The yin and yang of the 2017 Infiniti Q50 Red Sport 400

When we first drove the Q50 Red Sport 400, Infiniti had the car out at a prepared slalom-and-cone course in a large, open parking lot. The car was stacked up against another Q50 without the Direct Adaptive Steer steer-by-wire system, and the course was designed to show that the DAS-equipped Red Sport 400 (it's a $1,000 option) required less steering input to master the same course. With all due respect to Infiniti, which is invested in this unfortunate system and has been working hard to revise it, the comparison doesn't make a lot of sense. The non-DAS Red Sport 400 has a steering ratio of 15:1 in RWD and 16.7:1 in AWD forms. The DAS system can vary between 12:1 and 32.9:1 in RWD and 11.8:1 to 32.3:1 in AWD flavors. At its extremes, the DAS system's ratio is vastly different than the fixed-ratio cars. So sure, with a super-quick steering ratio available, the DAS driver's going to do less work. It's all in the gearing. Does this mean it's better, that the steering feel is more natural, that it's easier to hustle quickly? The amount the driver saws at the wheel isn't an indication of that, necessarily. After a few days in a rear-drive Red Sport 400, I'm saying that the spooky disconnection between the driver and the front wheels would be a severe deficit to a driver on a real autocross course. It's not like the DAS system is choosing bad ratios within its range, it's just not supplying the feedback to make it enjoyable. Knowing what your front tires are up to is critical. I can hear you saying right now, "But what Q50 Red Sport 400 owners are going to autocross their cars?" Sure, but it was just a means to an end: showing off the DAS in a good light. And in that case, it probably did. The thing is, in isolation, not back-to-back with a non-DAS car with a slow steering ratio, the DAS system has the same issues it's always had: It simply doesn't feel natural. It doesn't feel intuitive. There doesn't seem to be any real advantage over a slightly quicker rack. I don't hear about people making buying decisions based on how much work they have to do sawing at the wheel, do you? So, that's one side of the Q50 coin – one that's hard to ignore if you're an enthusiast and steering feel is an important connection between you and the vehicle you just dropped a large hunk of change on, and will be spending a lot of your time in. The other is that there's a really compelling reason to drive a Red Sport 400: The 3.0-liter, twin-turbocharged V6 is a monster.

Nissan files civil suit against Ghosn, seeking $91 million in damages

TOKYO — Nissan filed a civil suit Wednesday seeking 10 billion yen ($91 million) in damages from the Japanese automaker's former Chairman Carlos Ghosn. Nissan filed the case in Yokohama District Court to recoup some of the monetary damages suffered, it said, “as a result of years of misconduct and fraudulent activity" by Ghosn. The claim was calculated by adding the costs from what Nissan called Ghosn's “corrupt practices,” such as rent for overseas property, use of corporate jets and payments to Ghosn's sister, as well as costs for the internal investigation into Ghosn's alleged wrongdoings. Representatives of Ghosn said in a statement they couldn't comment as they had yet to see the legal documents. “Nissan's maneuvers continue,” they said, while noting Nissan had claimed larger damages before. Ghosn, who led Nissan for two decades and saved it from near-bankruptcy, was arrested in Japan in November 2018, and charged with underreporting his future compensation and breach of trust in diverting Nissan money for personal gain. He was awaiting trial but skipped bail and showed up in Lebanon late last year. Japan has no extradition treaty with Lebanon, and he's unlikely to be arrested. A date had not been set for his trial, and Ghosn has said he was worried his ordeal would never end and he would not get a fair hearing. The bail conditions also barred him from seeing his wife. He has repeatedly lashed out at Japan's judicial system, where the conviction rate is higher than 99%. Japanese authorities recently issued an arrest warrant for Ghosn and three Americans, accused of helping his escape. Separately, they issued an arrest warrant for Ghosn's wife on suspicion of perjury. Ghosn has repeatedly said he is innocent, saying that the promised compensation had never been decided, and all the payments were for legitimate services. Wednesday's lawsuit by Nissan comes on top of the civil case Nissan filed against Ghosn in the British Virgin Islands in August last year. It alleged unauthorized payments, sought to regain a luxury yacht and pursued other damages, according to Nissan. Yokohama-based Nissan, which makes the Z sportscar, Leaf electric car and Infiniti luxury models, is also facing trial in Japan as a company in relation to Ghosn's scandal. It has indicated it will agree to any penalties. Nissan's reputation has been sorely tarnished over the Ghosn fiasco, and its sales have dropped. Nissan reports financial results Thursday.

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:
