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.

At long last, Infiniti plans a production EV

After years of false starts, it appears that Nissan's Infiniti division will finally launch a production electric car in 2019 and debut it as a concept in January at the North American International Auto Show in Detroit. Details at this point are scant, but Infiniti Executive Design Director Alfonsa Albaisa told Autocar the EV would be an all-new electric-only vehicle based on a new platform. Citing the company's grand prix-inspired Prototype 9 racecar concept that was shown a few weeks ago at Pebble Beach, Albaisa said consumers would see "parts of the car in a different context" on the concept EV. The Prototype 9's all-electric powertrain was developed by parent company Nissan's Advanced Powertrain Department. The last we saw of any electric offering from Infiniti was way back in 2012 with the LE Concept sedan, which was supposed to show up in dealerships two years later. Those plans were initially postponed in 2013 and then again in 2015 amid doubts over EV sales projections and larger concerns over boosting overall Infiniti sales. The LE had a 24 kWh lithium-ion battery pack paired with a 100 kilowatt electric motor delivering 134 horsepower and 240 pound-feet of torque.

2019 Autoblog Technology of the Year finalists revealed

Every fall, we line up a range of new models with the latest and most compelling automotive technology from the past year. We test everything from semi-autonomous systems like Tesla's Autopilot to trick suspension setups like the Multimatic spool-valve shocks on the Chevy Colorado ZR2. We spend months paring down the list to a small group of contenders. After testing, dinner and healthy debate, we tally up the votes and name our winner. For Autoblog's 2019 Technology of the Year Award, our three finalists are the Cadillac CT6 with Super Cruise, the Infiniti QX50 with Variable Compression Turbo and the Mercedes-AMG E 53 with EQ Boost. Super Cruise is an advanced SAE Level 2 semi-autonomous system, though Cadillac (unlike some of its rivals) is reluctant to push that point. Cadillac would like you to think of this as an advanced driver assistance feature rather than a semi-autonomous system. Super Cruise allows completely hands-free highway driving. Thanks to a driver-facing camera, the system forces the driver to keep his or her eyes on the road even if hands are off the wheel. Although the CT6 is being discontinued, look for Super Cruise to make its way to other Cadillacs soon. VC Turbo is a little more complicated. Basically, Infiniti's 2.0-liter turbocharged inline-four can vary the compression ratio on the fly. In general, turbocharged engines are more efficient than naturally-aspirated engines when on boost, but can perform worse at low revs. VC Turbo allows for a best-of-both-worlds situation, increasing the compression at low revs and backing it off once the turbo spools up. The best part is that it does so seamlessly, with only a dash readout letting you know what's going on under the hood. Our third finalist is the EQ Boost 48-volt system in the Mercedes-AMG E 53. Like VC Turbo, EQ Boost does a lot just beneath the surface. Mercedes has developed a new turbocharged 3.0-liter inline-six and paired it with a small electric motor. While the car can't run on electricity alone, the motor helps improve both efficiency and performance, smoothing shifts and filling in low-end torque before the turbos spool up. Think torque fill, similar to a McLaren P1. Who can complain about better fuel economy and more torque? Look for the 48-volt system to make its way into most of the Mercedes-Benz lineup. The winner will be revealed next week on Autoblog, and we'll present the award Jan. 15 at the Detroit Auto Show. Related Video:
