2024 New York International Auto Show Editors' Top 5 Picks

The New York Auto Show, like many other shows over the past few years, has shrunk. But it's still playing host to some interesting reveals, and we even got a few surprises this year. It was dominated by Nissan and Hyundai Motor Group products, but ones running the gamut from affordable cars to flagship SUVs. It was a strange situation of being both quite diverse in reveals, and not at all, depending on how you looked at it. Our favorites of the show are a clear representation of that. And another interesting observation, only one of the picks was significantly electrified. Scroll down to see the best reveals of the New York Auto Show,. 2025 Nissan Kicks View 10 Photos 5. Nissan Kicks "The Nissan Kicks has gone from a reasonably attractive and small crossover into something way more funky with cool textures, color combinations and some actual presence. Plus, it's more spacious, more powerful and has available all-wheel drive. If Nissan can keep the price nice and low to compete with similarly stylish and well-executed competition like the Chevy Trax, the company's got a real winner on its hands." – News Editor Joel Stocksdale InfinitiQX80-Z63-051 View 39 Photos 4. Infiniti QX80 "The QX80 wasn't technically shown at the New York Auto Show, but it was revealed just a week prior at Hudson Yards – accross the street, in other words. Frankly, I wasn't blown away by the initial photos, but I think it looks great in person. The attention to detail both outside and in seem appropriate for an SUV that Infiniti hopes to sell for six figures loaded up. I'm a believer." – Associate Editor Byron Hurd 2025 Kia K4 Live View 7 Photos 3. Kia K4 Sedan "The Kia K4 interior has way more style than anything in the compact car price range has any business having. Now, if we don't get the green interior option shown in the initial global reveal photos, I'm retracting several of my points here. Otherwise, wowza. I kept looking and looking at that K4 interior photo, and finding new, interesting details to admire. Oh, and the exterior is pretty cool, too, though I do prefer the hatchback in that regard." – Senior Editor, West Coast, James Riswick Genesis GV60 Magma Concept View 10 Photos 2. Genesis GV60 Magma "I am psyched to see Genesis show off a proper performance car. The “Sport” trims on its various models are sort of neat, but the Magma brand looks like the real deal.

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.
