Sport mode keeps the engine going a lot longer, plus it'll be more keen to bring the engine back in. So - in normal when slowing down to traffic lights, the CT would turn the engine off at the 45mph point. In sport mode, it'll keep the engine on until you're stopped. Other qu (apologies for the formatting - I blame work firewall!) - Electric at high output = should be ! But it'll go for the engine + motor together anyway.
