Car spotters have traced down this partially disguised Mercedes-AMG GT 73 4‑Door Coupé to the vicinity of the Arctic Circle. The test car may look like the range-topping GT 63 S, but the charging port in the back tells us it is a hybrid.
The first bits of information about the upcoming GT 73 began to emerge in late 2019. The car comes equipped with the same 4.0 AMG V8 engine as much of the rest of the range, assisted by a relatively modest rear-axle mounted electric motor.
The Mercedes-AMG GT Concept the company introduced in Geneva four years ago had 816 PS (806 hp, 600 kW) under the hood and needed less than three seconds to sprint 0-100 km/h (0-62 mph). The mass-produced GT 73 will likely fall short of that kind of performance, but it will still have to surpass its archrival, the Porsche Panamera Turbo S E-Hybrid, which packs 680 PS (671 hp, 500 kW).
On an interesting side note, even the current non-hybrid GT 63 S is faster than the Panamera. With 639 PS (630 hp, 470 kW) and 900 Nm (664 lb-ft) under the hood, it hits 100 km/h in 3.2 seconds, while the Panamera does so in 3.4 s at the least. Furthermore, it ultimately hits 315 km/h (195 mph).
It appears likely that the newcomer to the Mercedes-AMG family will be able to run all-electric for a while, but the range will probably be seriously limited. Just like the Panamera mentioned above, it prioritizes low emission profile over performance.
In accordance with the development strategy previously published by Daimler AG, the GT 73 should be introduced later this year.
