Mercedes-AMG GT Four-Door Hybrid Confirmed.
The Upcoming performance hybrids from Mercedes AMG will get a stunning E Performance branding, and this rumored GT 73 could make upward of 800 horsepower we have been told.
Mercedes has a lineup of electric vehicles on the way under the EQ name, and its AMG high-performance wing will dabble with them as well. However, Mercedes-AMG also plans to have its entire lineup employ hybrid powertrains soon, including this upcoming electrified version of the GT four-door, likely named the GT73, which will be targeted straight at the 690-hp Porsche Panamera Turbo S E-Hybrid.
AMG hasn't shared any details on the GT73's powertrain yet. Still, we expect it to use a twin-turbocharged 4.0-liter V-8, which makes 630 horsepower in the GT63 S, in conjunction with a more powerful electric motor totaling around 800 horsepower. The 73 will need to have a different type of hybrid system than the lesser GT four-door models (GT 53/GT 43), which use a 3.0-liter inline-six assisted by a small electric motor—and, in the GT53's case, an electric supercharger—that adds no additional peak power. In our testing, the V-8-powered GT63 S hit 60 mph in 2.9 seconds, so it's safe to say the 73 will have an acceleration that borders on reality-warping. As with other GT four-door models, we expect the all-wheel-drive to help more of the power get to the ground.
A "V8 BiTurbo E Performance" badge (pictured above) adorns the front fender, and AMG says that the rest of its upcoming high-performance hybrids will fall under that E Performance name as well. Besides that, the GT73 should look similar to the current top-spec GT63 S with a gloss black front fascia. It's also wearing AMG's black cross-spoke wheels available on the 63 and 63 S.
We'll know more about the Mercedes-AMG GT73 soon, and it should arrive by the end of the year. The current top-of-the-line GT63 S starts at $162,950, so expect the 73 to approach $200,000 or slightly more.
