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 Q50 Eau Rouge portends seriously powerful future sports sedan

"If we built this car I would expect it to feature over 500 horsepower and 600 pound-feet of torque."
Eau Rouge is a notoriously difficult turn at Belgium's Spa-Francorchamps Circuit that is capable of striking fear into the hearts of the most hardened driver. Naming a car after something so terrifying, therefore, strikes us as a rather poor idea.

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.
