Button could only manage ninth on the in Australia where the new car was beset by handling problems including poor ride over the Albert Park circuit’s bumps.
But the car fared better on the smoother Sepang circuit and McLaren made some progress with their set-up. Button was on course for at least fifth place when a pit-stop problem ruined his race.
Button hailed the performance as a “massive turnaround”.
“Most of the race in Sepang we were quicker than the Lotus. Most of the race we were quicker than Ferrari. Who would have thought that five days before?
“We are still not where we want to be and we got a bit lucky with the circuit being so smooth which helped a bit but a lot is understanding where the downforce is.
“The car is still not perfected, it was really thrown together for Sepang.
“The great thing is there are so many cars that are competitive and taking points off each other, which is exactly what we need.”
Button pointed out that Sebastian Vettel made a weak start to the 2009 season yet came close to beating him to the title that year. Vettel failed to score in Australia and Malaysia yet finished just 11 points behind Button.
Adam Cianciarulo sweeps to second straight Pro Motocross 450 win
Adam Cianciarulo (450) and Dylan Ferrandis (250) swept both motos of their divisions Saturday in the Lucas Oil Pro Motocross Championship event at Spring Creek MX Park in Millville, Minnesota, significantly impacting the points standings.
“Man, what a dream come true,” Cianciarulo said. “I really wanted to go 1-1 last round at RedBud and had that silly mistake. Today, we got the job done and made it happen. Two consecutive victories in the 450 Class just feels really good. I just want to keep the ball rolling.”
With three rounds remaining, Cianciarulo is ranked second in the standings at a 15-point deficit to Zach Osborne, who won three of the first five rounds.
In the 250 standings, Dylan Ferrandis jumped ahead of Jeremy Martin (who won three consecutive events earlier in the season) by three points (257-254).
Ferrandis beat third-ranked RJ Hampshire in the first moto and nipping Martin by 0.4 seconds in the second.
“That was a difficult race in the second moto and the pressure was on,” Ferrandis said. “It was really good for me to have that battle and come out on top in the second moto. The championship is really close and I think that we were able to put on a good show for everyone today. Jeremy [Martin] and I have a good relationship I think and we congratulated each other and talked about the battle after the race.”
NEXT: The Lucas Oil Pro Motocross Championship will hold its seventh round Sept. 26 with the Geico Motorcycle WW Ranch National at Jacksonville, Florida.
