Lexus-LF-NX-Concept-010

This is the Lexus LF-NX Turbo concept, one of the stars at the Lexus stand at Tokyo 2013. While the LF-NX from Frankfurt 2013 had a hybrid powertrain, the Turbo in this concept’s name explains it all – it is supposed to have a turbocharged 2.0 litre motor under its hood.

Exterior-wise, the only thing that separates the LF-NX Turbo from the LF-NX hybrid are a more aggressive alloy wheel design. Although both concepts have 20-inch wheels, Lexus has put slightly lower profile tyres on the LF-NX Turbo – 255/45 ZR20 compared to 255/50 R20. Dimensions-wise, the LF-NX is a size smaller than its big brother, the RX.

Lexus hasn’t revealed output figures for the 2.0 turbo four-cylinder under the hood yet, but we’re hoping this engine gets its usage expanded to the rest of the Lexus range, because while the 3.5 V6 has its large displacement to create lots of grunt, there could definitely be improvement to the normally-aspirated 2.5 litre V6 in the IS 250 and GS 250 as their competitors have a lot more torque.

Lexus says the new turbo engine will get fan spray D-4S fuel-injection, a cylinder-head integrated exhaust manifold, and a twin-scroll turbocharger with an active wastegate valve.
