Acura TLX Vs Infiniti Q50 Review

The new Infiniti Q50 features a turbocharged 2.0 liter 4-cylinder engine with 7-speed automatic transmission that provides a fun ride. However, for the luxury midsize sedan segment an upgrade to the V6 engine is definitely needed to compete. The Q50's last full re-design was in 2014, so the interior definitely looks dated and is not as upscale as other luxury vehicle options. The Q50 also offers many advanced safety features and standard tech, but the infotainment system is not very user friendly, especially while driving. Finally, the interior is pretty loud, especially at high RPMs, so the Q50 doesn't have the same quiet, relaxed feel as other luxury vehicles options. Overall, the Infiniti Q50 is due for an overhaul with new engine options and updated interior design. 

The Acura TLX is a roomier, more fuel-efficient, more comfortable, more upscale, and less expensive midsize luxury sedan. The TLX offers a sporty 206-horsepower 4-cyclinder engine, which can also be upgraded to a powerful V6 engine to compete with the most expensive luxury midsize sedans. The TLX transmission shifts beautifully and the Super Handling All-Wheel Drive (SH-AWD) adds to an already sharp-handling car as it shifts power to different wheels to hug corners or plow through the snow. 

The Acura TLX kicks the Infiniti Q50's bumper in almost every category like exterior design, interior design, performance, technology, and fuel-efficiency. Plus, you can get a new TLX for an incredible price with an Acura lease deal! Acura offers many special incentives for low-price leases with special mileage forgiveness and mileage rollover benefits.
