5 reasons to buy the 2018 Infiniti Q50

1. Zesty engine options

With three motivated engine configurations to choose from, the 2018 Infiniti G50 is built to satisfy your need for speed. The standard engine on the 2018 Q50 is a turbocharged 2.0L four-cylinder at a respectable 208 hp, though stepping up to the 3.0t trim yields an even more powerful 3.0L V6 at 300 hp. For maximum power underneath the hood, check out the Red Sport 400 trim with its turbocharged, 400-hp V6.

2. Available all-wheel drive

While rear-wheel drive is standard on the 2018 Infiniti Q50, those who prefer a little more traction behind the wheel can find optional all-wheel drive on the base 2.0t, 2.0t Luxe, 3.0t, 3.0t Luxe, and 3.0t Sport trims. Specifically, Infiniti's Intelligent all-wheel drive system automatically adapts to changing road conditions to deliver power and support where it is most needed.

3. Performance features

Is it a sport sedan or a luxury sedan? The 2018 Infiniti Q50 delivers the best of both worlds with plenty of sporty performance features. This is especially true on the eye-catching Red Sport 400 trim, which boasts features like transmission paddle shifters, adjustable suspension options and more.

4. Luxurious equipment

Despite the 2018 Q50's performance features, this sedan doesn't skimp on indulgent equipment inside and out. Even on its base 2.0t Pure trim, this sedan offers such niceties as automatic windshield wipers, automatic dual-zone climate control, simulated leather upholstery, and dual touchscreen displays (an eight-inch upper screen and seven-inch lower screen). Stepping up to the Red Sport 400 trim adds such driver-assistance features as forward collision warning, blind-spot monitoring, and automatic emergency braking.

5. A surprisingly roomy cabin and trunk

Inside the cabin, the 2018 Infiniti Q50 offers comfortable seating for up to five passengers. Even in the rear row, taller adults have plenty of room to stretch out and get comfortable with 35.1 inches of legroom. Up front, drivers will enjoy power-adjustable seats on every trim except for the base 2.0t. With rear seats intact, this sedan offers 13.2 cu-ft of dedicated trunk space, which is plenty for everyday hauling of luggage, groceries, and other small items.
