5 reasons to buy the 2015 Infiniti Q40

1. Baseline luxury 

In our world of choices, it might feel constricting to find a luxury sedan that arrives without a range of trims to choose from. But there's joy to be found in an easy choice. The 2015 Infiniti Q40, which is essentially a rebrand of Infiniti's discontinued G37 series, comes in a single trim, jam-packed with all the features you might not know you need. That means there's no need to stress whether you should or shouldn't upgrade to a higher-end trim. On the Q40, almost all the perks are included standard. The only real choices you need to make are color (Liquid Platinum, Graphite Shadow, Black Obsidian, and Moonlight White), and wheel system (2WD or 4WD). 

2. Hardy powertrain 

At the heart of the Q40 is Infiniti's 3.7L 328-horsepower V6 engine. Paired with a seven-speed automatic transmission, the Q40 offers sport-level power that makes for a thrilling ride. To manage all that punch (consider 269 lb-ft of torque), Infiniti has outfitted the Q40 with a suite of invisible tech, including its state-of-the-art rev matching, quick-shift Drive Sport mode, and adaptive shift control, which makes for great handling. 

3. Intuitive entertainment 

Infiniti's immersive technology takes the new and shapes it with the practical. On the Q40's infotainment system, you'll enjoy a Bose® premium audio system, which includes a three-way front door speaker array that mixes 10-inch subwoofers and a parcel shelf-mounted subwoofer for an audiophile-level experience. Also included as standard is Bluetooth® connectivity and USB input. It's all controlled through a seven-inch color monitor display and a bevy of physical buttons and multipurpose knobs. 

4. Cozy interior 

The 2015 Infiniti Q40 doesn't sacrifice space for luxury. In the trunk, you'll find 13.5 cu-ft of storage, and across three backseats 34.7 inches of legroom. Passengers will also enjoy Infiniti's dual-zone automatic temperature control system with rear A/C vents, as well as center consoles in the front and rear that double as armrests and cupholders. This makes it a welcoming space for your daily commute. 

5. Smooth steering 

Driving is the reason you're here, and the 2015 Infiniti Q40 offers a luxury handling experience. There's four-wheel independent suspension shaped around lightweight aluminum components and sophisticated front and rear stabilizer bars, which allows you to attack sharp turns without that keeling sensation you'll find on standard sedans. Whether you're snaking backcountry roads or a sharp city grid, the Infiniti Q40's grounded center keeps its passengers comfortable.
