2014 Infiniti Q50 priced at $37,605*

Infiniti has released full pricing information for its new 2014 Q50 line, which, as you're probably aware, replaces the well-liked G-series sedan. You may be wondering why this is news, as Infiniti announced pricing for its new Q50 sedan back in March. Apparently, though, those earlier prices applied only to the special pre-sell offer announced earlier this year and are only good for cars ordered by October 31, 2013.
Starting in November, base 2014 Q50 models with the automaker's 328-horsepower 3.7-liter V6 engine will begin at $37,605 (*including a $905 destination fee), while the sportier Q50S model will begin at $44,105. Adding all-wheel drive to either model costs an additional $1,800 over the standard rear-wheel-drive models. Regardless of engine or whether it's rear- or all-wheel drive, the Q50 comes with a seven-speed automatic transmission.
Opting for the 2014 Infiniti Q50 Hybrid will get the buyer a powertrain consisting of a 3.5-liter V6, a 50kW electric motor and a lithium ion battery that offers up a total power output of 354 hp and a highway fuel mileage rating of 36 miles per gallon, all for a starting price of $44,855, which includes the Premium group. The most expensive version of the new sedan is the Q50S Hybrid with all-wheel drive. That model carries an MSRP of $49,055.

2014 Infiniti Q50's novel drive-by-wire steering system recalled

The gradual replacement of mechanical components in automobiles with electronic systems brings with it definite advantages, but also poses certain potential dangers. Just think of the inevitable problems you've encountered with the computer on which you're reading these words and you'll know what we mean. But a computer crashing isn't as problematic as your car going on the fritz when its electronic systems fail.
That's what Infiniti is being reminded of with its new drive-by-wire electronic steering system. The Japanese automaker developed and installed the Direct Adaptive Steering System in its new Q50 sedan, but a small number of those cars on the road are now being recalled due to that system.
According to the National Highway Traffic Safety Administration, on a small number of examples, the Q50's optional by-wire system may fail if the temperature in the engine compartment drops below freezing. There's a backup mechanical setup in place should the electronic system fail, but NHTSA says that the backup system may also fail to engage in time to avoid a crash.

Infiniti QX50 concept previews production model with variable compression engine

Infiniti revealed its QX50 concept ahead of its official debut at the Detroit Auto Show, and despite the concept title, it looks pretty much production-ready. The company calls the crossover "an evolution of the QX Sport Inspiration" concept, and that's certainly accurate. Side-by-side, the QX Sport, which we already figured was previewing a new QX50, and this concept look nearly identical. The primary changes are bumpers and side skirts that feature the obligatory aluminum trim to look like skid plates, and simple black plastic fender flares. The overall result is a crossover that is pleasant but not exactly exciting that bridges the gap between the small and swoopy QX30 and the large QX60. The plain wrapper hides plenty of impressive technology, though. Under the hood is Infiniti's fascinating variable-compression turbocharged engine. It's a 2.0-liter inline-four that can alter its compression ratio to anything between 8:1 and 14:1. The result is an engine that produces an estimated 268 horsepower and 288 lb-ft of torque. Infiniti says the four-cylinder should be about 27-percent more efficient than a comparable V6. In addition, while the company says this concept just shows a potential application of the engine, it's safe to say that you can expect it in the production model. With the new engine, the QX50 will also switch from to a front-drive platform, with all-wheel drive definitely an option or possibly standard; the current QX50 is based on the aging rear-drive FM platform used on other Infinitis and the Nissan 370Z. The other new tech buried in the QX50 concept's body is what Infiniti calls the "first production-ready incarnation" of its ProPilot semi-autonomous technology. The company doesn't go into great detail about what it will do except for handling stop-and-go highway traffic. We would hazard a guess that the system is functionally the same as the one introduced on the Nissan Serena minivan in Japan. It goes by the same name and can handle stop-and-go traffic, as well as maintain the car's lane position and distance behind other cars. It's another safe bet that we'll see this system in the production model. Other details about the car, such as the interior, have yet to be revealed. We're sure to see it as well as other information about the QX50's technology when it makes its full debut in Detroit. Related Video:
