Fernando Alonso testing the R28 at Valencia on January 23, 2008.
Similarly to Honda, Renault arrived at Valencia with their contender a week before its official launch, giving the first laps of the R28 to Fernando Alonso on January 21, 2008.[1] The car was officially launched on January 31, 2008 at Renault's communications headquarters in Boulogne-Billancourt, on the banks of the Seine in south-west Paris.[2] Renault unveiled rookie Nelson Piquet Jr. as Alonso's team mate for the 2008 season, and confirmed Lucas di Grassi,[3]Romain Grosjean[4] and Sakon Yamamoto[5] as their official test drivers.
The car carries a similar livery and sponsorship to 2007: ING are still the title sponsor, but Pepe Jeans has now been added as a sponsor, along with returnee Spanish insurance firm Mutua Madrileña. Mutua Madrileña had been a sponsor of the McLaren-Mercedes team in 2007, but chose to follow Alonso when he left McLaren after only one year due to Alonso's personal sponsors.[6]
2008 season
Testing
Renault made strong progress throughout the early 2008 testing schedule, with Alonso consistently at the top end of the timesheets. The Spaniard has commented that the team are "able to keep improving our understanding of the Bridgestone tyres, and also the new way of setting up the car with no traction control or engine braking".[7] The team made some improvements at a later test in Jerez, despite difficult windy weather conditions.[8]
On April 9, 2009, during Renault's promotional tour in Dubai, Mohammed Ben Sulayem was invited to test drive the Renault R28 at the Dubai Autodrome. 100 meters after the start, he lost control of his car and crashed into the pit wall. The car was destroyed, but Ben Sulayem survived uninjured.[10]
