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 Q30 Concept might be the cleverest Q model yet

When we first got official word of the Infiniti Q30 Concept, the Japanese automaker said that the crossover's "harmonious contrasts and dissymmetric philosophy" would "make an emotional connection with customers spontaneously." Now, we might not be heads of design studios or directors of marketing departments, but we're pretty sure we can translate that to: "The production Q30 will compete with the Audi A3 and Mercedes-Benz CLA-Class."
In all seriousness (if we can say that of a concept car painted a sort of rose metallic), the Q30 concept looks fetching here in Frankfurt; its rather convoluted and flowing bodywork just carried off successfully because of its grownup hatchback proportions and, frankly, huge wheels. The Q30 could seemingly slot into the current, attractive Infiniti range of production cars and not look amiss (though we'd prefer a color palette that looks a little less like Grandma's sitting room sofa).

Cars with the worst resale value after 5 years

While the old saying that cars lose a massive chunk of their value as soon as they’re driven off the dealerÂ’s lot might not be entirely true these days, most new vehicles steadily lose value as they age and are used. iSeeCars recently released its latest study on depreciation, finding the models that lose value the fastest, and the list is packed with high-end nameplates. The vehicles that lost value the fastest over five years include: Maserati Quattroporte: 64.5% depreciation BMW 7 Series: 61.8% Maserati Ghibli: 61.3% BMW 5 Series Hybrid: 58.8% Cadillac Escalade ESV: 58.5% BMW X5: 58.2% Infiniti QX80: 58.1% Maserati Levante: 57.8% Jaguar XF: 57.6% Audi A7: 57.2% While sports cars, hybrids, and trucks dominated the list of slowest-depreciating vehicles, luxury brands accounted for all of the top ten fastest-depreciating models. iSeeCars executive analyst Karl Brauer also pointed out EVsÂ’ lack of representation on the slow-depreciating vehicles list, saying that thereÂ’s a disconnect between what automakers are building and what people actually want. The average five-year depreciation for all vehicles in the iSeeCars study was 38.8 percent. ThatÂ’s an almost 11% improvement over 2019Â’s figures, but some vehicle types perform worse than others. EVs depreciated 49.1 percent over five years, while SUVs dropped 41.2%. Trucks only fell 34.8% and hybrids 37.4%. Brauer noted that all vehicles depreciate slower than they did five years ago. Even so, EVs are not the best choice if youÂ’re looking for a vehicle that wonÂ’t feel like a ripoff when itÂ’s time to trade in. On the flip side, used EVs can present a stellar value, saving thousands over their new counterparts. Charging times and availability remain concerns for buyers in large parts of the country, but a heavily depreciated EV could be the used car value youÂ’ve been looking for. The same wisdom applies to used luxury vehicles, as the list above indicates. While new-car buyers shopping for luxury cars are set to see big depreciation during their ownership, that means the used car market is flooded with inexpensive used luxury cars. High repair costs and costly maintenance schedules are real issues that used luxury models face, however. Green Audi BMW Cadillac Infiniti Jaguar Maserati Car Buying Used Car Buying
