Lexus has unveiled the revisions it has made to the IS models ahead of the Paris Motor Show. This comes in the form of a revised petrol engine, a new diesel engine and styling updates.

The IS 250 and 220d F-Sport models have gained an updated interior and exterior, inspired by the high performance IS F model. Changes include a deep front spoiler with faired-in fog lights, new grille design, rear spoiler with integrated stoplight, LED daytime running lights and new-design 18-inch alloy wheels. Inside you get an F-Sport steering wheel, gear lever and sports pedals with the front seats finished in leather and Alcantara. Up above, titanium-effect trim and a dark, anthracite roof liner can be found.

Under the hood you find a more fuel-efficient engine that still produces 205hp and 252Nm. This is seen in improved fuel consumption figures, which now stands at 7 L/100km compared to the previous 7.42 l/100km. CO2 figures have also dropped from 209g/km to 194g/km. Similar improvements are seen in the 2011 IS 250C coupe-cabriolet now only sipping 7.7 L/100km and a CO2 figure of 213g/km.

Replacing the previous IS220d is the new 200d, which produces 148hp from its 2.2 litre engine, also equipped with a diesel particulate filter to meet Euro 5 emissions standard. Peak torque is 340Nm available from 2000rpm, while the car reaches 100km/h in 10.2 seconds. Economy is superb as the car’s fuel consumption figure is 4.25 L/100 and has a relatively green CO2 emission figure of 134g/km.
