Mercedes-AMG made a giant splash on the Frankfurt Motor Present final 12 months with the revealing of its Challenge One idea. Quick ahead one other 12 months and Affalterbach continues to be working onerous to deliver the ferocious System 1-engined hypercar to market, nevertheless it’s launched a number of official “spyshots” to whet our appetites. The corporate stated that it has spent a whole lot of hours to get the race-spec hybrid powertrain to be dependable sufficient for the street, simulating the world’s hardest tracks on the dynos of its Excessive Efficiency Powertrains (HPP) division in Brixworth – the identical firm that builds the F1 staff’s championship-winning engines. Since then, the ability unit has been put in on the primary prototypes, which at the moment are being run on a “secret take a look at floor” in England (appears just like the Millbrook Proving Floor to us). The automobile seen right here is lacking its lights and some fittings – most notably the “bargeboards” aft of the entrance wheels – however the low slung bodywork with the huge entrance air intakes and LMP-style dorsal fin is as per the present automobile. The info and figures stay hypothetical for now, however right here’s what we all know. Beneath that fin is a 1.6 litre turbocharged and direct-injected V6 instantly from an F1 automobile (on this case the 2016 F1 W07 Hybrid that took Nico Rosberg to his solely world title), with pneumatic valve springs to allow it to spin at as much as 11,000 rpm.

Whereas stratospheric for a street automobile, it’s considerably decrease than the race automobile’s 15,000 rpm restrict, to increase the engine’s life and permit the usage of business RON 98 gasoline. Additionally carried over from F1 is the break up turbocharger that locations the turbine and compressor on reverse ends of the engine, related by a shaft – this allows the compressed air to be cooler as it’s separated from the warmer exhaust. Fitted to the engine are two electrical motor-generator items. The MGU-H (for warmth), which produces round 90 kW (120 hp), scavenges vitality from the exhaust to drive the compressor, thereby decreasing turbo lag – Mercedes-AMG claims the engine’s response betters that of a naturally-aspirated V8. A second motor, MGU-Okay (for kinetic), is related to the crankshaft and recuperates as much as 80% of the automobile’s kinetic vitality below braking. When known as for, it delivers 120 kW (161 hp) of additional energy, pushing output on the rear wheels alone to over 670 hp – routed via a brand new eight-speed automated handbook gearbox. The engine’s thermal effectivity of over 40% betters the manufacturing document set by the newest Toyota Prius. That’s not all – one other pair of 120 kW electrical motors sit on the entrance to supply all-wheel drive and torque vectoring on the entrance axle. All in all, the headline whole energy determine stands at over 1,000 hp, propelling the Challenge One from zero to 200 km/h in below six seconds and onwards to a prime pace of over 350 km/h. The automobile can also be able to an all-electric vary of 25 km because of the 2 entrance motors, the MGU-Okay and a lithium-ion battery pack aft of the entrance wheels. The latter is positioned in the identical place as on the F1 automobile and makes use of the identical cells, however is bigger to supply the additional vitality wanted for street use. There’s nonetheless a standard 12-volt electrical system, however the hybrid powertrain runs at 800 volts as an alternative of the same old 400 volts. Except for the engine and 4 electrical motors, the Challenge One additionally includes a carbon fibre monocoque, with the engine and transmission sharing load-bearing duties à la Ferrari F50. The multilink suspension options pushrod dampers mounted transversely, stopping roll even throughout very fast path adjustments, with out leading to an uncomfortable journey. Carbon ceramic brakes come as customary.

Cast aluminium alloy wheels measure 19 inches on the entrance and 20 inches on the again, wrapped in 285/35-section entrance and 335/20-section rear Michelin Pilot Sport Cup 2 tyres designed particularly for the Challenge One. The multi-spoke rollers carry carbon fibre covers with air flow slats throughout. With all this efficiency, AMG boss Tobias Moers stated that it’s “cheap to take a position” that the corporate can be aiming for a lap document, though it’s unlikely to problem for the outright document provided that Porsche has just lately set the marker of a blistering 5 minutes 19.6 seconds with the purpose-built 919 Hybrid Evo. The Porsche 911 GT2 RS‘s 6 minutes 47 seconds manufacturing automobile document is a extra probably goal. The manufacturing mannequin is purported slated for a 275-unit run – and even with a rumoured €2.17 million (RM10.9 million) price ticket, all of them are reportedly bought out.
