It seems Lexus has inadvertently let the cat out of the bag this week, if reports of a leaked invitation to the unveiling of its new RC F flagship coupe are to believed.
According to enthusiast site autoblog.com, an anonymous tipster has passed along their invitation to the special event. Little is revealed in the invite, except for one key detail: the RC F's engine.
There has been some debate over what would power the new high-performance coupe, but if this latest leak is authentic, we can look forward to finding a 343kW V8 engine under the bonnet.
The leaked info adds credence to a report published in August, which described a 5.0 litre V8 engine - likely an upgrade of the current IS F sedan's mill - producing upwards of 340kW.
If true, the new RC F's coupe will offer a handy power boost over the powertrain of the IS F sedan, which offers 311kW and 505Nm (torque figures for the RC F remain unknown).
By comparison, BMW's newly revealed M4 coupe is powered by a turbocharged six-cylinder engine, producing 317kW and 550Nm.
According to that earlier report, Lexus has added cylinder deactivation to the big V8 - the first Lexus or Toyota model to feature the technology - which will see four cylinders deactivated during highway cruising.
Combined with other tweaks throughout the RC F's drivetrain, it is believed the system will see the new performer satisfy the EU's strict requirements.
And, while the RC F's power boost isn't a huge leap, the new halo model's body is expected to be a good deal lighter than its four-door predecessor.
As with the IS F, power in the RC F will likely be sent to the rear wheels through a paddle-shifted eight-speed Sports Direct Shift transmission.
A host of LFA supercar technologies should 'trickle down' to the RC F, including its lauded carbon-fibre production system that will form panels for the coupe's bonnet, roof and boot lid.
As seen in TMR's spy photos and the official teaser images, the bonnet in the RC F will also feature an air intake - not to feed a turbo intercooler as once suspected, but to channel air under the body for improved downforce.
Expect the LFA development program to make contribution's elsewhere in the RC F's development, including chassis enhancements and suspension tuning.
The RC F will debut at January's Detroit Auto Show. Stay tuned to TMR for more.
