Infiniti Prototype 9 is a wonderfully beautiful EV grand prix car

Few automobiles are as elegantly beautiful as the open-wheel grand prix cars of the 1940s, '50s and '60s. The simple, slender shapes of these cars bear no extravagant flourishes or adornments. The purposeful design is what gave these cars their beauty, and it's these classic machines that inspired the new Infiniti Prototype 9. Teased earlier this week, this concept blends old and new, with classic lines hiding a modern all-electric powertrain. The Prototype 9 will make its full debut next week at the 2017 Pebble Beach Concours d'Elegance. Infiniti says the car was built around a simple idea: what would a 1940s Infiniti grand prix car look like? While the silver paint may be more German than Japanese, the design could easily be mistaken for an actual '40s grand prix car. Only the Infiniti-styled grille gives it away. Everything about it, from the thin bias-ply tires wrapped over center-locking wire wheels to the bulging screws around the driver's seat, is pitch perfect. Underneath that achingly long hood rests a prototype electric motor and battery from Nissan's Advanced Powertrain Department. The combo sends 148 horsepower and 236 pound-feet of torque straight to the rear wheels. That's good enough to send the svelte 1,962 lb car to 62 mph in just 5.5 seconds. Top speed is right at 106 mph. While speed may die off towards the top end, all that torque and a 43/57 front to rear weight distribution should make the Prototype 9 a riot on a small, tight circuit. There's only enough juice in the battery for about 20 minutes of flat-out racing. The handmade steel body rests on a steel ladder-frame chassis. The front suspension uses a leading-arm rigid axle with transverse leaf spring while the rear uses a De Dion axle, also with a transverse leaf spring. The Prototype 9 also uses old-school hydraulic rotary type dampers. There's no power steering and no brake booster for the four-wheel disc brakes. The car was designed and built by a number of different departments within Infiniti and Nissan. A simple sketch expanded as more and more designers and engineers wanted to have a hand in the project. The steel body panels were all shaped and hammered by hand. The bare cockpit is only adorned with a thin seat, three gauges, a few switches, a gear selector and the steering wheel. The gauges are set into a fixed aluminum hub in the center of the steering wheel.

2018 Infiniti QX80 Drivers' Notes Review | Big, brash and big

When it comes to body-on-frame, full-size SUVs, it seems every automaker has the same strategy. Offer one version as a more affordable, workman-like model, and another one as the plush luxury model. Ford has the Expedition and the Navigator, Toyota has the Land Cruiser and the LX 570, GM has the Tahoe and the Escalade. Over at Nissan, the pairing is the Nissan Aramada and the Infiniti QX80. We recently reviewed the Nissan version, and we just had a turn in the Infiniti. So how did the Infiniti fare against its proletarian twin? Read on to find out. Associate Editor Joel Stocksdale: So here's the thing about the Infiniti QX80: It's literally just a flashier Nissan Armada. As I sat down to write my thoughts, I took a second look at what I wrote about the Nissan-badged version, and I realized almost everything on my mind I already covered. The thing is enormous. Walking up to it, it seems like it might be an inch taller than me (5'11"). It's pretty wide, too, and the width is consistent all the way up. But it is still easy to drive with light steering and very good visibility. The 5.6-liter V8 sounds lovely and seems well-matched to the truck, and the transmission shifts smoothly and picks gears well. The real problem I see is that my feelings about the QX80's interior are nearly identical to those of the Armada. They're virtually identical, especially when comparing the higher trim Armadas. They have the same infotainment, the same buttons. There are a lot of buttons, too, scattered seemingly haphazardly and are difficult to use, especially with the very dated infotainment system. The dash design and shape of the wood are the same, and so is the steering wheel. The only things I could tell were really different were the shift knob, the gauge faces and the quilted leather seats. And Nissan offers a version of the latter on the Armada Platinum Reserve. I'm dwelling on this a bit because the Infiniti QX80 is not cheap. The four-wheel-drive one we had here in Michigan had a base price of $68,845. That's a few thousand more than the aforementioned Armada Platinum Reserve, and I don't see how the Infiniti is worth that extra money. It seems all you're getting is a flashier exterior, especially with the $2,800 22-inch wheels, and a more prestigious badge. I need more than chrome and badges to spend so much money. My recommendation is just buy an Armada.

A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.
