2015 INFINITI Q70: A Detailed Overview
The 2015 INFINITI Q70, previously known as the M sedan, is a luxury midsize sedan that offers a compelling blend of performance, technology, and refinement. Designed to compete with established players in the segment, the Q70 distinguishes itself with its powerful engines, engaging driving dynamics, and a host of advanced features.
Highlights
-
Potent Powertrains: The 2015 Q70 offers two distinct engine options:
- 3.7L V6: This naturally aspirated V6 engine produces a robust 330 horsepower and 270 lb-ft of torque. It provides ample power for everyday driving and spirited acceleration.
- 5.6L V8: For those seeking truly exhilarating performance, the available 5.6L V8 engine delivers an impressive 420 horsepower and 417 lb-ft of torque. This engine offers a more potent and engaging driving experience, with effortless acceleration. Both engines are paired with a responsive 7-speed automatic transmission with manual shift mode and downshift rev-matching, ensuring smooth and engaging gear changes. All-wheel drive (AWD) is available on select trims for enhanced traction in various weather conditions.
-
Advanced Safety Features: INFINITI prioritizes safety, and the 2015 Q70 comes equipped with a suite of advanced driver-assistance systems designed to prevent accidents and protect occupants:
- Predictive Forward Collision Warning (PFCW): This innovative system goes beyond simply detecting the car directly in front. It can detect two cars ahead, providing an earlier warning of potential collision risks.
- Forward Emergency Braking (FEB): If the PFCW detects a high risk of a frontal collision and the driver doesn't respond, FEB can automatically apply the brakes to help mitigate or avoid the impact.
- Blind Spot Warning (BSW) and Blind Spot Intervention (BSI): BSW alerts the driver when another vehicle is detected in the vehicle's blind spot. BSI takes it a step further by providing a gentle brake application to help guide the vehicle back into its lane if the driver attempts to change lanes while a vehicle is in the blind spot.
- Around View Monitor (AVM) with Moving Object Detection (MOD): Utilizing multiple cameras, AVM provides a virtual 360-degree bird's-eye view of the vehicle's surroundings, making parking and maneuvering in tight spaces significantly easier. MOD adds another layer of safety by detecting moving objects within the camera's view.
- Intelligent Cruise Control (ICC) with Distance Control Assist (DCA): ICC automatically maintains a set speed and distance from the vehicle ahead, reducing driver fatigue on long journeys. DCA assists in maintaining the set distance by automatically adjusting throttle and braking.
-
Trim Summary: The 2015 Q70 was offered in several well-equipped trims, each building upon the previous one:
- Q70 3.7: The entry-level trim, still offering a luxurious experience with a potent V6 engine and a good array of standard features.
- Q70 3.7 AWD: Adds all-wheel drive capability for enhanced traction.
- Q70 5.6: Features the powerful 5.6L V8 engine, providing a significant performance upgrade.
- Q70 5.6 AWD: Combines the V8 power with all-wheel drive.
- Q70 Hybrid: For those prioritizing fuel efficiency without compromising on performance, this model offered a sophisticated hybrid powertrain.
-
Other Notable Aspects:
- Premium Interior: The Q70's cabin is a testament to INFINITI's commitment to luxury, featuring high-quality materials, comfortable and supportive seating, and a driver-focused cockpit.
- Engaging Handling: Beyond its straight-line acceleration, the Q70 offers a surprisingly engaging driving experience with responsive steering and a well-tuned suspension that balances comfort and sportiness.
- Infiniti InTouch™: This infotainment system provided access to navigation, audio, climate control, and connectivity features, managed through a central display and often complemented by voice recognition.
What to Expect
Owning a 2015 INFINITI Q70 is generally characterized by a premium and refined ownership experience. You can expect a comfortable and quiet ride, especially on the highway. The powerful engines offer effortless cruising and confident overtaking. The interior is a pleasant place to spend time, with well-appointed materials and supportive seats contributing to long-distance comfort.
Maintenance: As a luxury vehicle, the Q70 will typically require scheduled maintenance at INFINITI dealerships or reputable independent mechanics specializing in luxury imports. Routine services like oil changes, filter replacements, brake checks, and tire rotations are standard. Due to its more complex systems (especially if equipped with the V8 or hybrid powertrain), some specialized maintenance may be required over time. It's advisable to follow the manufacturer's recommended maintenance schedule diligently to ensure longevity and optimal performance.
Insurance: Insurance costs for the 2015 INFINITI Q70 will likely be higher than for a non-luxury or mainstream sedan. This is due to its luxury classification, higher performance capabilities, and the cost of parts and labor for repairs. Factors like your driving record, age, location, and chosen coverage levels will significantly influence your premium. Comprehensive and collision coverage are highly recommended for a vehicle of this caliber.
Potential Considerations
While the 2015 INFINITI Q70 offers many strengths, potential buyers should be aware of a few considerations:
- Infotainment System Usability: Some reviewers and owners have noted that the INFINITI InTouch™ infotainment system, while feature-rich, can occasionally feel less intuitive or modern compared to some competitors of the same era. The user interface might require a slight learning curve.
- Fuel Economy: While the 3.7L V6 offers respectable performance, its fuel economy is on the lower end for the segment, especially when compared to some turbocharged V6 or hybrid rivals. The 5.6L V8 will naturally be less fuel-efficient. The Hybrid model addresses this, but its availability might be more limited.
- Rear Seat Space: While not cramped, the rear seat legroom and headroom are adequate but may not be as generous as some larger sedans or even some competitors in the same class, particularly for taller passengers.
- Ride Comfort vs. Sportiness: The Q70 aims for a balance between a comfortable ride and sporty handling. While it achieves this well for many, some drivers seeking an exceptionally plush or an extremely aggressive sport-tuned ride might find it a compromise.
Overall Summary
The 2015 INFINITI Q70 is a compelling luxury midsize sedan that offers a potent combination of powerful engines, advanced safety technologies, and a refined interior. It provides a luxurious and engaging driving experience, making it a strong contender for those seeking a stylish and capable vehicle. While its infotainment system might not be the most cutting-edge by today's standards and fuel economy isn't its strongest suit, its overall performance, comfort, and the availability of advanced safety features make it a noteworthy option in the pre-owned luxury sedan market.
