2021 Infiniti Q50 Red Sport 400 Road Test | Z engine preview

There isn’t much reason to take another look at the 2021 Infiniti Q50 Red Sport 400 on the surface. ItÂ’s largely the same sedan as it was when we drove it in 2016: powerful and stylish, but lacking in tech and polish. However, whatÂ’s under the hood is of far more interest to us today than it was just a year ago. ThatÂ’s because the 3.0-liter twin-turbo V6 powering this Infiniti is migrating over to the next Nissan Z car. Nissan announced that the production Z would get a 3.0-liter twin-turbo V6 not long after it revealed the Z Proto. There are no other twin-turbo V6s in NissanÂ’s arsenal but this one, meaning that the VR30DDTT engine in this Infiniti is destined for the Z — plus, there's photo confirmation. The big question remaining is: How new or different will it be? Its most potent state of tune is rated at 400 horsepower and 350 pound-feet of torque. ThatÂ’s a high number versus most other boosted six-cylinders, and perhaps most importantly, itÂ’s more potent than the 382-horsepower 2021 Toyota GR Supra 3.0. As weÂ’ll soon explain, though, numbers only tell part of the story. Transplanting the InfinitiÂ’s V6 into the next Z surely wonÂ’t be without challenges, either. Nissan is promising a six-speed manual in the Z. Meanwhile, this engine is exclusively paired with a traditional seven-speed automatic transmission in the Q50 and Q60. Nissan hitched this engine up with a manual in a 370Z SEMA show car years ago, but now it must devise a production car solution. ThereÂ’s also the question of whether Nissan will use the same seven-speed as the automatic option in the Z, or come up with something a bit more aggressive. The cost-efficient (and likely) solution would be reusing the seven-speed, not unlike the Supra's eight-speed traditional automatic.  Having all of this in mind, we set out to see how this engine sits today as a preview to the Z.  Going from the big, naturally aspirated VQ series V6 to a smaller twin-turbo V6 will bring about the obvious changes. The rabid and uncouth personality of the outgoing VQ is nowhere to be found in the sweet and smooth new engine. ItÂ’s not quite the silky, effortless BMW inline-six found in the Supra, but it brings an air of refinement and maturity that's simply not there in the current Z. And then thereÂ’s the torque. All 350 pounds of twist are available at 1,600 rpm in the Q50 Red Sport 400, which means the shove in the back would theoretically start just off idle.

2014 Infiniti Q50 priced at $37,605*

Infiniti has released full pricing information for its new 2014 Q50 line, which, as you're probably aware, replaces the well-liked G-series sedan. You may be wondering why this is news, as Infiniti announced pricing for its new Q50 sedan back in March. Apparently, though, those earlier prices applied only to the special pre-sell offer announced earlier this year and are only good for cars ordered by October 31, 2013.
Starting in November, base 2014 Q50 models with the automaker's 328-horsepower 3.7-liter V6 engine will begin at $37,605 (*including a $905 destination fee), while the sportier Q50S model will begin at $44,105. Adding all-wheel drive to either model costs an additional $1,800 over the standard rear-wheel-drive models. Regardless of engine or whether it's rear- or all-wheel drive, the Q50 comes with a seven-speed automatic transmission.
Opting for the 2014 Infiniti Q50 Hybrid will get the buyer a powertrain consisting of a 3.5-liter V6, a 50kW electric motor and a lithium ion battery that offers up a total power output of 354 hp and a highway fuel mileage rating of 36 miles per gallon, all for a starting price of $44,855, which includes the Premium group. The most expensive version of the new sedan is the Q50S Hybrid with all-wheel drive. That model carries an MSRP of $49,055.

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.
