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 QX60 adds three-year maintenance plan, higher price

Infiniti has published pricing information for the 2023 QX60. The second-generation crossover enters its second model year on the market with price increases across the board, a handful of new features and a three-year maintenance plan called Infiniti Premium Care. Buyers still have four trim levels to choose from. Pricing for the full range (including the $1,195 destination charge) is as follows: QX60 Pure: $50,395 ($2,520 more than in 2022) QX60 Luxe: $56,445 ($2,520 more than in 2022) QX60 Sensory: $59,795 ($2,420 more than in 2022) QX60 Autograph: $63,795 ($2,420 more than in 2022) Note that those figures correspond to the front-wheel-drive QX60. Motorists who want all-wheel-drive will need to pay and extra $2,000 regardless of trim. Small updates to the list of standard features complement the price hike. Every trim level gains a wireless device charger and a frameless rear-view mirror for 2023. The Luxe model gets gloss black trim on the rear bumper, while Sensory and Autograph trims receive gray trim. Heated front seats, 18-inch wheels, a 12.3-inch display for the infotainment system and a power-operated hatch continue to come standard. Infiniti Premium Care is the final addition to the QX60 line-up. Announced in June 2022, and offered on every 2023 Infiniti model, it's an integrated maintenance plan that includes three years' worth of engine oil and brake fluid changes, tire rotations, inspections, cabin air filter replacements, tire road hazard coverage, and, on some models, car rental assistance.

Infiniti parts ways with Red Bull Racing

The partnership between Infiniti and Red Bull Racing is done. The team announced that it will no longer run under branding from the luxury automaker and will drop the Infiniti name from its own. The shift is effective at the end of this year. Infiniti signed on as a sponsor of the Formula One team back in 2011 when Red Bull was at the height of its dominance and on the path to the second of four consecutive world championships. Two seasons later it stepped up to naming rights, with the team officially rebranded as Infiniti Red Bull Racing. But while the cars ran under motivation from the automaker's ally Renault, they stopped short of rebranding the engines as Infiniti's, leaving it in the unusual situation of being a title sponsor of (but not directly involved in) an F1 racing team. For next season, Red Bull will continue running the Renault power unit, albeit rebranded under the TAG Heuer name. In the process, the team will no longer have any branding from the French automaker or any of its associated brands. Meanwhile sister-team Toro Rosso is switching from Renault to Ferrari power for next season, while Lotus is prone to switch back to Renault engines and ownership. The French automaker also recently canceled its support of the feeder series known until now as Formula Renault 3.5. Infiniti has carried out only limited racing programs in its quarter-century history. Aside from the Red Bull partnership, it directly sponsored Sebastian Vettel up until his departure for Ferrari. The company also supplied IndyCar engines in the late 1990s, then sponsored the Indy Lights series for a few years. It recently helped a privateer team prepare a Q50 for the British Touring Car Championship, but otherwise hasn't had any top-tier factory racing programs to speak of. That makes it one of the few Renault Nissan Alliance brands (and Japanese automakers) not to actively participate in motorsports. Related Video:
