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.

Infiniti-Red Bull Racing will seek a fourth title with the RB9 [w/video]

This is the car and the team that everyone wants to dethrone. The stability of this year's regulations means that the Infiniti Red Bull RB9 is a seriously honed RB8; however, that's a situation probably no other team would complain about seeing that the RB8 recovered from early stumbles and reliability issues last year to carry Sebastian Vettel to a third consecutive driver's title and the team to a third consecutive constructor's trophy.
The most noteworthy revisions to the car are the partial vanity panel that omits the driver cooling slot, the even narrower rear end - a feature of just about every car launched so far - and purple sidepods to showcase new title sponsor Infiniti. Adrian Newey, perhaps the most feared designer on the pit lane, said the nose and front wing could be changed relatively easily throughout the season, but he wanted to make sure to get the middle of the car - everything from the sidepods, back - as good as possible since they're more difficult to re-engineer. His track record leads us to believe he did just that.
Below are two videos, one of the making of the RB9, the other the launch at team headquarters in Milton Keynes.

Infiniti Q30 is the company's first small hatchback

Well, here it is. Despite every attempt to show us the car via teasers, Infiniti has made it to the week of the Frankfurt Motor Show before introducing the all-new Q30, the company's version of the jointly developed Mercedes-Benz A-Class hatchback and the first compact from the Nissan-owned luxury marque. The Q30 will be available with a wide and varied array of gas and diesel powertrains for its appearances in other markets. There will be two 1.6-liter gas engines, in 120-horsepower and 154-hp varieties, and two diesels. The oil-burners, which will not be coming to the US, displace 1.5 liters and 2.2 liters, respectively. As for North America, the Q30 will follow in the footsteps of its Mercedes cousins, the CLA- and GLA-Class, and offer a single 2.0-liter, turbocharged four-cylinder with 208 horsepower and 258 pound-feet of torque. Although it displaces just as much as the CLA's 2.0-liter turbo and matches that car's output, enthusiasts will appreciate the six-speed manual transmission being offered alongside the Mercedes seven-speed, dual-clutch automatic. Say what you will about its Mercedes roots, but Infiniti's decision to offer a six-speed stick here in the US should be respected. The specific set of drive wheels isn't mentioned, although if the A-, CLA-, and GLA-Class are any indication, the Q30 will offer standard front-wheel drive and optional all-wheel drive. That's speculation on our part, but it's a logical assumption. The Q30 has retained the A-Class' front McPherson struts and rear multi-link suspension arrangement. But while it uses an identical design, Infiniti has tuned the shocks to its own specification. Depending on trim, the Q30 will ride on either 18- or 19-inch wheels. Speaking of those trims, there are three of them. The base trim is, um, basic – Infiniti spilled very little ink on the entry level model. In fact, aside from a few simple descriptions, equipment details on the other two trims are quite scarce. Choosing the Premium line will net you unique 18-inch wheels, LED fog lamps, heated door mirrors with body color housings, and twin chrome exhausts. The Sport brings a bit more to the table, making a functional change by lowering the ride height by 0.6 inches and fitting 19-inch alloys. Gloss black and dark chrome accents on the more aggressive front and rear fascias round out the exterior enhancements.
