Lexus CT 200h: The emissions

Teh Lexus CT 200h has emissions of just 96g/km We have to go with the flow on this because, although we have no faith in the assertion that man is responsible for climate change, for as long as Governments penalise and promote cars based on the emissions of CO2 from their tailpipe (I know, it’s barking) we have to accept that car makers will respond to that stick and carrot. Which is why we see a raft of car makers churning out ‘Eco’ cars with a 99g/km emissions figure, as sub-100g/km of CO2 emissions is the Holy Grail for maximising tax effiecencies. Of course, Lexus has gone a step further and seem intent on producing only hybrid cars as soon as possible.

The new car, depicted in official drawings that accompany the latest Porsche patent applications filed in February, eschews the two-door route taken by all of its upmarket rivals for a four-door body.
