Cadillac 1.9 Turbo Diesel tests at 55.6 mpg

Finally, we have some fresh content for AutoblogGreen's Cadillac category. A quick run down the list shows that some brands are just greener than others (we still haven't found anything all that green from Rolls Royce or Jaguar, for instance). The Caddy news is that two Cadillac BLS 1.9 Turbo Diesels took part in the 360-mile 2006 AA / ALD Automotive MPG Marathon this past week and reached an impressive overall fuel economy of 55.6 mpg and 52.1 mpg, respectively (measured in Imperial gallons of course). These numbers were good enough for 2nd and 3rd place based on fuel consumption and actual performance over the official mpg figure. The new 1.9 liter BLS' official mpg rating is 46.3 and it is the first Cadillac available with a turbo diesel engine. Prices start at £20,728.
