Infiniti's new VC-T changes the rules of small turbocharged engines
Sun, Aug 14 2016The 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.
Autoblog's Matt Davis named Infiniti global product and brand communications director
Tue, 03 Jun 2014The door that separates automotive journalism and automaker PR swings both ways, and swings often as we see journalists move over to PR and vice versa. This time, however, it's one of ours.
That would be Matt Davis, longtime European correspondent for Autoblog and frequent contributor to numerous other publications including AutoWeek, Edmunds and Esquire. He was co-founder and longtime chairman of the World Car of the Year Awards, and serves on the jury for the International Engine of the Year awards as well. Matt has resided in Milan since 2001, writing for publications around the world in a number of languages, but will now be moving to Hong Kong.
That's where he will be taking up his new position as Global Director of Production and Brand Communications for Infiniti, which relocated its global headquarters to Hong Kong from Japan more than two years ago. In his new capacity, which he officially assumes on July 14, Davis will report directly to Infiniti's general manager of communications Stefan Weinmann.
2014 Infiniti Q50S
Mon, 03 Feb 2014Ten years ago, nearly to the day, I took delivery of a brand-new 2004 Infiniti G35 6MT. The sporty rear-wheel drive sedan, equipped with its throaty 260-horsepower V6, slick manual gearbox and limited-slip differential replaced my 2001 BMW 330i because the Japanese competitor touted a product that was roomier, better equipped, quicker and lower priced. The G35 trumped the German in nearly every measurable category - at least on paper.
The 2014 Infiniti Q50 is the direct descendant, albeit two generations later, of the car I owned a decade ago. It is dimensionally about the same size, but it has gained more than 300 pounds of mass thanks to numerous safety upgrades and technical innovations. The additional weight is largely dismissed by a larger and more efficient powerplant that delivers an additional 68 horsepower, a welcome arrival, but the manual gearbox that charmed enthusiasts has been pushed out of the picture by a mandatory seven-speed automatic transmission.
As it has in the past, Infiniti touts its all-new Q50 as a luxury sport sedan worthy of the title. Decades ago, impressive performance statistics may have sealed the deal. Yet there is much more to the assignment today, as the model must offer premium appointments, sophistication and engaging driving dynamics if it's going to entice and capture the next-generation of young, premium buyers - much like the G35 did for me ten years ago.
