Another set of fuel-economy figures for the 2013 Cadillac ATS was released by the Environmental Protection Agency. What the EPA did this time was to test the new ATS sports sedan with its 3.6-liter V-6 engine and six-speed automatic transmission. Models that have rear-wheel drive offers a fuel economy rating of 19/28 mpg (city/highway).
Meanwhile, an ATS with all-wheel drive returns 18/26 mpg. The 2013 Cadillac ATS is available with the optional V-6 as its most powerful engine, delivering 321 hp and 275 lb-ft of torque. It was reported previously that the car’s base engine -- a 2.5-liter inline-four with an output of 202 hp, has a fuel economy of 22/33 mpg. This engine is available only with an automatic transmission and rear-wheel drive.
The Cadillac’s new 2.0-liter turbo-four engine that delivers 272 hp and 260 lb-ft. Cadillac anticipates that the turbo engine will make up around half of all 2013 ATS sales. Buyers can choose from either rear- or all-wheel drive. It’s also the only way to use an ATS with a six-speed manual transmission. It’s likely that this turbo engine will have a fuel economy that would fall in between the ratings for the 2.5-liter and 3.6-liter engines.
In comparison, the 2012 Mercedes-Benz C350 sedan has a 302-hp 3.5-liter V-6 that offers 20/29 mpg with rear-wheel drive. Meanwhile, the 2012 Infiniti G37 sedan has a 328-hp 3.7-liter V-6 that returns 19/27 mpg with an automatic transmission and rear-wheel drive, or 18/25 mpg with all-wheel drive.
Furthermore, the 2012 Lexus IS350 sedan is powered by a 306-hp 3.5-liter V-6 engine that could return 19/27 mpg with rear-wheel drive, and 18/26 mpg with all-wheel drive. The 2013 Cadillac ATS has a starting price of $33,990 (including destination charges). However, buyers who ask for the 3.6-liter V-6 engine will need to pay a starting price of $42,090.
Taking into consideration fundamental measures for and guiding principles all throughout its development, the Cadillac ATS became one of the segment’s lightest cars in a nuanced approach that ensures a more refined driving experience.
David Masch, Chief Engineer of ATS, said that Cadillac ATS’ low weight features give it a controllable and more nimble feel while optimizing at the same time the efficiency and performance of the power trains. However, careful planning was made in managing the weight while at the same time maintaining Cadillac’s traditional levels of refinement.
The idea of optimizing the mass of Cadillac ATS’ mass results from the four-pronged philosophy which included strict observance to the original architectural goals, specifically measured load management, benchmarking components used to determine if lighter solutions are available and a total culture which weighed the mass in every component of the car alongside all the aspect of its new developments.
To supply Cadillac ATS’ low-weight measures, it is equipped with corresponding engine mount brackets made of magnesium, aluminum hood and lightweight door trim panel made of natural fiber.
Such features also add up to the systematic method of weighing up every gram that goes into the car. Some weight may not only be beneficial but also essential to the overall driving experience such as the newly discovered cast iron differential wherein the engineers found out that they could develop fuel economy using such deferential rather than the usual lighter aluminum version.
