The seventh round of the 2016 Formula One World Championship looks set to be most challenging circuit on power units of the season to date. The long straights demand maximum power for just over 60% of the lap. The longest straight on the circuit is the Droit du Casino at 1,064m and top speed will be in excess of 330kph, the highest speed seen this year so far.

There aren’t enough braking points on the circuit to allow the K to recover the full FIA allowable amount. This, along with the high fuel consumption at this track, makes for a
delicate balancing act during the race to stay within the 100kgpermitted fuel load, average fuel usage per lap is 1.48Kg, with the race taking place over 70 laps usage at this rate would exceed the permitted fuel limit by more almost 4KG. Drivers will be hoping for an early safety car period to avoid finishing the race in heavy fuel saving modes.
Renault will complete the roll out of the B-Spec power unit with both Renault Sport’s Jolyon Palmer and Red Bull Racing’s Max Verstappen having access to the unit in race conditions for the first time.
Speaking on the power unit Renault Sport’s Nick Chester commented:

 

“It’s a good step forward and we have it in both cars in Montréal. In Monaco we were able to benefit primarily from the improved driveability whereas Montréal is more a power track thanks to its straights following slow corners. This means we should really see the power unit stretch its legs.”

 

The nature of the circuit will put this upgraded unit under significant pressure, reliability will be a watch out over the weekend.
It is expected Honda and Ferrari will also introduce Power Unit upgrades over the Canadian Grand Prix weekend. With Mercedes coming to end of the cycle of it’s current unit in effect out of sequence to the other teams, expect the power output of teams to be a little close than normal over the weekend. Whilst this is unlikely to threaten the works Mercedes team, customers teams may fall further off the pace than otherwise expected.
