Race Recap: 2015 Canadian F1 Grand Prix is better behind the front

As of Saturday afternoon in Montreal, Canada, it was all about the number four. Lewis Hamilton put his Mercedes-AMG Petronas on pole position for the fourth time at the Circuit Gilles Villeneuve, and now his tally of pole positions matches his race number: 44. Nico Rosberg lines up beside him, which is the fourth time that particular one-two combo has occurred this season. Ferrari spent three engine development tokens to try and close the gap to Mercedes, Kimi Raikkonen making the most of it with third position on the gird. His teammate Sebastian Vettel got the worst of it, however, when the MGU-K unit failed during Q1, leaving him 160 horsepower down and out at the first hurdle. Valtteri Bottas put a revitalized Williams on the grid at fourth, ahead of a Lotus lockout of the third row with Romain Grosjean leading the way in fifth, Pastor Maldonado just beside. Nico Hulkenberg got the first Sahara Force India into seventh – the team is still waiting on the upgraded B car that should be available for Austria – ahead of Daniil Kvyat in the first Infiniti Red Bull Racing and a "pissed off" Daniel Ricciardo in the second Red Bull. Sergio Perez made it two Force Indias in the top ten, a welcome result from a team performing below expectations of late. When the lights went out, at the very front it was much ado about not that much at all. Hamilton got away clean and stabbed across the track to close the door for Rosberg, giving Raikkonen a chance to take the inside line into Turn 1 in an attempt to clear Rosberg for second place. That didn't happen, leaving the two Mercedes' to run in grid position for the entire race. It wasn't boring – Rosberg stayed close, rubber-banding the time gap to the leader from a little more than one second to just under four seconds, and Montreal is famous for race-rearranging safety cars and on-track incidents. But none of those occurred, so Hamilton crossed the line 2.285 seconds ahead of Rosberg after 70 laps to earn his fourth victory in Canada and the first-ever victory for the Brackley, UK-based Mercedes team. Valtteri Bottas drove his Williams to third position, the first podium place for the team this year and a welcome salve to heal the team's wounds from a poor showing in Monaco. That placing came courtesy of being in the right place at the right time, which was not far behind Raikkonen when the Ferrari driver spun at the hairpin on Lap 28 after his first pit stop.

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.

2016 Infiniti Q50 Red Sport 400 First Drive

When the original Infiniti Q50 arrived to replace the long-lived G Sedan, our reaction was lukewarm. It lacked poise, refinement, and efficiency, and we hated the Direct Adaptive Steer system. We originally thought of this steer-by-wire system as, "technology for the sake thereof." Infiniti is hoping to address these shortcomings with the 2016 Q50. It gets a new and far improved version of DAS, and a 3.0-liter, twin-turbo V6 sits atop a diversified powertrain family. And at the top of the ladder sits this: the Q50 Red Sport 400. The Red Sport's all-aluminum 3.0-liter V6 pumps out 400 horsepower and 350 pound-feet of torque, the latter of which can be called upon between 1,600 and 5,200 rpm. That low-end thrust is what's most evident out on the road – everything from standing starts to freeway passes are effortless. It's actually kind of ferocious – the tachometer needle climbs relentlessly, and the engine feels strong and purposeful all the way up to its 7,000-rpm redline. It's a refined and smooth powerplant, too, which is a tremendous improvement over the old 3.7-liter V6. The sensations the revised Direct Adaptive Steer system delivers are comparable to the average, modern, electric power-assisted setup. The bigger accomplishment is Infiniti's second-generation Direct Adaptive Steering system. Owners can choose from three steering weights and three levels of responsiveness, but steering adjustments feel more incremental rather than dramatic, so you won't be jarred if you suddenly switch from an aggressive mode to a more comfortable setup. Computer wizardry still can't match natural feedback, but the sensations the revised Direct Adaptive Steer system delivers are comparable to the average, modern, electric power-assisted setup. Make no mistake, that's a huge improvement and it means DAS performs far better dynamically, especially when you ask for its most aggressive behavior. See the differences between the different modes in the video below. Even half-throttle situations in the standard drive mode required counter-steering. Direct Adaptive Steer feels perfectly fine during everyday driving. We spent about 75 percent of our time testing a DAS-equipped car, but hopped into a non-DAS model a the short, 20-mile drive back to our hotel. DAS felt more stable and easy to track down the road – it didn't require the constant, tiny steering inputs of the traditional system.
