All-new iteration of Japan’s 3 Series
promises to be sharper, sportier, cleaner and more distinctive than ever
Lexus chose the recent Detroit motor show
to unveil an all-new IS sedan range, including a hybrid version of its 3 Series
rival. Although powertrain details for SA are yet to be announced, expect two
non-hybrid petrol-engine models, badged IS250 and IS350, to feature. Powering
the IS250 is a 152kW 2.5-litre V6 petrol engine mated with a six-speed
automatic transmission. IS350 musters 233kW from its 3.5-litre V6 and adopts
the eight-speed automatic transmission from the IS-F.

IS Front design
The first hybrid Lexus IS, badged IS300h,
combines an electric motor with a 2.5-litre four-cylinder petrol engine. The
total torque output is yet to be confirmed, but there’s 162kW of combined
system power driving the rear wheels through a CVT gearbox. Lexus is aiming for
a sub-100g/km CO2 output and fuel consumption in the region of 4.3L/100km,
hoping figures like that will help close the gap on rivals like the BMW 3
Series, Mercedes C-Class and Audi A4.

As for the interior, Lexus claims
inspiration has come from the LFA supercar, but the bigger GS has clearly
influenced the design too. Lexus hopes a wider track (+10mm) will help its
quest for more agile handling, while a longer wheelbase (+70mm) should mean a
significant increase in rear cabin space for passengers. Apparently the
hybrid’s practicality won’t suffer despite the electric hardware either: the IS
300h’s battery has been located beneath the boot floor, so it doesn’t intrude
on the load space length.

The 2013 Lexus IS incorporates new laser
welding techniques aimed at increasing overall rigidity. The double wishbone
front suspension has been revised to increase roll stiffness, while a quicker
steering rack should ensure a more agile car. An even sportier F model will be
available, distinguish able by its larger spindle-shaped grille, which Lexus
says is necessary to provide the extra cooling ‘needed for sportier driving’.
