Infiniti previews modified Q50 Red Sport 400 for SEMA

Infiniti sports sedans are having a bit of a renaissance these days thanks the dirt cheap prices of high mileage G35s and G37s. As such, it's a good a time as any for Infiniti to introduce an aspirational vehicle in the same lineage: a Q50 Red Sport 400 built for the 2023 SEMA Show. The Q50 is probably not a car you've given much thought about in recent years, as it's been hanging around largely unchanged since its introduction in 2014. Infiniti hasn't had a presence at SEMA for most of that time either. This year, the luxury brand has cooked up a Q50 Red Sport 400 loaded with aftermarket accessories for the Vegas extravaganza. The car was built to showcase products from the Infiniti Performance line accessories, which includes suspension bits like upper control arms, rear traction rods, endlinks and more. There's also performance brake pads and a cat-back exhaust with the Infiniti logo etched into the tip. The Q50 show car also adds more coolant into the cooling system with a thicker radiator, a billet-aluminum expansion tank and an auxiliary intercooler tank. Naturally, there's a cold-air intake too. The build was done in part with Mobil 1, who has filled the 400-horsepower twin-turbo 3.0-liter V6 with 0w-20 synthetic.  The most desirable parts of all might be the four lightweight Nismo LM-RS1 wheels. Measuring 19 inches in diameter and 9.5 inches in width, they are available in black, gray, or bronze. The purpose of all this, Infiniti says, is to let owners of the Q50 and Q60 (and older G37s and G35s) know that the company offers a line of parts for customization. It's not the first time Infiniti has tried something like this. Anyone remember the short-lived Infiniti Performance Line (IPL) from 2010? Infiniti's commitment to performance has always seemed half-hearted. Maybe this time it'll stick around for a bit longer.

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.

2024 New York International Auto Show Editors' Top 5 Picks

The New York Auto Show, like many other shows over the past few years, has shrunk. But it's still playing host to some interesting reveals, and we even got a few surprises this year. It was dominated by Nissan and Hyundai Motor Group products, but ones running the gamut from affordable cars to flagship SUVs. It was a strange situation of being both quite diverse in reveals, and not at all, depending on how you looked at it. Our favorites of the show are a clear representation of that. And another interesting observation, only one of the picks was significantly electrified. Scroll down to see the best reveals of the New York Auto Show,. 2025 Nissan Kicks View 10 Photos 5. Nissan Kicks "The Nissan Kicks has gone from a reasonably attractive and small crossover into something way more funky with cool textures, color combinations and some actual presence. Plus, it's more spacious, more powerful and has available all-wheel drive. If Nissan can keep the price nice and low to compete with similarly stylish and well-executed competition like the Chevy Trax, the company's got a real winner on its hands." – News Editor Joel Stocksdale InfinitiQX80-Z63-051 View 39 Photos 4. Infiniti QX80 "The QX80 wasn't technically shown at the New York Auto Show, but it was revealed just a week prior at Hudson Yards – accross the street, in other words. Frankly, I wasn't blown away by the initial photos, but I think it looks great in person. The attention to detail both outside and in seem appropriate for an SUV that Infiniti hopes to sell for six figures loaded up. I'm a believer." – Associate Editor Byron Hurd 2025 Kia K4 Live View 7 Photos 3. Kia K4 Sedan "The Kia K4 interior has way more style than anything in the compact car price range has any business having. Now, if we don't get the green interior option shown in the initial global reveal photos, I'm retracting several of my points here. Otherwise, wowza. I kept looking and looking at that K4 interior photo, and finding new, interesting details to admire. Oh, and the exterior is pretty cool, too, though I do prefer the hatchback in that regard." – Senior Editor, West Coast, James Riswick Genesis GV60 Magma Concept View 10 Photos 2. Genesis GV60 Magma "I am psyched to see Genesis show off a proper performance car. The “Sport” trims on its various models are sort of neat, but the Magma brand looks like the real deal.
