Used 2018 Infiniti Q70 for sale 

The 2018 Infiniti Q70 is available in 3 trims with various engine and tech combinations catering to wide choices and requirements. The 2018 Infiniti Q70 is a luxury sedan with three available engine options each married to a 7-speed automatic gearbox. The trims not just only vary in luxury features but also each of them gets an entirely different powerhouse under the hood. This niche categorization is planted to make the 2018 Q70 fit in almost every luxury sedan price bracket, and it does outshine as a cost-effective option.

The versions are further subdivided into AWD and RWD categories, adding a small premium to their respective costs. However, the Hybrid avatar is available only in the RWD configuration

We Recommend

The 5.7L V8 variant with its stellar performance figure carries a hefty price tag too making the humble 3.6L V6 base variant in AWD configuration a more wise pick. The 3.6L Luxe trim takes the upper hand due to the better value of money proposition it holds for its customers in the American market.

The Q70 is powered by its old-school high displacement power mill - a 3.6L V6 naturally aspirated motor and mated to a 7-speed automatic transmission managing a decent power of 330 HP and 270lb-ft of torque. The above combination further provides a choice between AWD and RWD options and various add-on packages, adding luxury and performance to the available trims. The 2018 Infiniti Q70 provides ample power to complement its sheer size and its sound dynamics delivers a pleasurable driving experience. 

The sedan stands on a double-wishbone suspension setup at the front and a multi-link setup at the rear providing crisp cornering abilities while keeping its occupants comfortable even on rough pavements. The steering is adequately weighted enacts easy and light maneuvers at low speed and gives adequate feedback even at high-speed sprints.

The rivals, on the other hand, offer smaller engines with technically advanced powerhouses. Audi A6 premium with its 2.0L TFSI unit churns out 252 HP of power and 273 lb-ft of torque, BMW 530i offers 248 HP and 258 lb-ft torque with its 2.0L twin-turbo block and Mercedes Benz E300 have 2.0L turbocharged engine capable of producing 241 Hp of power and 273 lb-ft of torque. 

The Infiniti Q70 with its punchy performance rushes to 0-60 in just 6 seconds. The BMW 530i reflects similar clock time as the latter. Mercedes E300 is slightly slower at 6.2 seconds and Audi A6 premium is the most sedate at 6.7 seconds for 0-60 MPH. Clearly, the 2018 Q70 provides stellar performance figures and is way beyond its competitor concluding that there is no replacement for displacement.

The Infiniti Q70 is a great performer with agile handling characteristics, but it turns out to be the thirstiest of the bunch, sipping a gallon of fuel for just 18 miles in city driving and travels 25 miles on the highway. The V6 engine while putting out the best performance also gulps down the most fuel. Infiniti also has the largest fuel tank of 20gallons, which is necessary in this case.

The fuel economy figures further look horrific when compared to the frugal Audi A6 premium and BMW 530i with similar combined fuel economy figures of 29 MPG. The benefit of smaller turbocharged engines is clearly evident in the fuel economy face off. When it comes to overall combined range, the Audi A6 has the most with a combined range of 574 miles, followed by the Mercedes with 452 miles, and then the BMW at third place with 435 miles and the Infiniti at last with a combined range of 420 miles.

The Q70 is a gem in passenger comfort providing a class-leading room in both front and rear rows. The seats are layered with premium leatherette, are power-adjustable, and ventilated with heating functionality. The Infiniti Q70 stands second in trunk capacity by having 14.9 ft3 of available volume for rejuvenating family trips and long travel escapades.

The seats are comfortable, and there’s enough space in both the first and second rows, and it also has the best front row cabin space among the competition.

The Q70 has the most generous headroom of the bunch. Also, it provides the best in class cabin space to the consumers. BMW 530i is stellar in cargo capacity offering a monstrous 18.7 cubic feet. The Audi A6 Premium and Mercedes-Benz E300 trails last with 14.1 ft3 and 13.1 ft3 trunk volume, respectively.

Here is a list of the standout features in the 2018 Infiniti Q70's cabin:

• Dual-zone automatic climate control
• Heated front seats
• 10-way power-adjustable and heated front seats
• All-doors one-touch power windows with auto-operation

Infotainment System

The standard infotainment is a six-speaker audio system with Bluetooth connectivity and USB/iPod connectivity. The setup provides decent sound output, but this standard setup is near to obsolescence. The non-availability of Apple carPlay/Android Auto is a sour affair for such a premium offering. For music and ICE enthusiasts, the Q70 provides an optional multimedia pack hosting a 16 speaker Bose surround sound system.

The standard infotainment system consists of:

• six-speaker audio system
• INFINITI 8-inch color info display
• iPod/USB port
• Bluetooth
• Radio
• 10GB INFINITI Music Box
•  Optional Bose® Premium Surround Sound system with 5.1-channel decoding,
• Optional 16 speakers and Engine Harmonic Cancellation technology 

The 2018 Infiniti Q70 carries forward its genes from the older M sedan with subtle changes over the years in various iterations. The design boasts curves right from front till the end evolving a crescent shape with big swept-back headlamps and double-arched grille with 3D waved mesh at the front instituting a distinctive admirable styling. 

The dual exhaust with chrome muffler appliqué and full LED taillights give the Q70 a sportier appearance from the rear. Overall the styling is a graceful merging of elegance and modernity, making the Q70 a visual attraction. The overall dimensions of all the competitors fall almost under the same perimeter with Q70 being the least wide at 72.6 inches and Audi A6 premium at 73.8 inches is the widest of the bunch.

The 2018 Infiniti Q70 is the heaviest sedan of the group with a curb weight of 3,876 lbs, and at the same time the longest at 194.7 inches with outrageously tight competition from BMW 530i standing long at 194.6 inches. Some of the exterior features include:

• LED auto-level headlights and Daytime Running Light with Front LED fog lamps
• Attractive 10-spoke alloy wheel design
• LED rear clamps 
• Auto-dimming driver-side and inside rearview mirrors
• Twin exhaust tailpipes with chrome finisher

Infiniti Q70 vs Audi A6 Premium

The 2018 Audi A6 Premium is the cheapest option available in the premium sedan segment but it's not up to the mark in terms of performance, braking and luxury. It does excel in fuel economy, but considering a very minute difference of a mere $600, the Q70 proves to be a better deal.

Infiniti Q70 vs Mercedes-Benz E300

Mercedes-Benz E300 is the costliest option among the rivals, yet the most underpowered one. It is stuffed with loads of luxury features and great driving dynamics coupled with a decent fuel economy figure. But with a premium of over $2,500 in comparison to the Q70, the latter offers more at a lucrative price point.

Infiniti Q70 vs BMW 530i

BMW 530i's performance figures might not look attractive on paper, but with its advanced twin-turbo setup, it has proved itself to be the king of acceleration as well as frugality. It bangs on head to head in almost every measure to Q70, and with its sheer dynamics and modern looks is a tough contender to the rivals.

The Infiniti Q70 overall impresses with its sheer performance, agile handling, premium luxurious interiors. The availability of various trims and upgrades at very competitive pricing makes it a contender worth considering. On the flip side, its low fuel economy figures and dated infotainment system might maneuver some consumers looking for a more frugal and advanced option on offer.
