Le Mans, France - Former Formula One driver Kamui Kobayashi smashed the Le Mans lap record on Thursday as Toyota swept the front row in qualifying for the 24 Hour sports-car race and left Porsche trailing.
Kobayashi, sharing the No.7 TS050 hybrid car with Britain's Mike Conway and Frenchman Stephane Sarrazin, went round the Circuit de la Sarthe in 3m14.791s during the day's second session.
The time, at an average speed of 251.882km/h, was more than two seconds quicker than the previous record of 3m16.887s set by Switzerland's Neel Jani for Porsche in 2015 qualifying. It was also faster than German driver Hans Stuck's 1985 pole of 3m14.800s set on a shorter track with fewer corners.
Kobayashi had already put Toyota on provisional pole on Wednesday after lapping in 3m18.793s in the opening night session.
"Mike Conway told me the car was perfect, so I set off fully confident," said Kobayshi. "I had 100 percent confidence in the car and when you're in that frame of mind, you can do great things."
"It was an incredible lap, the car was amazing, and we went after it without any trouble whatsoever with traffic. It surpassed all our hopes. It's rare to be able to say this, but it was a perfect lap.
"When I saw the time as I crossed the line, I said to myself, wow!"
Only one Japanese manufacturer has won Le Mans, Mazda in 1991, and Toyota - five times runner-up - has made winning the world's greatest sports-car race its main motorsport target after losing to Porsche for the past two years.
The No.8 Toyota, driven by Britain's Anthony Davidson, Japan's Kazuki Nakajima and Switzerland's Sebastien Buemi, qualified second in a time of 3m17.128s with Nakajima at the wheel.
In an endurance race where pace is nothing without reliability, qualifying is more about bragging rights ahead of a gruelling weekend. Champion Porsche filled the second row, with Jani the fastest of their drivers in the No.1 919 hybrid car he shares with Germany's Andre Lotterer and Britain's Nick Tandy.
Porsche won the 2016 race after Toyota had victory snatched from its grasp by a last-lap power failure just as Nakajima had seemed destined to take the chequered flag in front of 263 000 spectators.
