2017 Cadillac ATSEnlarge Photo
It's inevitable the car widely considered the benchmark for luxury performance would garner its share of scorn, worship and admiration. The BMW 3-Series has certainly garnered equal parts of each and every luxury brand has the 3er in its sights.
Most competitors' shots just glance off the 3-Series' tautly drawn sides, but the Cadillac ATS is one entry that's pierced almost all of the protective armor on BMW's iconic sport sedan. Yes, the 3-Series still has the whirling-propeller badge on the hood for prestige, but whether it stands as the best compact luxury sports sedan is in question.
First, a disclaimer: We've already put the 2017 Cadillac ATS through our updated scoring system and it earned a 7.0 out of 10 overall. We haven't crunched the numbers for the 3-Series in our new system, but we're eager to see the results. Stay tuned to this space as we update those numbers. (Read more about how we rate cars.)
First, the basics. The 3-Series sedan was new for the 2012 model year, and it's been mostly carried forward since then. They're handsome vehicles, though not so different from the last generation, all the traditional BMW design bits and pieces in full flourish. Sculpted on its sides, it's a bit sallow at the front and rear, and tall of glass. The cockpit's less impressive, somehow, with a faint Toyota flavor in the sweeping curve that separates the driver from the passenger. It's dark, filled with small buttons and iDrive in some cases, and gets an afterthought of a wide LCD screen stuck to its dash on nav-equipped models, in one of the least attractive integration attempts we've seen on any luxury brand in recent memory.
The ATS? It was new for 2013. Its style is watered-down Art & Science angles, but it's still convincing in its extroverted attitude, from its exaggerated headlamps to the V-crested rear lamps. The cabin's an understated win, with great organization and a high degree of finish that really centers on versions equipped with the iPad-like CUE system. Most ATS cabins are awash in the serene blue glow that CUE casts, while drivers run audio, navigation, climate, and phone with its touchscreen, steering-wheel, or voice controls.
That unified theory of functionality has its fans, and its detractors. BMW's tried its hand at it with iDrive, and though it has Pandora streaming and such, the roller-controller school of thought looks hopelessly out of date next to CUE's swiftly changing screens, haptic feedback, and proximity-sensing surfaces. Both have their bugs, and their quirks--but a CUE-equipped ATS can come in thousands less than some 3-Series sedans without a rearview camera. Both sedans offer packages of advanced safety gear like blind-spot monitors and lane-departure warning systems; but only the ATS has seat-mounted buzzers that vibrate you when you've crossed the double-yellow line.
In terms of interior space and usability, it's the BMW's turn to shine. It's bigger inside, about the same size outside. Its rear seat is habitable, its trunk more usable; the ATS suffers from a severe lack of rear-seat leg room and cargo space, by comparison.
It's a total dogfight on all these fronts, but on the battlefield where the BMW 3-Series and Cadillac ATS will be waging war from now on, is on the performance front. The base ATS is no longer a concession to price, its 272-hp turbo-4 sits atop the base 3-Series; the 335-hp ATS V-6 and 320-hp BMW 340i turbo-6 now seem like luxuries in the class.
