Lexus has just launched the long awaited third generation of the highly successful 2014 versions of the IS 250 and IS 350 sedans. The model line-up includes also the F Sport variants across the range and the new IS 300h hybrid model.

The exclusive new rear-wheel drive models now have longer, wider platform with a 60/40 rear-fold split seat, innovative on-board features and a more rigid body. This is made possible thanks to the new construction techniques that the brand has used for the architecture of the car. The technologically advanced IS models are further complemented by an entirely redesigned interior and exterior, including the Lexus' trademark spindle grille.

In addition, the F Sport models have more rigid platform thus delivering improved driving dynamics. Their steering and chassis is modified via an adaptive variable suspension system teamed to the new drive mode select feature.

What also differentiates the F Sport models are the bespoke interior and exterior styling packages, in which are included the front and rear bumpers, side skirts, grille, wheels and badging.

All of the IS models will also be equipped with wide range of standard equipment, such as pop-up hood, drive mode select, Lexus Remote Touch, tyre pressure warning sensors, eight airbags, satellite navigation, reversing camera, smart entry and start, and heated and ventilated front seats.

What is more, the vehicles now have increased in length of 75 mm. This results in an enhanced rear-seat legroom and greater boot space. The Lexus Enform telematics system on the other hand will provide the driver and occupants with a range of connected services like Enform Concierge (which connects to Lexus Customer Care centre, Drive Care, Lexus Dealers and Destination Assist), Destination Download, Fuel Finder, Local Search and Weather (which offers live search of current and forecast weather conditions for any chosen location.).

IS 250, IS 350 and IS 300h hybrid model will have engines mated to unique transmission (depending on the unit), and for instance the IS 350's one will be matched with an eight-speed transmission.

Under the hood of the 2014 Lexus IS 250 one can find a 2.5-litre all-alloy V6 unit which generates 208 hp (153 kW) and 252 Nm (186 lb-ft) of torque. It is mated to a six-speed sequential transmission with throttle blipping and fast shift capabilities.

Next, the IS 350 models produce 317 hp (233 kW) and 378 Nm (279 lb-ft) thanks to their all-alloy 3.5-litre V6 powerplant matched to a new eight-speed transmission. In addition, this model also benefits from a wider spread of gears and the addition of IS F-style shift logic with quick shift and throttle blipping.

On the other hand, IS 300h's 2.5-litre four cylinder petrol-electric hybrid powerplant generates a combined power output of 223 hp (164 kW), but still manages consuming only 4.9-litres of fuel per 100km, while emitting just 113g of CO2 per kilometre.

The new hybrid powerplant is matched with an electronically controlled continuously variable transmission (E-CVT), offering six-step shift logic and paddle shift. Thanks to the dubbed 'shift-matic', the new transmission reacts more quickly to driver inputs and road conditions to offer greater response and control.

2014 Lexus IS models will be available from mid-July.
