Mercedes-AMG GLC 63 4MATIC+ SUV

For the first time a mid-size SUV is available with the powerful eight-cylinder biturbo in two output variants. The basis for this comes courtesy of the AMG 4.0‑litre V8 engine rated at 350 kW (476 hp) or 375 kW (510 hp) in the GLC 63 S and GLC 63 S Coupé variants (fuel consumption combined: 10.7-10.3 l/100 km; combined CO2 emissions: 244-234 g/km).

Transmission: AMG SPEEDSHIFT MCT 9‑speed sports transmission for extremely short shift and response times.

Drive system: AMG Performance 4MATIC+ variable all-wheel drive. This intelligent system combines the advantages of different drive concepts: the fully variable torque distribution to the front and rear axles ensures optimal traction right up to the physical limit. The driver is also able to rely on high handling stability and a high level of safety under all conditions, in the dry, in the wet or in snow.

AMG DYNAMIC SELECT driving modes: The five AMG DYNAMIC SELECT drive programs of "Comfort", "Sport", "Sport+" and "Individual" allow the driver to extensively influence the characteristics of the GLC 63 4MATIC+.

Suspension: The Performance SUVs feature air spring suspension with adaptive adjustable damping, AMG Performance 4MATIC+ all-wheel drive with fully variable torque distribution, a rear-axle limited-slip differential and also a high-performance braking system.

Alfa Romeo Stelvio Quadrifoglio

ALFA ROMEO Stelvio Quadrifoglio, the new model with many class-topping features, which immediately becomes the new benchmark in the premium compact SUV segment. With its awe-inspiring design, performance and technology, Stelvio Quadrifoglio is the "fastest SUV around the circuit", having clocked the new record for its class on the iconic Nürburgring: 7 minutes 51.7 seconds.

Its performance is outstanding: acceleration from 0 to 100 km/h in just 3.8 seconds and best-in-class top speed of 283 km/h. But the Alfa Romeo sports SUV is also incredibly efficient in terms of emission and fuel consumption, thanks to its electronically controlled cylinder deactivation system and the "sailing" function, available in Advanced Efficiency driving mode.

For the first time, the 510 HP 2.9 V6 Bi-Turbo petrol engine is combined with the innovative Q4 all-wheel drive system, with its guarantees of unbeatable performance, traction, driving pleasure and safety in all situations. What's more, Stelvio Quadrifoglio is equipped with the exclusive AlfaTM Chassis Domain Control unit and is the only SUV in its class to provide differential AlfaTM Active Torque Vectoring as standard. Also standard equipment is the innovative AlfaTM Active Suspension, the system that continually, actively controls the suspensions and shock absorbers. Not to mention that Stelvio Quadrifoglio guarantees impeccable handing and comfort thanks to its suspension layout, with the exclusive AlfaLinkTM technology: up front it has a double wishbone system with semi-virtual steering axis, with a four-and-a-half link Multilink system at the rear. In any situation and at all speeds, driving the Quadrifoglio SUV, with the most direct steering ratio on the market (12.1:1), is natural and instinctive.

Another special feature of Stelvio Quadrifoglio is the innovative electromechanical Integrated Brake System (IBS) - an Alfa Romeo brand exclusive, which first appeared on the Giulia - which has become the new benchmark in terms of both swift response and stopping distance, on any road surface, and weight reduction compared to a conventional braking system. High-performance carbon-ceramic discs will also be available as an optional after the launch.
