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.

2015 Belgian Grand Prix is a return to scheduled programming

With summer intermission over, the second half of the Formula One season commenced in the Belgian countryside at Spa-Francorchamps. After qualifying, it looked a lot like the first half of the season with just a few minor changes. Lewis Hamilton was even more dominant in his Mercedes-AMG Petronas than usual, regularly taking half a second out of his teammate in just the middle sector of the circuit. Teammate Nico Rosberg tightened it up a tad for his final hot lap, but Hamilton still took pole by 0.45 seconds ahead of Rosberg in second. With his Williams back at a power track, Valtteri Bottas got himself up to third, although more than a second behind Hamilton. Romain Grosjean in the Lotus in fourth had his best qualifying performance since his fourth-place grid spot at the 2013 US Grand Prix. This was a huge boon for Lotus, the team facing another financial issue off track that threatened to have its cars impounded as soon as they left the circuit. Grosjean had to have his gearbox changed before the conclusion of six races, however, so the five-spot penalty meant he'd actually line up ninth for the race. Sergio Perez put the Sahara Force India in fifth, where we're more used to seeing his teammate Nico Hulkenberg, just ahead of Daniel Ricciardo in the Infiniti Red Bull Racing in sixth. Felipe Massa got the second Williams in seventh, in front of the second Lotus of Pastor Maldonado in eighth. Then came the first and only Ferrari in the top ten, Sebastian Vettel qualifying ninth after a disappointing Saturday for the scuderia; teammate Kimi Raikkonen suffered gearbox issues and qualified way down in 16th. Carlos Sainz took tenth in the Toro Rosso. A new start procedure in Belgium meant drivers had to handle clutches on their own, without the engineers finely tuning bite points between the garage and the start line. That was in conjunction with another rule limiting the kinds of radio messages possible between engineers and drivers, aiming to put more of the car in the drivers' hands. After an aborted start when Hulkenberg's car quit while sitting on the grid, Hamilton made the most of the new procedure. His start wasn't amazing but he beat everyone else off the line, while those behind were alternately getting bogged down or leaping ahead. Midway through the first lap the top ten was Hamilton, Perez, Ricciardo, Bottas, Rosberg, Vettel, Maldonado, Grosjean, Massa, Marcus Ericsson. At the end of 43 laps, Hamilton would still be in the lead.

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.
