LEXINGTON, Ohio --- Marco Andretti led the afternoon practice and was fastest overall for the IRL's Honda 200, while Andretti Green Racing teammate Tony Kanaan was fastest in the morning and second overall on Friday.

But neither of them is looking forward to today's qualifying on the 13-turn, 2.3-mile road track at Mid-Ohio Sports Car Course.

Time trials on road and street circuits have become a grueling test this year, with the IndyCar Series adopting knockout-style qualifying.

The drivers are randomly divided into two groups before the start of the race weekend and each group starts qualifying by running for 30 minutes. The top six drivers from each group move on to a second round, a 15-minute session that cuts the qualifiers to the top six.

They then run 10 minutes in the Firestone Fast Six to determine the top starting positions for the next day's race.

"Our qualifying format is really tough on us," Kanaan said. "To make all three, by the time you go to the Shootout, you might shoot yourself in the head because you're so tired. ... It's killing us."

Andretti, 12 years younger than his teammate, agreed that the new qualifying format takes a lot out of a driver.

"It's almost like a race," the third-generation IndyCar star said. "I haven't been in the top six this year, but I've gotten to Q2 twice and just that is tough work."

FORMULA ONE: In Ockenheim, Germany, Lewis Hamilton dominated Friday's practice sessions for the German Grand Prix, putting McLaren on course for its first Formula One win in Germany in a decade.

Hamilton had the fastest lap at 1 minute, 15.025 seconds in the dry afternoon session at the Hockenheim circuit after leading the soggy morning session. Teammate Heikki Kovalainen trailed Hamilton at 1:15.666.
