Recently Mini was quick to run a large advertising campaign across the country to showcase the Cooper D as Australia's most fuel efficient car.
We can imagine Toyota's marketing department wasn't awfully happy with that, knowing the new Prius was only weeks away.
In it's first full month on sale, close to a quarter of new Mini buyers chose the Cooper D. Mini, which is owned by BMW, says local orders are almost twice the expected level.
The Mini Cooper D uses 3.9L/100km and emits 104grams of CO2 per kilometre. In comparison the new Toyota Prius (which will go on sale this month) uses the same amount of fuel (petrol) but emits CO2 at the rate of 89g/km.
You do have to wonder, given the Mini is just a simple diesel engine, why the Prius will all its technology is only 13 grams of CO2 better per kilometre?
Mini says it is happy to share the title of "Australia’s most fuel efficient car" with the Prius.
“We’re delighted with the significant Australian interest in the new Mini Cooper D. The customer response has been well above our expectations and we’re seeing a new breed of Mini customer walking into showrooms well aware of the car’s credentials. Customers placing orders report they like the perky performance, typical Mini go-kart handling and outstanding fuel consumption." said Mini Australia national manager, Justin Hocevar.
Although Toyota has no need to make mention of the Cooper D sharing its title as the most fuel efficient car in Australia, Mr Hocevar said : “Mini also warmly welcomes the new Prius to the sub-four-litre club.
"The Cooper D and now the new Prius both exemplify the strides manufacturers are making to reduce fuel consumption and greenhouse gas emissions”.
The new Mini can travel over 1000km on a single tank, for example, a Mini Cooper D, with its tiny 40-litre fuel tank, could make its way from Sydney to Melbourne without stopping for more fuel.
If you had a choice, would you buy the Mini Cooper Diesel or the new Toyota Prius?
