About This 2015 INFINITI Q70 3.7 Sedan
At 92,878 miles, this 2015 INFINITI Q70 sits comfortably in a mileage range that buyers and used-car shoppers should feel confident about. The Q70 — INFINITI's flagship rear-wheel-drive luxury sedan — was engineered to last well past 150,000 miles with proper maintenance, which means there's still a strong chapter ahead for this car. The gray exterior gives it a refined, understated presence that holds up well over time and pairs naturally with the Q70's sophisticated body lines. Whether you're commuting through Irvine or heading up to Los Angeles for business, this sedan carries itself with the kind of quiet authority that puts it in a class above typical used luxury offerings.
2015 INFINITI Q70 Performance and Engine
V6 3.7-Liter Power and Real-World Driving
The 2015 INFINITI Q70 3.7 is powered by INFINITI's well-regarded VQ37VHR V6, displacing 3.7 liters and producing around 330 horsepower and 270 lb-ft of torque. This is the same engine family that powered the celebrated Nissan GT-R in an earlier iteration — it's a proven, responsive unit with a strong track record. Paired with a 7-speed automatic transmission with paddle-shift manual control, the Q70 3.7 delivers crisp, confident acceleration whether you're merging onto the 5 Freeway or cruising Pacific Coast Highway.
The rear-wheel-drive layout gives the Q70 a driver-focused character that front-wheel-drive luxury sedans simply can't match. Steering feel is precise, weight distribution is balanced, and the chassis communicates with the driver in a way that makes highway miles genuinely enjoyable rather than fatiguing. Southern California's dry, temperate climate is also ideal for RWD ownership — you get the performance benefits without the seasonal concerns drivers in colder regions face.
INFINITI Q70 Features and Interior
Luxury Cabin, Premium Technology
The Q70 3.7 trim level brings a well-appointed interior that competes directly with the BMW 5 Series and Mercedes-Benz E-Class of its era. Buyers can expect premium leather seating, a wood and aluminum trim package, dual-zone automatic climate control, and a BOSE premium audio system. The infotainment setup includes INFINITI's navigation system with a dual-screen display — sophisticated for its time and still very functional today.
The rear seat in the Q70 offers genuinely generous legroom for a sport sedan, making this a realistic choice for buyers who occasionally carry passengers or use the back seat professionally. Visibility is strong, the cabin is well-insulated from road noise, and the overall build quality reinforces what INFINITI was trying to achieve: a true luxury experience at a slightly more accessible price than German alternatives.
INFINITI Q70 Reliability and Ownership
What Owners and Mechanics Say About the Q70
The INFINITI Q70 — and its predecessor, the M-Series — built a loyal following among enthusiasts who value reliability as much as performance. The VQ37 V6 is one of the most respected engines in the segment, known for durability, smooth power delivery, and a relatively straightforward maintenance schedule. Common ownership costs are predictable: oil changes every 5,000–7,500 miles, brake maintenance, and periodic tire rotations are the bread and butter of Q70 upkeep.
Consumer satisfaction ratings for this generation of the Q70 are consistently strong, particularly in the categories of powertrain reliability and interior comfort. At under 93,000 miles, this example is likely past the initial depreciation curve but hasn't yet reached the higher-mileage territory where more significant repairs tend to surface. For buyers in Santa Ana and throughout Orange County, that's a smart place to buy in.
