The normal 2013 RC has to be content with having a maximum of 3,5 litres of cubic capacity and six cylinders. The letter 'F' (Fuji Speedway) on the end points out the high performance version. 1,5 litres more sounds pretty good. If however, one goes out from a normally aspired engine, the power output is put into a different light when compared with the turbo of the competition.

According to the manufacturer, the engine has undergone a number of changes. Among them, a modified controlling through the cams, which among other things, makes a backflow of the sucked-in air in the inlet port (Atkinson principle) possible. In this case, and for the first time, a manufacturer also places a limit on the enrichment at full power. This amounts to 220 km/h. Below this limit the engine runs stoichiometrically.

Toyota against the trend, which has in the meantime, even been taken up by Ferrari. It is surprising, that despite this, 530 Nm of torque is still achieved, even if at higher RPM than is common in turbo charged engines. A larger exhaust gas guiding as well as a 4 in 2 (actually an 8 in 2) system does help the performance yield. In addition, there is also the Active Sound Control.

To put the torque effectively onto the road, the built-in Torque Vectoring System has the possibility of including the rear wheels, virtually independent from one another, in the drive train. The appropriate multiple disc clutches each have an electric motor which engages mechanically and variably.

A BMW M4 appears less spectacular inside and outside, indeed, in the lower RPM range it's performance is better, in the upper range though, it's not quite as good. The price-tag is similar but the amount of CO₂ given out, is much lower. The Lexus however, does have two cylinders more, the weight of which must be calculated against the bi-turbo.

The Lexus is all together heavier, which is compensated for by the ten kilograms lighter carbon bonnet and roof. Apart from this, there are two variations, each for approx. € 4,000 extra. For the weight of the Lexus, one could have the BMW convertible or the all-wheel drive of the Audi (RS 5). The latter however revs even higher. 12/14
