent at all is an achievement in itself.
Overall, a remarkable vehicle that demonstrates the prowess of the engineers and designers at Mercedes.
