The Infiniti QX70 is offered in both rear-wheel and all-wheel drive. The QX70 comes with a 325-horsepower, 3.7L V6 hooked up to a 7-speed automatic transmission that includes adaptive shift control.
Although the QX70 looks like an SUV, it drives more like a sport sedan. A double-wishbone front and multi-link rear suspension help keep the QX70 very composed and controllable in tight, fast corners and the QX70's all-wheel-drive system helps put the power to the pavement without interruption. The available solid magnesium paddle-shifters enhance the serious sport-sedan driving feel and give the driver better control over shifts, while the all-wheel drive system smartly can send up to 100 percent of power to the rear if needed. An optional Continuous Damping Control (CDC) system utilizes electronically controlled dampers to give the driver a choice between Auto and Sport modes. In addition, the available Rear Active Steer system can turn the rear wheels up to one degree in either direction to aid maneuverability at low speeds or stability and response at high speeds.
There are plenty of safety-tech features offered in the QX70 as well. Intelligent Brake Assist (IBA) and Forward Collision Warning (FCW) are systems that work with the Intelligent Cruise Control (ICC) system and its laser sensors to anticipate an imminent collision. If the driver doesn't respond, the system will automatically use the brakes to help reduce the severity of an impact. Lane Departure Prevention and Lane Departure Warning also help the driver keep within the marked lane, or help spot adjacent vehicles, and they might provide an early indication about waning driver alertness. Adaptive Front Lighting provides yet another measure to help on dark curvy roads.
All QX70 models are feature-laden like well-equipped luxury vehicles -- the difference is really in the advanced tech features that are optional. A Premium Package groups many comfort and convenience items, such as climate-controlled front seats, the navigation system, a touch-screen display, sonar parking sensors and an Around View camera system. Also, a Limited Package adds a number of appearance and convenience goodies to the Vehicle. A Sport Technology Package adds sport seats, magnesium paddle-shifters, Rear Active Steer and the Continuous Damping Control system.
The standard sound system on the QX70 is really a premium one, and includes eleven speakers. The Bose Premium Audio system includes XM satellite radio, iPod and USB connectivity, and steering-wheel controls. Optional on QX70, is a hard-drive-based navigation system that adds Bluetooth Audio streaming and voice recognition for navigation and audio, plus XM NavTraffic and NavWeather for real-time traffic and weather considerations and Zagat restaurant ratings.
The 2014 QX70's engine room offers no surprises. The midsize crossover is powered by Nissan/Infiniti's 3.7-liter VQ-series V-6 engine; the same mill that makes an appearance in nearly every vehicle in the automaker's lineup smaller than the.
The power plant makes 325 horsepower in this incarnation, sending its 267 pound-feet of torque through a seven-speed automatic transmission on the way to the automaker's Intelligent All-Wheel Drive system. This rear-biased AWD system defaults to 100 percent rear-wheel drive, but can direct up to 50 percent of available torque on demand to the front wheels when slip is detected on one of the rear wheels. Of course, the QX70 is also available standard with plain-vanilla rear-wheel drive, as well.
That the QX70's all-wheel-drive system doesn't feature any special off-road programming or settings and that its torque split is so rear-biased are both indicators that Infiniti wants you to keep this one on the tarmac. There is, however, a switch to activate a "Snow" driving mode on the center console, but this is a throttle control system for carefully creeping through slippery conditions without wheelspin, not a specific traction program.
The Good Infiniti's dashboard tech hasn't changed much for the 2014 Infiniti QX70 3.7 AWD, but it's still impressive, with a wide range of active and passive driver aid systems.
The Bad Blind-spot monitoring seems to have disappeared from the options list. The automatic gearbox sucks all of the fun out of the V-6 engine's power delivery.
The Bottom Line The 2014 Infiniti QX70 3.7 AWD gets a new name, but it's the same FX that it's always been. Fortunately, that's a good thing.
This luxury sedan has been around for ages, but that doesn't mean you should automatically avoid it.
The Infiniti Q50 is one of those cars that defies the clock. In automotive terms, it's positively ancient, yet it still looks fresh and feels welcoming.
The new QX60 is only a little more expensive than the old one to start with, and it's a much nicer crossover.
The redesigned three-row crossover has slick looks and a new infotainment setup.
We don't get much of a look, but what we do see looks decent.
The vehicle may cut power after rapid acceleration and unintentionally stall.
The newly updated system uses navigation data to make the driving experience smoother.
Unfortunately, this crossover-coupe isn't much more than a pretty face.
