INFINITI Q50 Interior

First up to challenge the INFINITI Q50 is the Acura TLX. For fairness, we’ll compare similarly equipped versions of both luxury sedans. In terms of performance, the Q50 LUXE AWD has greater horsepower and torque than the TLX SH-AWD. Two standard features found on the exterior of the Q50 which help enhance visibility during harsh weather conditions are LED fog lights along with rain-sensing windshield wipers. You’ll be forced to shell out additional cash in order to get both features on the TLX.

For even greater peace of mind, the basic warranty coverage found on the INFINITI Q50 exceeds that provided by Acura by a full 10,000 miles. Similarly, you’ll also enjoy the same 4 years of roadside assistance coverage as you’ll get at Acura without any restrictions on mileage during that time frame. In terms of comfort and overall space, the Q50 offers more headroom and legroom across both the front and rear rows of seating. You will also appreciate the greater fuel tank capacity and shorter turning radius on your daily commute. No matter which way you look at it, the INFINITI Q50 outperforms the Acura TLX.

INFINITI Q50 Technology

The next challenger to face off against the INFINITI Q50 is the Lexus IS. Comparing the Q50 LUXE AWD against the IS 300 AWD, INFINITI continues to have the edge in terms of performance thanks to greater horsepower and torque from its twin-turbocharged engine. Despite the increased power and performance, the INFINITI Q50 still carries a slight edge in fuel economy – such is the magic of turbocharging. A larger trunk capacity helps you fit that extra suitcase for your next weekend getaway.

An extra 10,000 miles of basic warranty coverage helps highlight the commitment to quality you’ll appreciate when you choose INFINITI. Sportier styling, as well as a 360-degree surround-view camera, are other reasons to drive an INFINITI Q50 instead of a Lexus IS. While the Lexus may be slightly cheaper than the INFINITI at first glance, you’ll find that the INFINITI is the far better choice once you add those missing options to the Lexus – if they’re even available at all.
