LEXUS RC F PROMISES "MORE THAN 330KW"
Lexus has revealed key specifications for its new RC F performance coupe, unveiled at this week's Detroit Auto Show after first landing online last week.
But, while the carmaker has at last delivered details on its BMW M4 fighter, it remains cagey on exact numbers for the RC F's "all-new engine".
For now, Lexus has confirmed that the engine boasts the same 5.0 litre displacement as the coupe's IS F sedan predecessor, but with a host of new technologies.
Lexus says the new engine produces "well above 330kW and more than 520Nm", putting it well beyond the 311kW/505Nm of the IS F - and the 317kW of BMW's new turbocharged six-cylinder M4 coupe.
It remains to be seen, of course, if the RC F's "more than 520Nm" eventual torque figure will match or better the M4's 550Nm.
Why the lack of specificity? Lexus says it's still in the final development stages of the production RC F, meaning that it could be some months before we know more.
The company says it is shooting for fuel figures and a 0-100km/h time that betters the IS F sedan, meaning it will need to improve on 11.4 l/100km and a 4.8 second sprint.
It may need to rely on the new engine to achieve those figures, with an expected "below 1800kg" kerb weight possibly making the RC F heavier than the 1700kg IS F sedan.
Features of the new 5.0 litre 32-valve V8 engine include new cylinder heads and parts designed for greater power at higher revolutions "than has previously been possible".
Fuel consumption will also benefit from the use of the Atkinson cycle at cruising speeds, switching to the Otto cycle for occasions demanding greater performance.
Drive is again sent to the rear wheels through an eight-speed automatic transmission, understood to be a redeveloped version of the Sports Direct Shift system used in the IS F.
A Torque Vectoring Differential is also on board, featuring Standard, Slalom and Track driving modes.
Suspension is by coil-spring independent systems at both ends, with monotube gas dampers and ball-jointed stabiliser bars.
There's also an active rear wing, raising from the rear deck at 80km/h and staying up until the vehicle's speed drops below 40km/h.
Three variations of 10-spoke 19-inch forged aluminium wheels will be offered, with two machine-polished options and, on the 'High Plus' grade, the wheels are hand polished by a craftsman.
An optional Carbon Package will also be offered, switching out the bonnet, roof and wing fixtures for carbon-fibre pieces.
With the regular RC coupe expected to hit Australia later this year, watch for the RC F to land sometime in early 2015.
Expect a price in the ballpark of $130,000.
