Mazda’s vehicles are again the most fuel efficient in the U.S. according to an annual report by the Environmental Protection Agency (EPA). In its Light Duty Fuel Economy Trends Report, Mazda topped the list of manufacturers for the 2013 model year – the second year running. The convention-defying company also led the preliminary list for the 2014 model year.

The average manufacturer adjusted fuel economy* (combined cycle) for all 2013 Mazdas sold in the U.S. was 28.1mpg (8.4l/100km), a 3.4 per cent improvement from 2012, with CO2 emissions of 316g/m (196g/km), down 3.7 per cent. According to the preliminary figures for 2014, Mazda improved further to 28.8mpg (8.2l/100km) and 309g/m (192g/km). In comparison, the overall averages for the U.S. market were 24.1mpg (9.8l/100km) in 2013 and 24.2mpg (9.7l/100km) for 2014. The EPA’s adjusted numbers are considered to reflect real-world mileage far more closely than the NEDC** fuel consumption and CO2 emissions figures used in Europe.

The achievement is largely attributable to the Mazda’s SKYACTIV Technology range of engines, transmissions, chassis and bodies, all developed from the ground up for uncompromising lightweight cars that deliver outstanding performance, efficiency, safety and driving fun. The results are also in line with the company’s strategy to optimise internal combustion, as Mazda finished first without the help of any hybrid models. Above all, this is a tribute to its unconventional and naturally aspirated SKYACTIV-G petrol engines***, which have bucked the prevailing trend among automakers towards downsizing and turbocharging. Mazda’s powerplants features a unique combination of outstanding linear output and superb fuel economy under everyday driving conditions.

The fuel efficiency of Mazda’s fleet should only increase as Mazda launches additional new-generation models with SKYACTIV Technology, starting with the all-new Mazda2 for the 2015 model year. The new subcompact’s fuel consumption will be some 20 per cent lower than the current model’s. Mazda also sees considerable room to continue improving engine efficiency and lightweight design – two of the focal points of the carmaker’s R&D activities.

The adjusted mileage figures are around 20 per cent lower than unadjusted laboratory values.
