Lexus has revealed details of its latest hybrid model - the CT200h, which it says will deliver CO2 emissions of just 96g/km and return 68.9mpg.
The new hatchback features a full hybrid petrol powertrain, which means it can outperform all its competitors in terms of emissions and fuel economy.
Preliminary fuel consumption figures are quoted at 68.9mpg in combined cycle.
This means the car should offer lower fuel bills, a Band A classification for Vehicle Excise Duty giving a zero road tax charge and a company car tax benefit-in-kind bill of 10%.
Lexus stresses that this environmental performance is not achieved at the expense of performance.
The CT 200h is built on a new platform which benefits from a series of exclusively developed body, chassis and powertrain control systems.
Drivers are given the choice of Dynamic and Relaxing driving moods, via four selectable modes for the full hybrid system: Normal, Eco and EV (electric vehicle), plus a Sport setting that adjusts certain performance parameters for a more engaging drive.
Lexus designers have given the car the a low centre of gravity with a high-rigidity bodyshell, a lateral performance damper system and new double wishbone rear suspension, designed to deliver "high-speed stability, smooth and precise handling, rewarding agility and the ride comfort expected of any Lexus", says the manufacturer.
The CT 200h will debut at the Paris motor show at the end of September and will be commercially available in the UK from October, with first deliveries to customers in the New Year.
