For the second year in a row, Mercedes is poised to wrap up the Formula 1 constructors’ championship in Sochi at this weekend’s Russian Grand Prix.

Mercedes won its first F1 teams’ title in Russia last year, having returned to the sport as a works constructor in 2010. When it last enjoyed such status in the 1950s, there was no championship for the teams.

Just as it did in 2014, Mercedes has dominated proceedings in F1 this season, winning all but three races and sweeping to eight one-two finishes to leave drivers Lewis Hamilton (pictured) and Nico Rosberg battling for the drivers’ title for the second straight year.

Now, Mercedes seeks the knock-out blow in the constructors’ title race by officially wrapping it up in Sochi this weekend.

To do so, the team must simply outscore rivals Ferrari by three points this weekend. The lead currently stands at 169 points, with 215 still on offer. After Sochi, there will be 172 remaining.

“We return to Russia with positive memories from last season, when the team sealed the first constructors’ title for Mercedes-Benz with a one-two finish,” team boss Toto Wolff said.

“A repeat performance in Sochi would be fantastic and this is absolutely the target – but we are under no illusions that it will come easy. The job is not done yet.”

The tire allocation for this weekend’s race could pose problems to Mercedes just as it did in Singapore, potentially allowing Ferrari to spoil the party and delay the victory celebrations at Brackley.

However, if the form book is to be trusted, Sochi could be playing host to another Mercedes party on Sunday night with a second world title in the bag for the Silver Arrows.

Cadillac, Acura battle for top speed as cars back on track for Rolex 24 at Daytona practice

DAYTONA BEACH, Fla. – The new hybrid prototypes of Cadillac and Acura battled atop the speed chart as practice resumed Thursday for the Rolex 24 at Daytona.

Chip Ganassi Racing driver Richard Westbrook was fastest Thursday afternoon in the No. 02 Cadillac V-LMDh with a 1-minute, 35.185-second lap around the 12-turn, 3.56-mile road course at Daytona International Speedway.

That pace topped Ricky Taylor’s 1:35.366 lap that topped the Thursday morning session that marked the first time the IMSA WeatherTech SportsCar Championship was back on track since qualifying Sunday afternoon that concluded the four-day Roar Before The Rolex 24 test.

In a final session Thursday night, Matt Campbell was fastest (1:35.802) in the No. 7 Porsche Penske Motorsports Porsche 963 but still was off the times set by Westbrook and Taylor.

Punctuated by Tom Blomqvist’s pole position for defending race winner Meyer Shank Racing, the Acura ARX-06s had been fastest for much of the Roar and led four consecutive practice sessions.

But the times have been extremely tight in the new Grand Touring Prototype (GTP) category that has brought hybrid engines to IMSA’s premier class. Only 0.9 seconds separated the nine LMDh cars in GTP in qualifying, and though the spread slightly widened to 1.378 seconds in Thursday’s practices with teams on varying strategies and preparation, Westbrook still pooh-poohed the importance of speeds.

“It’s always nice to be at the top, but I don’t think it means too much or read too much into it” Westbrook said. “Big fuel tanks in the GTP class this year, so you have no idea what fuel levels people are running. We had a good run, and the car is really enjoyable to drive now. I definitely wasn’t saying that a month ago.

“It really does feel good now. We are working on performance and definitely unlocking some potential, and it just gives us more confidence going into the race. It’s going to be super tight. Everyone’s got the same power, everyone has the same downforce, everyone has the same drag levels and let’s just go race.”

Because teams have put such a premium on reliability, handling mostly has suffered in the GTPs, but Westbrook said the tide had turned Thursday.

“These cars are so competitive, and you were just running it for the sake of running it in the beginning, and there’s so much going on, you don’t really have time to work on performance,” he said. “A lot of emphasis was on durability in the beginning, and rightly so, but now finally we can work on performance, and that’s the same for other manufacturers as well. But we’re worrying about ourselves and improving every run, and I think everybody’s pretty happy with their Cadillac right now.”

Mike Shank, co-owner of Blomqvist’s No. 60 on the pole, said his team still was facing reliability problems despite its speed.

“We address them literally every hour,” Shank said. “We’re addressing some little thing we’re doing better to try to make it last. And also we’re talking about how we race the race, which will be different from years past.

“Just think about every system in the car, I’m not going to say which ones we’re working on, but there are systems in the car that ORECA and HPD are continually trying to improve. By the way, sometimes we put them on the car and take them off before it even goes out on the track because something didn’t work with electronics. There’s so much programming. So many departments have to talk to each other. That bridge gets broken from a code not being totally correct, and the car won’t run. Or the power steering turns off.”

Former Rolex 24 winner Renger van der Zande of Ganassi said it still is a waiting game until the 24-hour race begins Saturday shortly after 1:30 p.m.

“I think the performance of the car is good,” van der Zande said. “No drama. We’re chipping away on setup step by step and the team is in control. It’s crazy out there what people do on the track at the moment. It’s about staying cool and peak at the right moment, and it’s not the right moment yet for that. We’ll keep digging.”
