Alonso and Michael Schumacher back in action
Tuesday at Jerez sees the start of the last Formula One test of the year before the teams take a well-earned break for Christmas. Some of them have had just one day off since last weeks session.
BMW Sauber, McLaren, Toyota and Ferrari will all be on track on the opening day, with the majority of their rivals expected to join proceedings from Wednesday. The test then runs until Friday, with a Michelin wet-weather session scheduled for Saturday.
Jacques Villeneuve displayed some impressive pace for BMW Sauber last week, and Nick Heidfeld will be hoping to carry on where his team mate left off. The new German-Swiss squad continue development of their 2006 V8 engine with a three-day programme.
There is not let up in Toyotas intensive test schedule. They remain the only team to have debuted their 2006 machine, the TF106 having already clocked up some impressive mileage, and they will be in action for a further three days this week, again working closely with new tyre suppliers Bridgestone.
World champion Fernando Alonso is due to make his first test appearance of the winter on Friday. The Spaniard will be using Renaults restricted V10 machine to give him a taster of 2006s V8 power levels. Conducting the rest of the teams four-day programme will be test drivers Heikki Kovalainen and Franck Montagny.
McLaren have a three-day programme scheduled, with Juan Pablo Montoya joining regular test driver Pedro de la Rosa. Meanwhile, Marc Gene and Felipe Massa will kick off Ferraris session, with Michael Schumacher expected to make an appearance later in the week.
