Formular 1 star, Fernando Alonso, will be the first man to test the new McLaren car as the team begin their engine partnership with Honda. The Spaniard will drive the MP4-30 on the first day of the first pre-season test, at Jerez, Spain, on 1-4 February. Team-mate Jenson Button will test it on the second and fourth days, with Alonso driving on the third. Alonso, 33, who has joined from Ferrari, wrote on social media that he was ready to enjoy the challenge. McLaren are taking a similar approach to testing to Mercedes, for whom Nico Rosberg drives on the first day of testing before alternating with world champion Lewis Hamilton thereafter. McLaren will unveil their new car online on 29 January, a day before the wraps come off the 2015 Ferrari, also via the internet. Mercedes are to wait until the morning of 1 February before revealing their new W06. Williams on Wednesday became the first team to release images of their new car.
