Renault and Williams show off their new Formula One cars before practice
session in Portugal.

ALGARVE MOTOR PARK. PORTUGAL -
Former champions Renault and Williams unveiled their 2009 Formula
One cars on Monday (January 19) before testing at the new Algarve Motor Park
circuit in southern Portugal.

Spain's double world champion Fernando Alonso and Brazilian Nelson
Piquet joined team boss Flavio Briatore in presenting Renault's R29 car to
photographers on a damp and cloudy morning.

Renault, eager to cut costs amid the global financial crisis, had
scrapped a planned launch at the Le Castellet circuit in southern France in
favour of a simple presentation at a regular test.

Offical Formula One tests are regulated by the Formula One Management
organisation and video footage of cars on test days can only be shown by FOM
rights holders, so worldwide coverage was limited to still photographs.

Williams also gave their car a low-key debut at the same test session,
rolling the Toyota-powered FW31 out of the garage for a brief photo-call
before German test driver Nico Hulkenberg took it out on track for the first
installation laps.

The British-based team are hoping major rule changes this season will
allow them to climb back up the standings after a disappointing 2008 saw them
slip to eighth overall.

McLaren, who will have world champion Lewis Hamilton at the wheel on
Wednesday, and Toyota were also testing their new cars at the Portuguese
circuit after launches last week.

Switzerland's Sebastien Buemi, the 20-year-old who will be the youngest
driver on the starting grid this season, was testing for Toro Rosso after
being confirmed by the Ferrari-powered team earlier this month.
