2024 Infiniti Q50 prices up $475, start at $44,200

The Infiniti Q50, like some small geologic formation, carries its graceful, aged sculpture into 2024 fearless and unchanged. Whereas in 2023 Infiniti added a new interior color, included Infiniti Premium Care, and increased prices, 2024 only sees higher prices. MSRPs are up $400 and the destination charge rises $75 to $1,150, for an additional premium of $475. Starting sums including destination are:  Q50 Luxe: $44,200  Q50 Sensory: $49,900 Q50 Red Sport 400: $58,050  Every Q50 is powered by a twin-turbo 3.0-liter V6, the Luxe and Sensory trims making 300 horsepower and 295 pound-feet of torque, the Red Sport 400 making the eponymous 400 hp and 350 lb-ft. As standard, all send their power to the rear axle through a seven-speed automatic. Sending power to the front axle adds $2,000.  The Black Opal Edition Package that we expected to be of limited supply returns for 2024. Its black opal iridescent paint job shifts from black to blue to green to purple depending on the light and viewing angle. The paint is matched with satin black badging and an exposed carbon fiber trunk spoiler, adding $2,200 to the price of the sole trim it's available on, the Q50 Red Sport 400. The package traces its lineage to the legendary iridescent Midnight Purple II, a color introduced on the R34 Nissan Skyline GT-R in 1998, and counts recent reboots elsewhere in the Nissan range with the 2014 GT-R with a Midnight Opal paint job and the 2022 GT-R T-spec in Midnight Purple.    It's understandable that a brand built on premium and sporty offerings doesn't want to give up its last unabashedly sporty offering, but this seems like a natural time to again wonder what is the endgame for the Q50, the final car in Infiniti's U.S. lineup. Automotive News reported over the summer that Infiniti showed its U.S. dealers a fastback sedan called a "striking evolution" of the Q70 boasting a longer wheelbase and shorter overhangs, a full-width headlight and taillight, and a "sporty and Porsche-like" rear end. That's anticipated in 2026. Maybe then the Q50 will be allowed to go off somewhere and rest.

Porsche tops J.D. Power quality index as Korean brands soar

While complaints about infotainment systems remain a thorn in the side of automakers for J.D. Power's annual Initial Quality Study, there's a lot to celebrate this year. The average number of problems reported per 100 vehicles fell to 112 in 2015 – a three-percent improvement compared to 116 in 2014. The results of this year's survey are based on the responses of over 84,000 people about problems within the first 90 days of buying or leasing a 2015 model-year vehicle. For the third consecutive year, Porsche tops the rankings with an average of 80 problems per 100 vehicles. Although, that's slightly more than the 74 the German sportscar maker scored in 2014. "While the Japanese automakers continue to make improvements, we're seeing other brands, most notably Korean makes, really accelerating the rate of improvement," Renee Stephens, vice president of US automotive quality at J.D. Power, said in the study's release. In fact, Kia ranks as one of the biggest movers in this year's list. The Korean brand jumped to second place from seventh last year. The company had an average of 86 problems per 100 vehicles, a 20-point improvement. Third place went to Jaguar with an average of 93 problems reported, versus last year's second-place finish with 87 of them. Fourth place was Hyundai, and fifth-place Infiniti also earned a gold star for improvement with 97 issues per 100 vehicles – 31-points better than last year. Fiat still anchored the bottom of the list. However, its 161 problems this year is a lot better than the 206 in 2014. Ranked by nationality, Korean brands (Hyundai and Kia) are now leading the industry in initial quality with an average of 90 problems reported per 100 vehicles. According to J.D. Power, this is the first time Europe's figure beat Japan with 113 and 114 issues, respectively. The American brands also averaged 114. Whereas General Motors dominated last year, the segment awards are spread out in 2015. GM, Hyundai, Nissan, and Volkswagen Group are all tied with four models each earning prizes.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
