This version will have a slightly different trim specification than the UK model, with changes such as smaller wheels lowering the weight and therefore allowing for the improved CO2 emissions.
A spokesman for Lexus said the heavier UK car's model grade and specification better suits the segment in which it will be competing.
The CT200h uses a tuned version of the Toyota Prius’s 1.8-litre petrol-electric hybrid powertrain and CVT gearbox.
Its electric motor and nickel hydride battery pack help propel the car up to 1.24 miles on electric power alone.
There are four selectable modes for the full hybrid system: Normal, Eco and EV (electric vehicle), plus a Sport setting.
In Sport mode, the MacPherson strut front and double wishbone rear suspension firm up and steering and throttle responses are sharpened to boost the CT200h’s agility and road holding.

Lexus has set itself the target of making the CT200h “a benchmark for handling in [its] segment” and promised it will be a “sporty” car to drive.
Lexus wants to make the front-drive CT200h a credible dynamic rival for the best-selling Audi A3 and BMW 1-series models in the lucrative premium hatchback segment.
The firm is expecting the car to shift around 30,000 units per year to double Lexus's business in Europe.
First deliveries will be made to UK customers in the New Year when it will be priced from around £21,000.
