2015 Cadillac ATS vs. 2015 Cadillac CTS Review

Comparison Review

Introduction
The 2015 Cadillac ATS and 2015 Cadillac CTS are siblings, with the smaller ATS serving as an entry-level sedan and the larger CTS doing duty as General Motors' flagship brand's mid-size entrant. Additionally, the ATS is available in a coupe version to go along with the sedan.

Performance/Fuel Economy
The 2015 Cadillac ATS offers three engines: A 2.0-liter turbocharged four-cylinder, a 2.5-liter naturally-aspirated four-cylinder, and a 3.6-liter naturally-aspirated V-6. The turbo four makes 272 horsepower, the 2.5-liter makes 202 horsepower, and the V-6 makes 321 horsepower. All-wheel-drive is available with all but the 2.5-liter engine, and rear-wheel drive is standard. Six-speed manual and six-speed automatic transmissions are available.

Interior
Both of these Cadillacs have available navigation, satellite radio, a USB port, an auxiliary jack, streaming internet radio, Bluetooth, and an infotainment system (dubbed CUE for Cadillac User Experience). Both also offer an in-car 4G LTE hotspot and wireless cell-phone charging.

Comfort/Utility
As might be expected, the larger CTS offers more interior room and trunk volume.
So the CTS gets the edge on space, but the ATS does offer the more stylish coupe body style, which will appeal to some.

Safety
In National Highway Traffic Safety Administration crash testing, both of these vehicles scored the best possible on all four tests: Five out of five stars. This applies to overall, frontal impact, side impact, and rollover crashes. That makes it a wash when it comes to safety.

Conclusion
The CTS is larger and more powerful, so it gets the nod for those two categories. However, the smaller, more fuel-efficient ATS will appeal to those who are slightly more frugal, or those who have an interest in the two-door coupe body style. These Cadillacs may be siblings, but one has a larger footprint than the other.
