JEREZ, Spain -- Jenson Button steered his repaired McLaren to the fastest lap on Wednesday, and Nico Rosberg helped Mercedes rebound from Lewis Hamiltons crash with the longest run on the second day of Formula One preseason testing. Otherwise, most teams continued to struggle with their new cars following a massive rulebook overhaul that includes a shift to a turbo engine and more sophisticated energy recovery systems. Four-time defending world champion Sebastian Vettel only managed eight laps around the Jerez track before Red Bulls engine maker, Renault, reported a malfunction and the team decided to call it quits. That gave Vettel a total of 11 laps to start the preseason. "Obviously weve not had a lot of running and have a few problems to sort out, but with such big rule changes it is usual to have some teething problems. Thats what tests are for, to sort those issues out," said Vettel, who now hands the wheel to new teammate Daniel Ricciardo for the remaining two days in southern Spain. An electrical problem had kept Button in the garage on Tuesday, but he was the first out on wet tires in the morning and after the asphalt had dried he set the benchmark lap time with 1 minute, 24.165 seconds. The former world champion is aiming to help McLaren bounce back from its worst season since 1980 after it didnt reach the podium last year. Rosberg led the eight-car field with 97 laps, a day after a front wing problem sent Hamiltons Mercedes flying into the barrier. Rosberg said the new Mercedes F1 W05 has little in common with its predecessor and compared its steering wheel to a "smartphone with all the information on it." After overnight rain, the sessions 9 a.m. start was delayed as a tractor worked its way around the track spraying more water on the already damp asphalt so teams could test Pirellis tires for wet surfaces. But by noon the sun had come out and the track was dry as forecasts of showers never materialized, leaving teams to run under normal conditions. All the teams are struggling to get their cars race ready in time for the season-opening Australian Grand Prix on March 16. They will have two more tests in Bahrain before heading to Melbourne. So far, they have combined for 424 laps across two days of testing. Last year, with the preseason starting after far fewer tweaks to the rules governing car design, drivers combined for more than 1,500 laps over the first two days here. Ferrari appears to be handling the new regulations the best. Kimi Raikkonen followed up his fastest lap time from Tuesday with the second-fastest lap on Wednesday, 0.647 seconds behind Button. Local favourite Fernando Alonso will drive for Ferrari on Thursday and Friday. McLarens promising recovery from Tuesdays no-show coincided with its hiring of Eric Boullier as its new racing director. Boullier joins a week after leaving rival Lotus, in a restructuring at McLaren that recently included luring back former team principal Ron Dennis as its new chief executive. F1 newcomer Marcus Ericsson came to a stop in his Caterham for the days third and final red flag. Sergio Perezs Force India had spouted smoke earlier after Esteban Gutierrez ended up in the gravel in his Sauber. F1s new rules include a shift to a 1.6-litre V6 turbo engine from last years 2.4-litre V8. They also affect the cars fuel limits, weight and body design. Ultra Boost Scontate .
