The new Lexus RC F Track Edition is the fastest Lexus since the $1 million LFA supercar.
The back room boys have managed to shave 65kg off the weight of the car which now tips the scale at 1715kg.
As a result the Track edition now dispatches the dash from 0-100km/h in just 4.3 seconds.
The high-revving, acclaimed naturally aspirated 5.0-litre V8 produces 351kW of power at 7100rpm and 530Nm of torque between 4800rpm and 5600rpm.
The 8-speed automatic transmission debuts new AI-SHIFT control with greater intuition and, in Sport S+ mode, more aggressive downshifting than previously.
For the first time since the LFA supercar, Lexus will offer standard launch control across the RC F range to enable faster and more controlled standing-start take-off.
Courtesy of a 7.0 per cent-lighter machined intake manifold and intelligently designed new intake piping, the engine meets Euro 6 emissions standards while also providing more linear throttle response as a key improvement to driveability.
A new, more solid rear engine mount has also been developed to greatly enhance handling stability particularly at the cornering limit.
The weight savings have been achieved with the fitting of 19-inch motorsport-inspired lightweight BBS alloys and high-performance Brembo carbon-ceramic disc brakes (380mm diameter front matched by 35mm-larger 380mm units rear).
A titanium exhaust further reduces weight by 6kg, at the same time increasing the dramatic sound of the hard charging V8.
Carbonfibre reinforced plastic (CFRP) bonnet, roof, rear diffuser, lower rocker panel, front spoiler, rear wing and rear-seat brace deliver the rest of the savings.
Lexus chief executive Scott Thompson said the RC F and RC F Track Edition would make a formidable pair in the performance-obsessed Australian market.
