The Geneva Motor Show is about a month away but a new report is indicating the Mercedes-AMG GT4 will debut in Switzerland.

Set to battle the Porsche Panamera, the GT4 was previewed by the Mercedes-AMG GT concept which was unveiled at last year’s show. Mercedes has been tight-lipped about the model but AMG CEO Tobias Moers told Car Magazine “I have shown some people the finished car now and they are impressed by how close it is to the show car.”

The model will be based on the MRA platform which underpins an assortment of different vehicles including the E-Class and CLS. The latter model will bear a striking resemblance to the GT4 but Moers isn’t worried as he said “We have a loyal CLS customer base already: it has the perfect combination of style, sportiness and comfort. With our new GT4, the task is all about conquest from other brands.”

To help distance the two models, Mercedes won’t offer a high-performance CLS 63. Instead, the top model will reportedly be the CLS 53 which recently debuted at the North American International Auto Show.

Speaking of engines, we can expect the GT4 to be powered by a twin-turbo 4.0-liter V8. It produces 571 PS (420 kW) and 750 Nm (553 lb-ft) of torque in the E63 and 612 PS (450 kW) and 850 Nm (626 lb-ft) of torque in the E63 S.

Mercedes could also introduce a hybrid variant which uses the same powertrain as the CLS 53. The model has a 3.0-liter six-cylinder engine that produces 435 PS (320 kW) and 520 Nm (383 lb-ft) of torque. It is backed up by an electric motor that contributes an additional 22 PS (16 kW) and 250 Nm (184 lb-ft) of torque. This setup enables the all-wheel drive sedan to accelerate from 0-100 km/h (0-62 mph) in 4.5 seconds before hitting an electronically-limited top speed of 250 km/h (155 mph).
