Top 10 photos of the week: 10 years ago

10. Tom Kristensen poses with the new Audi R10

We kick things off with Mister Le Mans himself. Remember the revolutionary R10 that made its public debut at Sebring in late winter 2005? This is it. And every Le Mans-winning Audi has been powered by a descendent of this diesel engine, offering abundant power and gobs of torque.

9. Water trucks wet the track for Michelin wet testing

We chose this image of Michelin water tankers spraying Jerez during December F1 testing because it perfectly illustrations how bonkers the spending was back then. Not only did Michelin pay to have an artificially wet track surface, but the whole test lasted for 10 DAYS. Yes, 10 days of testing. That's a lot of Euros spent.

One of the true gentlemen in F1, still in the prime of his career in 2005. As of the end of the 2015 season, he's now started 284 Grand Prix.

Sorry, but we just had to include Ryan Briscoe's curly locks.

6. Dario Franchitti in the No. 27 Klein Tools Jim Beam Dallara Honda Firestone that he will drive in 2006

Dario Franchitti before his Chip Ganassi days, seen here during the Andretti Autosport presentation.

Ah, the Toyota foray into F1. So much money spent, so little to show for it.

4. #58 Red Bull/ Brumos Racing Porsche Fabcar: David Donohue, Darren Law

The (slightly) better looking Daytona Prototype when the Grand-Am series began. It's important to note that the famed Brumos dealerships were sold a few weeks ago. So the Brumos name is essentially done.

Franck Montagny testing the Renault F1 at the very picturesque Jerez circuit. The Frenchman would go on to race in F1 for Super Aguri and Toyota, before heading to Peugeot for their 908 Le Mans project. Then he did commentary for Canal and did some IndyCar and Formula E before being banned from motorsport for using a banned substance. A lot can happen in 10 years.
