Infiniti Q50 steer-by-wire system took 10 years to develop [w/video]

Infiniti's Direct Adaptive Steering (DAS) is quite a novelty - the system employs no physical connection between the steering wheel and the front wheels under normal circumstances and instead relies on a computer, clutch and steering-angle actuator to guide vehicles down the road with input from the driver.
In our First Drive review of a 2014 Infiniti Q50 equipped with the system, we weren't overly impressed by the artificial feedback. But we can't help but be impressed with how long Infiniti spent on its development: a full 10 years, according to Autoline Daily in the video report below. A staggering 70 percent of the research and development time spent on DAS was devoted to getting the steering feel right, and unfortunately, our first impression suggests their results still leave something to be desired, as we found it lacked the sporty feeling a sport sedan should have.
The weight of DAS is comparable to that of a conventional steering system due to its complexity. For example, three ECUs are used in the first-generation DAS system to ensure there's never a loss of steering, but Infiniti is refining the technology and is working to simplify it to reduce weight. One day Infiniti hopes that only one ECU will be needed to control DAS. We just hope it doesn't take the Japanese automaker another ten years to get the steering feel right.

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.

Infiniti Q50 Eau Rouge gets the heart of a GT-R [w/video]

There has been ongoing talk of an Infiniti using the Nissan GT-R powertrain practically since the moment the Nissan's flagship sports coupe hit the road. While the rumors have gone back and forth over the years, they have never completely gone away. It seems Infiniti is finally turning an ear to the screams of its most vocal enthusiasts with an updated version of the Q50 Eau Rouge concept boasting a modified version of Godzilla's engine and all-wheel drive system debuting at the 2014 Geneva Motor Show. It's even taking things a step further and granting it a new, seven-speed transmission to replace the Nissan's six-speed.
The latest evolution of the Eau Rouge packs the same 3.8-liter, twin turbocharged V6 found in the GT-R but with a unique tune of 560 horsepower and 443 pound-feet (600 Newton-meters) of torque. That makes it 15 hp more powerful than the standard 2015 GT-R but gives up 20 lb-ft of torque. Power gets to the ground through the GT-R's all-wheel-drive system. Infiniti predicts that the Eau Rouge would sprint to 60 miles per hour in less than 4 seconds and on to a top speed of 180 mph.
According to Infiniti Communications Senior Manager Kyle Bazemore in an email to Autoblog, the modded GT-R powertrain was not the only choice for the Eau Rouge. It also considered "developing a high-power sports diesel" and hybrid versions with an electric supercharger. However, "this was the clear solution for this concept car," Bazemore said. Other than the drivetrain, the Eau Rouge in Switzerland is identical to the one shown in Detroit. Sadly, it is not confirmed for production; so we might not be getting the fabled Infiniti GT-R sedan any time soon. Still, we can hope.
