Hossam Taibi Posted January 2, 2019 Share Posted January 2, 2019 The power output of Mercedes-AMG upcoming A45 appears to have been revealed accidentally by a German insurance website. HUK24, an online insurance provider, has stored powertrain specs in a drop-down list for the new range-topping A-Class, examples of which were registered for road use in Germany in December. The details, although unconfirmed officially, reveal that there will be two different power outputs from the car's 2.0-litre turbocharged petrol engine. The 'base' model will produce 387PS (382bhp), while the flagship S variant makes 421PS (415bhp). Both will put their power down through all four-wheels, and are set to go on sale later this year. The output of the standard model is already in excess of the 370bhp produced by the outgoing A45, with the top-spec car a full 45bhp more powerful. That should translate to 0-62mph of around four-seconds, and possibly less. The video, which the German firm has called 'Not another Christmas video', showed an A45 in a bold multi-coloured disguise livery lapping a test track in Germany, and showed the car performing a series of powerslides While few official details of the range-topping A-Class have been revealed, Autocar has previously learned that it is set to have the highest specific output for a production engine in the world, eclipsing even the McLaren Senna's 789bhp V8. AMG boss Tobias Moers told Autocar earlier this year that the A45 will get "well over 400bhp" from its new engine, which is expected to be an extensively re-engineered version of the current car's 2.0-litre unit.

That means it will have more than 200bhp per litre, ranking the car at least 12bhp-per-litre higher than the current A45 and beating the current specific output champion, the 197bhp-per-litre Senna. The model, dubbed by AMG insiders as 'The Predator' as a nod to its extreme performance, is expected to serve a rival to Audi Sport's RS3 in the pairing's ongoing super-hatch fight, while also ensuring the A45 offers stronger straight-line performance than the forthcoming BMW M2 CSL. Despite rumours to the contrary, the model will be pure petrol and will not require a hybrid set-up to produce its headline-grabbing numbers. "It's going to be the next step in every perspective, including driving dynamics," said Moers. The A45's big power advantage will be illustrated with only small aesthetic differences. It will have a quad oval-exit exhaust system, whereas the A35 will get a dual-exit system. Also featured on the A45 is AMG' Panamericana front grille, giving the 2019 car a design nod to the recently revealed GT 4-door Coupé. The A45 will have its own unique chassis developments with optional adjustable damping offering an extreme mode for high-speed circuit running. The current A45 is renowned for its stiff adjustable set-up, but the recently sighted test cars for the next-gen model look to be sitting lower, suggesting AMG could be targeting even more body composure for track-day driving in its future model. The new A-Class is 10mm longer than today’s car and adopts a new floorpan and body structure that are claimed to provide significant increases in rigidity. This provides it with improved refinement. The new A45 will also get a significantly wider front track and receive its own unique wheel carriers in a bid to reduce unsprung mass. It will roll on standard 18in wheels, but 19in rims will be an option. The basis for the changes to the M133 engine unit comes from Mercedes’ new M260 four-cylinder engine. This is derived from the older M270 motor used by today’s A-Class but has a new crankcase and cylinder head. Initially, the reworked M133 will feature a traditional exhaust gas-driven twin-scroll turbocharger. However, AMG is also developing a more advanced variant of its new engine that uses a 48V electrical system and runs both an electric-driven turbocharger and electric motor in a hybrid set-up that promises an even greater ramp-up in performance. AMG is also looking to endow its new hatchback model with an extra 20lb ft — a move that, insiders have told Autocar, will provide it with at least 369lb ft and allow its 0-62mph sprint to crack the 4.0sec mark.
