Acura TLX V6 vs Infiniti Q50: Outperformance by Design


2018 Acura TLX V6 Sedan

9 Speed Automatic with P-AWS®

2017 Infiniti Q50 Sedan

7 Speed Automatic

The 2018 Acura TLX V6 sedan offers exhilarating performance and luxury features that put it far ahead of the Infiniti Q50. TLX comes standard with Precision All-Wheel Steer™, Agile Handling Assist® to aid in cornering, and a 9-speed automatic transmission with paddle shifters something lacking on the Infiniti sedan. And even with a bigger engine than Q50, TLX still has better fuel economy ratings4, meaning you really can have it all.

The dramatic new A-SPEC ensures that TLX looks just as powerful as what’s under its hood. Performance-driven cues from the Acura NSX elevate the impact of the available A-SPEC: eye-catching features include round exposed dual exhaust outlets, new front lower intakes with round LED fog lights and dark chrome finish trim, and piano-black rear decklid spoiler.

2018 Acura TLX engine white background

The TLX, by contrast, has two very good engines and they are both naturally aspirated. The entry-level four-cylinder is surprisingly torquey. The optional V6 loves to rev and at full throttle it manages to sound like something you'd hear in a much more expensive car.
