The short-lived SL 73 AMG came out in 1999 and lives up to its name by offering a 7.3-liter engine. The R129-series V12 Roadster was Affalterbach’s most powerful product at launch, offering a whopping 518bhp. and 750 Nm.
Fast-forward to 2021 and Mercedes erases the legendary ’73’ name for the new high-performance AMG family. The three-pointed star took legal action to cement its moniker back in February 2018 when it trademarked a number of “73” models, at least one of which will debut on a production car in the following months. Autocar claims to be well versed in the electrical components of the new era 73 cars.
With an ‘e’ at the end, all 73e models will feature a 4.0-liter V8 twin-turbo engine and an electric motor that borrows heavily from the zero-emission Mercedes EQC crossover and EQV van. It is reported that the electric motor will have a power of up to 201 hp. (150 kW) and an instant torque of 363 Nm.
In combination with a conventional 8-cylinder engine, the Mercedes-AMG 73e with 805 hp. The GT73e should be the first to accelerate from 0 to 100 km / h in less than three seconds on its way to over 322 km / h.
A similar plug-in hybrid is expected to be installed in the new C63e, but with a smaller 2.0-liter 4-cylinder instead of a V8 for a total output that will surpass the 500bhp mark
In conclusion, it is worth mentioning that “G73” and “GLS 73” were also among the brands registered by Mercedes three years ago, but it is unclear if the boxy SUV and full-size luxury SUV will receive an 805-horsepower hybrid powertrain. >
