BMW 328i: it's 2.0-liter turbocharged four-cylinder gets called out for being more powerful and frugal than the six-cylinder it replaces.

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.

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.
