Infiniti Q70 Hybrid: 360-HP Luxury Sedan With 31 MPG

The Infiniti Q70 Hybrid stands out as a compelling choice in the midsize luxury sedan segment, combining a potent V6 engine with electric assistance for impressive output and better-than-expected fuel economy. This model delivers smooth highway cruising and ample passenger space, making it suitable for long-distance travel or executive use, though it falls short in dynamic handling compared to sportier rivals.

Engine and Performance Breakdown

At the heart of the Infiniti Q70 Hybrid is a 3.5-liter V6 gasoline engine paired with a 50-kW electric motor, producing a combined 360 horsepower and 368 lb-ft of torque. This setup drives the rear wheels through a seven-speed automatic transmission, enabling brisk acceleration with a 0-60 mph time around 5.0 seconds. The hybrid system allows for silent electric-only starts at low speeds, transitioning seamlessly to the petrol engine as demand increases, though some reviewers note the power delivery isn’t as refined as in competitors like the Lexus GS 450h.

Real-world testing reveals strong straight-line performance, ideal for merging onto highways or overtaking. However, the chassis tuning prioritizes comfort, resulting in noticeable body roll during cornering and understeer when pushed hard. The speed-sensitive steering provides decent weighting but lacks the precise feedback found in BMW 5 Series models. For buyers seeking effortless power without drama, the Q70 Hybrid excels, particularly on open roads where its 29 city/34 highway MPG EPA rating shines, translating to about 31 mpg combined in mixed driving.

Fuel Economy and Efficiency Insights

One of the Q70 Hybrid’s strongest suits is its fuel efficiency for a performance-oriented luxury sedan. Official figures claim up to 45.6 mpg (UK) or 6.9 L/100km combined, with testers achieving 8.2 L/100km in varied conditions – respectable for a 360-hp powerhouse. The lithium-ion battery pack enables regenerative braking that recaptures energy effectively, extending range without frequent refueling.

Compared to non-hybrid Q70 variants, the Hybrid offers superior economy without sacrificing much power. Diesel rivals like the BMW 530d edge it out slightly at 53.3 mpg, but the Infiniti counters with smoother operation and higher outright performance. In urban settings, EV mode handles short trips quietly, though the petrol engine engages quickly, limiting pure-electric range to under a mile.

This table highlights the Q70 Hybrid’s balanced specs, offering more power than diesel alternatives while nearly matching hybrid peers in efficiency.

Interior Comfort and Practicality

Step inside the Q70 Hybrid, and you’re greeted by a plush cabin with supportive leatherette or leather seats, ample rear legroom, and high-quality materials. Standard features include dual-zone climate control, a rearview camera, navigation, and 18-inch alloys, with premium packs adding Bose audio, adaptive cruise, and a 360-degree camera. The wood-trimmed dashboard and bolstered front seats create an upscale ambiance, though the interface feels dated with too many physical buttons.

• Spacious rear seating for three adults, with good headroom and knee space.
• Comfortable ride quality absorbing bumps effectively on motorways.
• Advanced tech options like blind-spot monitoring and lane departure warnings enhance safety.
• Quiet cabin at cruise speeds, aided by sound insulation.

However, practicality takes a hit from the battery placement, reducing trunk volume to 11.3 cubic feet (from 14.9 in gas models) or about 350 liters – a notable compromise versus rivals without such intrusions. Front storage is limited, and the infotainment lacks modern touchscreen intuitiveness.

Safety Ratings and Driver Assistance

The Q70 Hybrid earns top marks for safety, with a five-star NHTSA overall rating and IIHS Top Safety Pick+ status, including ‘Good’ scores in crash tests and ‘Superior’ front crash prevention. Available tech like forward emergency braking, adaptive cruise, and around-view monitors with moving object detection provide comprehensive protection.

These features operate reliably, alerting drivers to potential collisions or lane drifts, making it a secure choice for families. Rear passengers benefit from stability control and multiple airbags.

Design and Styling Appeal

Infiniti’s signature double-arch grille and sleek lines give the Q70 a bold, aggressive stance, available in colors like Hermosa Blue and Chestnut Bronze. The 2015-2016 updates added 18-inch wheels and LED lights, enhancing its premium look. While not universally handsome to all tastes, it draws attention and conveys luxury.

Rear-wheel drive contributes to a planted feel, though all-wheel drive isn’t offered on the Hybrid. The long hood emphasizes its grand tourer character over sporty coupe vibes.

Ownership Costs and Rivals Comparison

Priced around $50,000-$83,000 depending on trim and market, the Q70 Hybrid undercuts some hybrids but trails in resale value due to Infiniti’s niche status. Maintenance is standard for luxury sedans, with hybrid components warrantied reliably. Fuel savings offset higher upfront costs over time.

Versus the Lexus GS 450h, it offers more power but rougher hybrid transitions; the BMW 530d wins on economy and handling; Porsche Panamera Hybrid outshines in refinement but at a premium price.

Pros and Cons at a Glance

• Pros: Potent acceleration, excellent fuel economy, spacious cabin, strong safety scores, comfortable ride.
• Cons: Reduced boot space, dated infotainment, comfort-biased handling, less seamless hybrid operation.

Who Should Buy the Infiniti Q70 Hybrid?

Ideal for executives prioritizing refinement, efficiency, and straight-line speed over twisty-road thrills. It’s a value-packed alternative in a segment dominated by German and Japanese giants, especially if diesel isn’t preferred.
