Mercedes reserve driver Pascal Wehrlein set the pace as the 2014 season concluded at the Yas Marina Circuit in Abu Dhabi.
Wehrlein, sampling the title-winning Mercedes W05 Hybrid for the first time, posted a time of 1:42.624 during the afternoon session to trump Valtteri Bottas's lap from Tuesday's test day.
Wehrlein, 20, has raced for Mercedes in DTM this year and was confirmed as the squad’s reserve driver in Formula 1 in September, having conducted 30 days in the team’s simulator. He also racked up 500km of running in a 2012 car in Portugal.
Raffaele Marciello, who finished his maiden GP2 Season in eighth position, tested the Ferrari F14T for the first time and went second quickest at the end of the session to push Toro Rosso's Max Verstappen into third.
New Sauber signing Marcus Ericsson received his second day in the C33 and went fourth quickest, having racked up a best of 112 laps, ahead of Caterham driver Will Stevens.
Force India trialled an ‘info wing’ on its VJM07 and F3 backmarker Spike Goddard drove the car for the first time and went sixth quickest ahead of compatriot Daniel Ricciardo.
Three-time Grand Prix winner Daniel Ricciardo returned to the cockpit of his Red Bull RB10 for the final time but suffered a mechanical problem during the afternoon session.
Felipe Nasr received his final day of running in the Williams FW36 and the Brazilian was eighth quickest ahead of his move to a Sauber race seat for next season.
Lotus split its track time between a couple of 2014 junior series champions. F3 winner and Lotus junior Esteban Ocon took to the circuit in the morning while GP3 champion Alex Lynn sampled the E22 in the afternoon session. Lynn finished in ninth place, with Ocon rounding out the top 10.
McLaren-Honda’s challenging test concluded as Stoffel Vandoorne missed the morning session and appeared for just one lap before the interim car stopped on track during its second lap.
The car was ready to run prior to the start of the day’s action but the engine failed to fire up when the green light went on at the end of the pit lane.
Vandoorne completed just three laps on the first day of testing in the MP4-29H/1X1 due to electrical problems and fuel/data exchange issues.
