Barcelona - Nico Hulkenberg ended Formula One's first pre-season test in Spain on a high for Renault on Thursday with the fastest lap so far by any of the new crop of cars.
The 31-year-old German, who holds the unwanted record of most races (156) without once stepping on the podium, lapped the Circuit de Catalunya in one minute 17.393 seconds in the late afternoon and on the softest tyre.
His car then stopped on the track, however.
Toro Rosso's Thai rookie Alexander Albon had led the lunchtime timesheets with a lap of 1:17.637 while Mercedes unlocked a little more pace and went faster than Ferrari.
British-born Albon, one of three Formula Two graduates making their F1 race debuts when the season starts in Australia on March 17, completed a whopping 136 laps - on top of 132 on Tuesday.
