Infiniti teases G-replacing Q50 ahead of Detroit debut

Preparing for the introduction of its new naming system and redesigned entry-level sedan, Infiniti has released a brief teaser video for the 2014 Q50. As a refresher, the Q50 is the replacement for the G37 sedan, and while we've seen spy shots of this car before, this video is our first detailed look at the production car.
All we get to see in the video is a shot of the headlight, but we get to see key elements like the stylish daytime running lights, crescent-shaped parking lights and adaptive low beams. The overall shape of the headlight is very close to what we saw earlier this year on the LE Concept. We have to wait until the Detroit Auto Show kicks off in a couple weeks to see the Q50's full design (although we're sure there will be some leaks before that point), but until then, check out the short video posted after the jump.

New details emerge on Inifiniti QX50’s unique new variable-compression engine

Infiniti will release the world's first production variable-compression engine when it releases the 2019 QX50 midsize SUV sometime next year. Now we have some new details on the innovative new engine, which Infiniti is calling VC-T, for Variable Compression Turbo, after the luxury brand offered a prototype test drive. We wrote extensively about the complicated technology underpinning the new engine last year. It's the latest novel development that could represent a range-extender, if you will, for the embattled internal combustion engine in an era when automakers and governments are shifting their focus to electric vehicles. The VC-T is a new inline-four, 2.0-liter that combines the power of a high-performance turbo gasoline engine with the torque and efficiency of an advanced diesel engine, but without the latter's notorious emissions. It features the ability to seamlessly raise or lower the stroke of the pistons in the combustion chamber, depending on the driving conditions it detects and inputs from the driver, to select the best compression ratio—anywhere between 8:1, typical for high-performance engines, and 14:1 for high efficiency. In essence, it delivers the performance of a V6 but is much more efficient, with improved fuel efficiency of between 10 to 15 percent with its best competitors, per Car and Driver.

It's also quieter, more lightweight and compact than V6 engines with comparable power outputs, estimated at 268 horsepower and 288 pound-feet of torque. In a prototype test drive, Car and Driver writes that the engine "felt very conventional" and responsive, with strong and smooth acceleration. "The only indication you have that the compression ratio is changing is from an indicator in the instrument cluster next to the boost gauge." The engine is expected to deliver fuel economy gains of 27 percent in combined city-highway EPA rating over the outgoing QX50, which had a 3.7-liter V6. The 2019 model, fitted with the VC-T, should get about 26 mpg in combined fuel economy, and it will get to 60 mph almost one second faster than its four-cylinder counterparts, Nissan's chief powertrain engineer, Shinichi Kiga, told Automotive News. The VC-T engine is the result of 20 years of development spanning more than 100 prototypes and around 300 patents at Nissan.

2023 Infiniti QX50 gets new Sport trim and more

The Infiniti QX50 is a perfectly fine SUV with attractive styling and great standard features. Perhaps its most significant fault is that its rivals exist, as the BMW X3, Audi Q5 and Cadillac XT5 all do the same things, just as well (better, in some cases), and for less money in higher trims. Even so, the QX50 is worth a look if you’re in the market, and the automaker just updated the SUV with a new trim level, better standard features and a new maintenance plan. Infiniti offers five QX50 trims for the 2023 model year: Pure, Luxe, Sport, Sensory and Autograph. The base Pure trim starts at $40,300, and pricing reaches $57,350 for the top trim. Buyers can opt for AWD in lower trims for a $2,000 upcharge, and the Autograph trim adds AWD as standard equipment. Infiniti Premium Care is standard for all QX50s sold in the United States, which includes oil changes, inspections and tire rotations for up to three years. The headline change for 2023 is the new Sport trim. It gets dark-painted 20-inch wheels, unique badging and gloss-black exterior trim. Inside, the Sport adds semi-aniline leather upholstery and a 12-speaker Bose audio system. Those upgrades build on the Luxe trim, which starts at $43,600 and brings most of the goodies the base Pure trim forgets. That means standard wireless charging, remote start and rear passenger alerts. All QX50s get a decent suite of advanced driver aids, including forward automatic emergency braking, pedestrian detection, rear automatic braking, blind spot monitoring, lane departure warnings and automatic high beams. The 2023 QX50 is too new to have received complete crash test results, but its predecessor scored “Good” in crash tests and “Superior” for front crash prevention systems.
