2020 Infiniti Edition 30 models priced

The 2020 model year marks the 30th anniversary of Infiniti, and as announced back in August, the brand is rolling out specially tweaked Edition 30 models across the bulk of its lineup. We now have more details and pricing for the commemorative editions, which are available on the Q50 sedan, Q60 coupe, QX50 compact crossover, QX60 mid-size crossover, and QX80 full-size SUV. The Q50 Edition 30 sedan's starting price is $43,700 with rear-wheel drive and $45,700 is all-wheel drive. The Q50 Edition 30 is priced between the Luxe and Sport trim levels, but its equipment is closer to that of the Sport. Although it's $4,800 cheaper than the Sport, the Edition 30 adds full-speed adaptive cruise control, but it uses the smaller brake rotors of the Luxe trim and it skips the Sport's adaptive damping. Unique Edition 30 elements include dark-chrome 19-inch wheels and exterior trim, black mirror caps, and a black mesh grille. The Q60 Edition 30 coupe is offered as a $4,200 package for the Luxe trim level. Added to the $45,500 base price of the rear-wheel-drive Luxe coupe, and you get a starting price of $49,700 for the Edition 30. All-wheel drive is another $2,000. Exterior enhancements mirror those of the Q50 Edition 30. The Q60 Edition 30 package also adds navigation, an around-view monitor, power-adjustable steering column, memory settings, rear auto-braking, adaptive cruise control, heated seats and steering wheel, and a few lesser items. The QX50 Edition 30 compact crossover builds on the mid-level Essential trim level. It's sold as a package for $1,200 and includes adaptive cruise control, blind-spot intervention, lane-depature prevention, and adaptive front lighting, plus 20-inch dark-finish wheels, dark-chrome exterior accents, a body-color rear diffuser, and a black headliner. For the range-topping QX80, the Edition 30 is a package that adds $3,500 to the Luxe (base) trim level. Besides the dark-chrome exterior trim and dark-finish 22-inch wheels, it includes a rear camera mirror, lane-departure prevention, adaptive cruise control, blind-spot intervention, and a black headliner. On Infiniti's most popular vehicle, the QX60, full details of the Edition 30 are not yet available, but we're told the model will start at $50,850. That represents a $4,700 premium over the Luxe trim level, and includes the content of the ProAssist package as well as the Edition 30 design enhancements.

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.

The yin and yang of the 2017 Infiniti Q50 Red Sport 400

When we first drove the Q50 Red Sport 400, Infiniti had the car out at a prepared slalom-and-cone course in a large, open parking lot. The car was stacked up against another Q50 without the Direct Adaptive Steer steer-by-wire system, and the course was designed to show that the DAS-equipped Red Sport 400 (it's a $1,000 option) required less steering input to master the same course. With all due respect to Infiniti, which is invested in this unfortunate system and has been working hard to revise it, the comparison doesn't make a lot of sense. The non-DAS Red Sport 400 has a steering ratio of 15:1 in RWD and 16.7:1 in AWD forms. The DAS system can vary between 12:1 and 32.9:1 in RWD and 11.8:1 to 32.3:1 in AWD flavors. At its extremes, the DAS system's ratio is vastly different than the fixed-ratio cars. So sure, with a super-quick steering ratio available, the DAS driver's going to do less work. It's all in the gearing. Does this mean it's better, that the steering feel is more natural, that it's easier to hustle quickly? The amount the driver saws at the wheel isn't an indication of that, necessarily. After a few days in a rear-drive Red Sport 400, I'm saying that the spooky disconnection between the driver and the front wheels would be a severe deficit to a driver on a real autocross course. It's not like the DAS system is choosing bad ratios within its range, it's just not supplying the feedback to make it enjoyable. Knowing what your front tires are up to is critical. I can hear you saying right now, "But what Q50 Red Sport 400 owners are going to autocross their cars?" Sure, but it was just a means to an end: showing off the DAS in a good light. And in that case, it probably did. The thing is, in isolation, not back-to-back with a non-DAS car with a slow steering ratio, the DAS system has the same issues it's always had: It simply doesn't feel natural. It doesn't feel intuitive. There doesn't seem to be any real advantage over a slightly quicker rack. I don't hear about people making buying decisions based on how much work they have to do sawing at the wheel, do you? So, that's one side of the Q50 coin – one that's hard to ignore if you're an enthusiast and steering feel is an important connection between you and the vehicle you just dropped a large hunk of change on, and will be spending a lot of your time in. The other is that there's a really compelling reason to drive a Red Sport 400: The 3.0-liter, twin-turbocharged V6 is a monster.
