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 shows off the new Q50 engine lineup in Chicago

Infiniti has a raft of engine options it's rolling out on the Q50 sedan. We found out about most of them a couple of months ago, but they're now confirmed in all their turbocharged glory. And they'll all be showcased this week at the Chicago Auto Show. The base engine is a 2.0-liter turbo four based on a Mercedes design and built at the new joint-venture engine plant in Tennessee. The engine produces 208 horsepower and 258 pound-feet of torque and will be available in the Q50 2.0t in either rear- or all-wheel drive. If those specs strike you as familiar, they're the same that you'd find in the Mercedes CLA250 and GLA250, both of which similarly make their 4Matic traction optional, but come standard in front- (not rear-) drive form. Above the four-pot sits a new 3.0-liter twin-turbo V6 that replaces the naturally aspirated 3.7-liter unit and will be available in two states of tune. The 3.0t model offers 300 hp and 295 lb-ft, but the performance model – dubbed Q50 Red Sport 400 – cranks it up to 400 hp and 350 lb-ft. Both versions come mated to a seven-speed automatic transmission and either rear- or all-wheel drive. The fourth powertrain options carries over in the form of the Q50 Hybrid, which still pairs a naturally aspirated 3.5-liter V6 to a 50-kW electric motor for a combined output of 360 hp. So if you like your sports sedan to come with some manner of assist, the Q50 offers plenty of choices. But if you're in the atmospheric camp, we're afraid you'll have to look elsewhere.

Red Bull keeps 2015 RB11 F1 challenger under wraps [UPDATE]

UPDATE: A previous version of this post suggested that Daniil Kvyat drove for Red Bull last year, when he actually drove for its affiliate team Toro Rosso. The text below has been updated with the correct information. This season will be one of new beginnings for Red Bull Racing. It's the first time in three years that it's not returning to the Formula One grid as defending champions, and without a world champion at the helm. But return it will to fight to regain its title, and this is the car with which it intends to do so. Revealed ahead of the season's first test session in Jerez this weekend, the new RB11 is wearing a bold camouflage "testing livery" of the type we're more accustomed to seeing on road-going prototype than on a racing car. Expect it to be replaced by the familiar blue, red and yellow by the time the season kicks off in Melbourne next month. Though the camouflage may keep certain aero developments disguised (if not altogether hidden) from the prying eyes of its rivals, the sloping nose mandated by the new regulations is plain to see. Otherwise the new RB11 is likely more of an evolution rather than a revolutionary clean-sheet redesign over the RB10 that returning hot-shoe Daniel Ricciardo drove last year, to be joined this season by Daniil Kvyat, who's been promoted from Toro Rosso to replace departing four-time champion Sebastian Vettel. Whether they can succeed, however, will largely depend on the engine. Red Bull has emerged as the primary partner for engine supplier Renault (sister company to the team's title sponsor Infiniti). In fact, after Lotus switched to Mercedes (and assuming Caterham doesn't make it back to the grid), Red Bull and its sister team Toro Rosso will be the only teams running Renault engines this season. The team says it has worked closer than ever with the French automaker to develop the Renault power unit, but chances are slim that they'll be able to catch up to Mercedes given the restrictions on engine development. If anyone can catch the Silver Arrows, though, it'll surely be Red Bull – the only other team to win a grand prix last season. THE RB11 REVEALED After an intensely busy off-season, Infiniti Red Bull's Racing's 2015 Formula One car, the RB11, has hit the track and begun testing at the Circuito de Jerez in Spain ahead of the new season.
