Wild Benz hy­per­car puts F1 pow­er­train tech to the road

THE CLAIM of “an F1 race car for the road” is one that has been trot­ted out plenty of time be­fore; the re­al­ity has in­vari­ably been a road car that in­cor­po­rates lim­ited tech­ni­cal el­e­ments that hap­pen to be shared with a pro­to­type racer.

How­ever when Mercedes-amg an­nounced it would build a roadle­gal hy­per­car with a driv­e­train lifted di­rectly from Formula 1, it was time to take no­tice. The Mercedes-amg Project One truly has an F1 heart beat­ing in its car­bon­fi­bre chest.

The driv­e­train’s cen­tre­piece is a mid-mounted 1.6-litre V6 with two elec­tric mo­tors – one

bolted di­rectly to the crankshafthaft to pro­vide ad­di­tional torque, the se­cond to elim­i­nate lag for thehe en­gine’s mas­sive tur­ To al­low for the strato­spher­icc max­i­mum en­gine speed of 11,000rpm, the four over­head d cams are gear driven and the val­ve­train uses pneu­mat­ics ratherather than con­ven­tional springs.

Power is de­liv­ered to the roadad through all four wheels: the rearsears fed by the V6 and its elec­tric mo­tors, while the fronts each have an ad­di­tional 60kw mo­tor.or. The purely elec­tri­cally driven front axle al­lows in­di­vid­ual ac­cel­er­a­tion ation and brak­ing of each front wheel,el, and this torque vec­tor­ing is ususedsed to fur­ther aid ve­hi­cle dy­nam­ics.dy­nam­ics. The elec­tric mo­tors also al­low the Project One to achieve a claimed­claimeed 25km pure elec­tric range.

Project One’s com­bined sys­tem­syst­tem out­put is quoted as in ex­cess ofo 740kw. That’s around the sam­sameme fig­ure as Lewis Hamil­ton’s racracee car, and enough, says Mercedes-mer­cedeesAMG, to hurl the Project One from­fr­from stand­still to 200km/h in less ththanhan six sec­onds. For com­par­a­tive pur­poses, the Mclaren P1 and La­fer­rari hit that mark in closer to seven. On a road long enough, AMG sug­gests a V-max be­yond 350km/h.
