Canadian Grand Prix driver ratings

6 NICO ROSBERG
Mercedes F1 W06

Start: 2nd
Finish: 2nd
Strategy: 1 stop (super-soft/soft)

Rating: 7

Rosberg arrived in Montreal with the psychological momentum of two wins on the bounce, but he was derailed by a bad set of tyres in qualifying and wound up well adrift of team-mate Lewis Hamilton.

When Hamilton nailed the start Rosberg was consigned to a watching brief, and he needed more patience when his brakes started to overheat. Although Rosberg got within DRS range a couple of times late-on, Hamilton always had enough in hand to respond.

44 LEWIS HAMILTON
Mercedes F1 W06

Start: 1st
Finish: 1st
Strategy: 1 stop (super-soft/soft)

Rating: 8

The world champion began the weekend by telling the world the disaster of Monaco was well and truly behind him and then drove like it too. Hitting the wall in the wet in free practice was a minor blip; messy driving in a truncated final practice session potentially disastrous.

But Hamilton once again pulled the rabbit from the hat at the crucial moment, taking the 44th pole of his F1 career comfortably in the end. Victory after that was pretty much a formality.

3 DANIEL RICCIARDO
Red Bull-Renault RB11

Start: 9th
Finish: 13th
Strategy: 1 stop (super-soft/soft)

Rating: 5

Ricciardo said the aim for Red Bull this weekend was to get through the grand prix without having to take a grid penalty for an engine change. It managed that at least, but last year's Canadian GP victor was furious with the RB11's lack of pace here, declaring the team lost when trying to improve the car.

He banged his head against a wall (in his own words) in the race, finishing more than 33s adrift of team-mate Kvyat. He suspects something is seriously awry with his chassis.

26 DANIIL KVYAT
Red Bull-Renault RB11

Start: 8th
Finish: 9th
Strategy: 1 stop (super-soft/soft)

Rating: 8

Buoyed by his excellent result in Monaco last time out Kvyat was on good form again here, clearly feeling the benefit of another reliable and incident-free run through free practice.

He outqualified his team-mate for only the second time this season and did as well as could reasonably be expected in the race, keeping ahead of Perez's Force India and repelling a late challenge from Grosjean's penalised Lotus to grab two championship points.

19 FELIPE MASSA
Williams-Mercedes FW37

Start: 15th
Finish: 6th
Strategy: 1 stop (soft/super-soft)

Rating: 9

Massa's weekend started eventfully as he argued over driving standards with Max Verstappen in front of the world's press, and it got more eventful still when a faulty fixing in his Mercedes engine's turbo wastegate robbed him of boost and limited him to the 17th fastest time in qualifying.

Penalties for Verstappen and Sebastian Vettel boosted him a couple of place before the start, though, and he produced an excellent recovery drive into the top six.

77 VALTTERI BOTTAS
Williams-Mercedes FW37

Start: 4th
Finish: 3rd
Strategy: 1 stop (super-soft/soft)

Rating: 9

Bottas felt Williams should be back to its Ferrari-bothering best on this type of circuit and qualified within a tenth of fellow Finn Kimi Raikkonen to set up a rematch of their Spanish Grand Prix duel last month.

He was hanging on as best he could in the race, against a faster car, and gratefully accepted the gift of a first podium finish of the season when Raikkonen's new Ferrari engine went wild exiting the hairpin.

5 SEBASTIAN VETTEL
Ferrari SF15-T

Start: 18th
Finish: 5th
Strategy: 2 stops (super-soft/soft/soft)

Rating: 8

Vettel hoped Ferrari's upgraded engine would allow him to put more pressure on the pair of silver bullets at the front, but his challenge was derailed by a grid penalty for passing Roberto Merhi under red flags in third practice and an ECU problem in qualifying, which meant he exited in Q1.

From 18th on the grid he charged into the top five after surviving a couple of close moments with other cars at the final chicane. If only he'd started further up.

7 KIMI RAIKKONEN
Ferrari SF15-T

Start: 3rd
Finish: 4th
Strategy: 2 stops (super-soft/soft/super-soft

Rating: 7

Everyone wanted to know whether Raikkonen had done the qualifying homework set for him by team boss Maurizio Arrivabene after Monaco. His form suggested he had by being best of the rest on Saturday, but Vettel's problems mean the jury is still out on how fast Raikkonen really was.

He wasn't quick enough to challenge Mercedes in the race either, but would have finished on the podium certainly but for a bizarre spin caused by a sudden burst of torque from his engine.

14 FERNANDO ALONSO
McLaren-Honda MP4-30

Start: 13th
Finish: Retired
Strategy: (super-soft/soft/retired)

Rating: 7

Alonso expected a difficult weekend on a circuit that demands pure power more than anything else. He had to change his engine after practice two, forcing him to miss most of Saturday morning.

He shrugged off the drama to split the Saubers in qualifying (about par for the course) and gained a place before the start thanks to Verstappen's grid penalty. He felt excessive fuel saving requirements made him look like an amateur driver in the race. An exhaust problem put him out of his misery.

22 JENSON BUTTON
McLaren-Honda MP4-30

Start: 20th
Finish: Retired
Strategy: (soft/super-soft/retired)

Rating: 6

Honda brought an updated engine to Canada, believed to include revisions to the turbo and MGU-H, but the ERS on Button's failed during practice three and forced him to miss qualifying for the second time in four races.

When damage was discovered to the turbo and MGU-H (necessitating replacement) he copped a drivethrough penalty before the race had even started. He took that on lap one and then droned around until his exhaust failed too.

