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.

Nissan Murano CrossCabriolet being phased out, no replacement planned

Over the years, I've been given many nicknames - a few of them have even been repeatable around small children. One such moniker is "Mr. Other Makes," a title given to me because of my predilection for sifting through eBay Motors seeking out automotive misfits and orphans. I've got a soft spot for the dreamers and automakers who take big chances on beancounter-enraging flights of fancy.
I count Nissan among that bunch, because for every safe-as-houses Altima or Sentra that rolls out of its factory gates, the Japanese automaker has often secreted away a little funding for white-space niche vehicles that any sane person wouldn't expect to pencil out. Some, like the Juke, have proven to be massive hits. Others, like the GT-R, have become icons. And then there are models like the Murano CrossCabriolet, a segment-bending mashup the likes of which we haven't seen since the AMC Eagle Sundancer.
Yesterday, upon revealing the new third-generation Murano ahead of its New York Auto Show debut, we reported "the writing appears to be on the wall" for the midsize crossover's novel convertible cousin. It appears we were right. Autoblog can now confirm that the CrossCabriolet will die at the end of this model year, and our source at Nissan tells us unequivocally, "there is no plan for a next-generation Murano CC."

2022 New York Auto Show Roundup | All the reveals, reviews, pictures

NEW YORK — In case you missed it, the New York Auto Show took place this year after being canceled in both 2020 and 2021 due to Covid. A lot of manufacturers showed up in force, but not everybody did. No matter, we were there, and we brought you news, photos and scoops from the floor throughout the show. All of our New York-related stories can be found at our central hub here, but if youÂ’d rather just get a small taste of everything in a quick and digestible format, keep scrolling. 2023 Kia Telluride and its new X-Pro trim Kia revealed the TellurideÂ’s first major refresh at New York, and it makes the three-row crossover a little bit more desirable without screwing up what we liked about it before. ThereÂ’s a new X-Line and X-Pro trim for someone who might want a little more off-road capability, and a number of tech improvements. Most notably, a newly-designed dash features new and bigger screens. 2023 Hyundai Palisade The TellurideÂ’s sister car from Hyundai was treated to a similar refresh. Like the Telluride, Hyundai gave the Palisade a slightly revised look, a new off-road trim (called XRT in the PalisadeÂ’s case), more tech inside and a new dash design with full-width air vents. If we had to choose, weÂ’re a little more impressed with the TellurideÂ’s refresh, as a number of us on staff actually prefer the pre-refresh Palisade styling over the new one. 2023 Jeep Wagoneer L and Grand Wagoneer L This one was inevitable. Jeep revealed the longer, roomier versions of its Wagoneer and Grand Wagoneer in New York, and theyÂ’re designated with an “L” at the end of their names. Total length grows by a foot, and the wheelbase goes up by 7 inches versus the standard Wagoneer models. Jeep has essentially allocated all this extra room to the cargo area, as it now offers a staggering 44.2 cubic-feet of space behind the third row. Besides the L, Jeep announced that its new Hurricane inline-six engine would find its first home in the Wagoneer. Efficiency gets a small boost, and power is more than sufficient at either 420 horsepower (standard output) or 510 horsepower (high-output version) from the twin-turbo I-6. Chrysler Airflow Graphite Concept The Stellantis party continues with Chrysler and its slightly revised Airflow. Re-styled for the New York market after initially debuting at CES in Las Vegas, the Airflow Concept gets new paint, changed accent colors, a slightly changed interior design and a new interpretation of the Chrysler logo.
