2017 Acura TLX vs. 2017 Infiniti Q50

If you’re searching for a new luxury sport sedan that combines modern technology with strong reliability, you’ve probably got the 2017 Acura TLX and 2017 Infiniti Q50 on your shopping list.

Both boast excellent high-tech features along with impressive performance and a reputation for durability and dependability.

But which one is better? We took an in-depth look to find out.

Performance and Fuel Economy

The Infiniti Q50 comes in an endless array of models that begins with a 208-hp 2.0-liter 4-cylinder turbocharged engine. This can be upgraded to a 300-hp 3.0-liter V6 with a twin turbo in the 3.0t model, which represents the mid-level model. At the highest end, the Q50 Red Sport 400, which offers a tuned 3.0-liter twin turbo V6 that creates 400 horsepower.

The TLX offers two simple engine options: a standard 206-hp 4-cylinder engine and an optional 290-hp V6 engine. Nothing that blows you away like the Q50 on paper, but these options offer exactly what most car buyers want and need without sacrificing fuel economy.

Speaking of fuel economy, this is where the TLX completely dominates the Q50. It’s not even close for any of the models, especially when comparing the standard and mid-level V6 options.


Reviewers of the Q50 have claimed the steering can feel choppy and less precise than others in its class. The leads to the ride feeling uncomfortable, instead of the fun and engaging experience you’d expect from this level of luxury sedan

But the TLX is touted as being comfortable while still offering a sense of sportiness. One of the best highlights is just how quiet the TLX is on the road as very little external sound penetrates the cabin. It’s easy to drive and right on point with what we expect at this price. By no means is it a sports car, but the TLX provides plenty of engaging driving moments.

Same goes for the TLX interior, which is not only comfortable, but premium looking thanks to the wood accents and soft-touch materials used throughout the cabin.

In comparison, the interior of the Q50 feels sporty, but not as mature and sophisticated as the TLX. Mainly due to the aluminum trim.

Both cars use two infotainment screens in the center stack to provide a wealth of information. In the Q50, both screens are touch-sensitive, although you can also use a control knob on the center console to manipulate the top screen.

The setup in the TLX is easier to use, with the lower display being a touch-sensitive unit that provides audio and climate information, while the top screen displays navigation and other information.

Although there is slightly more space for passengers in the Q50, it isn’t enough to really sway us away from preferring the cabin in the TLX. Furthermore, the TLX features more trunk space and comes with 60/40 folding rear seats, something that’s an optional extra on the Q50.

Features and Pricing

Furthering the appeal of the TLX is the accessibility to high-tech features at a lower cost. Equipped with a blind-spot warning system, lane departure warning, lane keep assistance, adaptive cruise control, parking sensors, front collision warning, you get access to a ton of great features without adding too much extra cost to your vehicle.

The TLX represents the true bang-for-your-buck winner in the world of premium sedans. In order to match the TLX feature-for-feature, you will need to spend $51,885 on a Q50. Then again it can be less expensive than that if you’re willing to forego some of the high-end accoutrements, as all-wheel drive Q50 models start at $39,855.


Raw performance numbers are in favor of the Q50, but fuel economy, comfort, and pricing are on the side of TLX.

Infiniti is taking the direction of trying to create sports car that look like sedans. Acura is trying to create the most balanced luxury cars ever created by doing everything right and not sacrificing quality in any area that might be important to its customers.
