New details of the upcoming Lexus RC coupe have surfaced online, outlining the mechanical packages of the 'regular' model and the top-shelf RC F hero.
And, if this latest report by US website Motor Trend proves accurate, there are few surprises to be found with the new IS sedan's two-door companion.
Expected beneath the bonnets of the sub-F models are the familiar Lexus 2.5 litre four-cylinder petrol-electric hybrid and 3.5 litre petrol V6 powertrains, the latter matched to a Torsen limited-slip differential.
Power figures for the RC applications of those two engines have not been revealed, but in IS 300h and IS 350 form, they offer compelling 164kW/300Nm and 233kW/378Nm outputs.
The report adds that a new turbocharged 2.0 litre petrol engine will also feature in the range - likely at the entry end - although details of this mill have not been confirmed.
The debut of the RC range will also see the continuation of the standalone F badge, arriving as only the second full-cream performance model in the Lexus range. (Excluding the very super and very limited-edition LFA, of course... - Ed.)
The RC F will reportedly be powered by an enhanced version of the 5.0 litre V8 driving the current IS F, upgraded from 311kW and 505Nm to a solid 340kW and 545Nm.
Speaking with TMR in July, IS engineering boss Junichi Furuyama noted that extracting more power from the 5.0 litre V8 would be difficult without breaching Euro VI emissions requirements - but it seems Lexus has found a way.
According to Motor Trend, Lexus has upgraded the 5.0 V8 to include cylinder deactivation - 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.
As with the IS F, power in the RC F will be sent to the rear wheels through a paddle-shifted eight-speed Sports Direct Shift transmission.
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.
A host of LFA supercar technologies will '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, 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.
At this stage, the RC F is expected to debut at January's Detroit Auto Show - but a Tokyo Motor Show debut next month could still be in store for the regular RC models.