11 SERGIO PEREZ
Force India-Mercedes VJM08

Start: 10th
Finish: 11th
Strategy: 1 stop (super-soft/soft)

Rating: 5

Perez followed up an excellent drive in Monaco last time out with a weaker performance here, and he was comprehensively shaded by his team-mate. He felt incorrect tyre pressures exaggerated the 0.724s gap to Hulkenberg in qualifying, but he didn't fare much better in the race.

The Mexican spent most of it stuck behind Kvyat's Red Bull as he struggled with understeer and then fell away badly in the closing stages when fuel and tyre management became marginal.

27 NICO HULKENBERG
Force India-Mercedes VJM08

Start: 7th
Finish: 8th
Strategy: 1 stop (super-soft/soft)

Rating: 7

Hulkenberg felt the lap he pulled out of his sleeve was his best of the year to beat both Red Bulls in qualifying, though he could have been another tenth and a half further clear had he strung everything together.

He jumped Maldonado with an aggressive first-lap move in the race, but fell back behind after going long on his first stint. A spin at the chicane under attack from Vettel was unnecessary, but he wouldn't have finished any higher without it.

33 MAX VERSTAPPEN
Toro Rosso-Renault STR10

Start: 19th
Finish: 15th
Strategy: 1 stop (soft/super-soft)

Rating: 5

Verstappen took a lot of heat from rivals for refusing to back down over his Monaco collision with Romain Grosjean, and the need to fit a fifth engine to his Toro Rosso after Friday practice meant his five-place grid penalty for that incident became a 15-place one.

He served eight of those after qualifying 12th and the rest in the form of a 10s penalty at his pitstop. He had the faster tyre for the final stint but got stuck behind Ericsson's Sauber.

55 CARLOS SAINZ JR
Toro Rosso-Renault STR10

Start: 11th
Finish: 12th
Strategy: 1 stop (super-soft/soft)

Rating: 7

Toro Rosso was not competitive here, struggling with the power deficit of the Renault engine and the concurrent need to run minimal downforce to compensate on this circuit. Sainz did well to qualify 11th in the circumstances, but he would have just bumped Ricciardo out of the top 10 in Q2 had he strung all his sectors together.

He expected the toughest race of the season and got it. Drove decently, but points were never on the cards.

8 ROMAIN GROSJEAN
Lotus-Mercedes E23

Start: 5th
Finish: 10th
Strategy: 2 stops (super-soft/soft/soft)

Rating: 6

Grosjean looked quick in practice and felt a pitlane mix-up with his team-mate ahead of their final Q3 runs cost him a shot at third on the grid, but in reality fourth was the maximum possible.

Lotus's race pace was weaker, but seventh went begging to misjudged move on Will Stevens during lappery that earned Grosjean a time penalty and necessitated an extra pitstop. The team felt he should have repassed Kvyat's Red Bull before the flag.

13 PASTOR MALDONADO
Lotus-Mercedes E23

Start: 6th
Finish: 7th
Strategy: 1 stop (super-soft/soft)

Rating: 7

Maldonado has a terrible finishing record in 2015 so far, but starting sixth (his highest grid position since his 2012 season with Williams) offered hope of reversing that trend here.

For once he kept his nose clean and stayed out of trouble to record his best finish for Lotus. He made an early stop to repass Hulkenberg and impressed the team with a 53-lap marathon on the soft tyre. Seventh was a just reward for recent good driving.

28 WILL STEVENS
Marussia-Ferrari MR-04

Start: 17th
Finish: 17th
Strategy: 2 stops (soft/super-soft/super-soft)

Rating: 6

Following a first defeat of the season to his team-mate in Monaco, Stevens reckoned he would be back on top at this race. He felt less comfortable with the car here than at previous events and was shaded by 0.024s by Merhi in qualifying.

He thought he could reassert himself in the race, though, and got ahead early on, but suffered a slow pitstop and trailed Merhi by 3s when Grosjean spoiled the fun.

98 ROBERTO MERHI
Marussia-Ferrari MR-04

Start: 16th
Finish: Retired
Strategy: (soft/super-soft/retired)

Rating: 7

Signs Merhi is finally getting to grips with the MR-04 were illuminated by a strong drive. He felt an engine change for both cars eliminated a straightline speed deficit to Stevens, and persisting with a theoretically worse front wing configuration is working for him.

He edged Stevens on Saturday with a kamikaze effort into the final chicane, and having started ahead for the first time this year was on course to finish ahead too when his car broke a driveshaft.

9 MARCUS ERICSSON
Sauber-Ferrari C34

Start: 12th
Finish: 14th
Strategy: 1 stop (super-soft/soft)

Rating: 6

Ericsson has been comprehensively shaded by his rookie team-mate recently but he was much stronger here. He abandoned an experimental damping and brake set-up after practice one and was then usually flirting with the outskirts of the top 10.

The Swede should arguably have split the Toro Rossos in Q2, though Verstappen's penalty made this redundant. He felt points would be on in the race but they weren't. Too slow around his pitstop to stay ahead of Sainz, he at least kept one Toro Rosso behind.

12 FELIPE NASR
Sauber-Ferrari C34

Start: 14th
Finish: 16th
Strategy: 1 stop (super-soft/soft)

Rating: 4

Nasr has been driving extremely well recently but blotted his copybook with a bad shunt on the back straight in final practice, after accidentally opening his DRS while weaving to warm up his tyres. Sauber did a great job to repair the car for qualifying, but Nasr didn't string it together in Q2 so wound up 0.358s adrift of his team-mate.

He was slow in the race too, hampered by a lack of power and overheating brakes. A race to forget.
