North American Car, Truck and SUV of the Year finalists revealed

The finalists for the 2023 North American Car, Truck and Utility Vehicle of the Year Awards were announced Thursday at the L.A. Auto Show. — The Acura Integra, Genesis Electrified G80 and Nissan Z made the cut in the car category. — The Ford F-150 Lightning, Chevy Silverado ZR2 and Lordstown Endurance advanced in trucks. — And the Cadillac Lyriq, Genesis GV60 and Kia EV6 advanced among utilities.  The winners will be announced Jan. 11 in Detroit.  The finalists underscored the industryÂ’s shift to electric vehicles, as all three utilities and two of the three trucks are EVs. The finalists were culled from a list of 26 semifinalists made up of three trucks, 10 cars and 16 utility vehicles that are new this year.  Notables that missed the cut include the Mercedes EQE, Subaru WRX and Toyota GR Corolla in cars; while the Honda CR-V, Kia Sportage and Rivian R1S were among the utes that did not advance. The three trucks are the only ones eligible this year and have advanced through the voting.  50 jurors who work for media outlets across North America vote three times over the course of the year to whittle down the field, which was originally 47 vehicles. Jurors also test the semifinalists at an October group event in Ann Arbor, Mich. The Honda Civic (car), Ford Maverick (truck) and Ford Bronco (utility vehicle) were the 2022 winners.

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.
