2016 Cadillac Boosts Fuel Efficiency in CTS and ATS Models with New Engine

Cadillac has replaced the 3.6-liter V6 engine in the CTS and ATS models with a new, more fuel efficient 3.6-liter V6 engine.

It might sound strange replacing the V6 engine with another V6 engine at first sight, but the company has made the move to make the sedans more fuel efficient.


The main difference in the new engine is fuel efficiency, as the new 2016 CTS and ATS models will get EPA combined rating of 24mpg, which is a 2mpg improvement of the rear-wheel model. The all-wheel drive model also got boosted, with EPA rating now at 22mpg, which is a 1mpg improvement over the existing version. It is a small, 9 percent improvement, but albeit a nice one. The new engine also offers 8% improvement in the carbon emission area.

Another big difference is power, as the new 3.6-liter V6 engine produce 335 ponies under the hood, a slight improvement over the 321 ponies of the current version. The new engine is borrowed from the 2016 CT6 luxury sedan that Cadillac introduced previously. The engine works in a different way, as it features a technology that can deactivate cylinders, resulting in a four cylinder engine work under lighter loads.

The 2016 Cadillac ATS and CTS models also got a new automatic start and stop button, as well as the improved eight-speed automatic gearbox. The start-stop button is now standard in the 2.0-liter model as well and the lower end models also received the eight speed automatic gearbox. Fans of the six speed manual will have to look for another model, as the eight-speed automatic is the only transmission option for the new CTS and ATS Cadillacs.


And while Cadillac improved the 3.6-liter V6 engines, experts believe that the 2.5-liter and 2.0-liter turbo engines will still attract more buyers due to their better fuel efficiency. And for those who want performance oriented car, the 6.20liter V8 or the supercharge CTS-V are better options.

Some minor updates to the technology aspect include the introduction of Android Auto and Apple CarPlay to the dashboard. There are also new paint colors for the interior and exterior of the vehicle. The price for the updated CTS and ATS models is still unknown, but we can expect a slight raise from the current models. For comparison, the current 3.6-liter versions of the CTS model are priced as following: $53,285 for the luxury collection plus $2,000 for an all-wheel drive model and $58,285 for the performance collection with $2,000 increase for the AWD model.
