Yep, that link goes to the UK site. The Canada site lists only the limited one special edition in addition to the usual models. No MHD nor diesel for Canada yet.
And I don't know if the MHD motor is any different. The MHD isn't a hybrid in the sense of a Prius, it simply turns off the engine at stops and restarts it when you let off of the brake. Bigger alternator, bigger starter, and a controller to handle all of that stuff, and a neat little backlit display in the car. It should all fit in your luggage for your flight back from London.
