The 2013 Lexus RX has been officially unveiled at the Geneva Motor Show.

Modestly revised, the crossover features a new front bumper, LED-infused headlights and a spindle grille. There's also restyled fog lights and an optional F Sport package with a unique front bumper and 19-inch alloy wheels.

Interior changes are limited, but include new ebony bird's-eye maple trim and optional saddle leather upholstery with contrast stitching on the seats, center console and armrests.

Under the hood, the RX 350 has a 3.5-liter V6 engine that develops 270 hp (201 kW / 274 PS) and 248 lb-ft (336 Nm) of torque. It is connected to a six-speed automatic transmission which enables the crossover to accelerate from 0-60 mph in 7.7 seconds and hit an electronically limited top speed of 112 mph (180 km/h).

On the other hand, the RX 450h has a 3.5-liter V6 Atkinson-cycle engine, two electric motors and a 288V Nickel Metal Hydride (Ni-MH) battery. This setup produces a combined maximum output of 295 hp (220 kW / 299 PS) which allows the model to run from 0-100 km/h in 7.8 seconds and hit a top speed of 200 km/h (124 mph).
