To round-off Lewis Hamilton's winning season, McLaren's technology partner, ExxonMobil, presented him a final challenge: to design the ultimate 'Supercircuit'.

This fantasy race track is a combination of the toughest corners, chicanes and straights from Hamilton's favourite circuits around the world.

Hamilton planned a counter-clockwise circuit to be the definitive challenge – of both a driver's skills and a car's technological performance and stamina. Corners from Monaco, Interlagos, Silverstone and Spa-Francorchamps were slotted together to build his very own dream track: Lewis Hamilton's Mobil 1 Supercircuit.

Lewis explained "I wanted to create a circuit that would be challenging, exhilarating and enjoyable, but most of all somewhere you would love to have the chance to drive and provide the definitive test for any driver, in any car."

Lewis' Supercircuit starts on the home straight. As Hamilton waits for the red lights to go out, his heart rate climbs to 170bpm in anticipation of the start, for this is going to be no ordinary lap. Suddenly the lights go out; Lewis releases the clutch to let loose in excess of 750bhp through the rear wheels of his Vodafone McLaren Mercedes MP4-23. He accelerates towards Turn 1…

Turn 1

Turn 8, Istanbul Speed Park (5th gear, 260 kph, 5g)

A super-fast corner to begin the lap. Lewis withstands up to 5g for six seconds through this quadruple-apex left-hander, making it the longest and most physical corner on the Grand Prix calendar. The prolonged lateral loads place the engine's 300 moving parts under enormous stress and make it staggeringly tough on Lewis's neck muscles. "You have to attack this corner," says Lewis. "A bump at the first apex destabilises the car and you have to be very careful with how you position it, otherwise you can have a big oversteer moment."

Turn 2

Estoril, Magny Cours (5th gear, 200 kph, 3.5g)

Lewis's neck gets little respite because Estoril, another long and fast corner, comes next. It's a double-apex right-hander, through which Lewis has to plant the throttle in fifth gear without being able to see his exit. The track undulates through 180 degrees, leaving him on a high-speed rollercoaster. "Due to the high speeds," he says, "the car generates a lot of downforce through this corner and it feels planted to the track. It's great fun, but it's vital to make a good exit because a long straight follows."

Turn 3

130R, Suzuka (6th gear, 295 kph, 4g)

Lewis will have to wait until 2009 to drive a his Grand Prix race car at Suzuka for the first time, but such is the track's fearsome reputation that he has included two corners from the former Japanese Grand Prix venue on his Mobil 1 Superlap. 130R is a left-hander, so-called because it has a radius of 130 metres, and it's taken flat-in-top-gear with the engine screaming at its 19,000rpm limit. Lewis turns in smoothly and lets the car run wide over the smooth exit kerb to ensure that he scrubs off as little speed as possible.

Turn 4

Eau Rouge, Spa-Francorchamps (7th gear, 295 kph, 3.5g)

Like 130R, Eau Rouge is a section that's taken flat-out. The corner is in fact three bends, a left-right-left flick up the side of a hill, and it sees Lewis experience lateral and vertical g-forces. "This is one of the best corners on the calendar," says Lewis. "It's not difficult, but you're just excited all the way through it. As you climb up the side of the hill, there's a moment when all you can see from the cockpit is the sky. It's fantastic because you lose your stomach over the crest at the top." The car loses a bit of speed as it climbs the hill, but the whole section still takes only one second to complete at 305kph.

Turn 5

Tabac, Monaco (4th gear, 172 kph, 2.5g)

After a long period on full throttle, Lewis needs to be careful not to out-brake himself on this slippery section of street circuit. Tabac is the slowest corner on the lap, through which the Mobil 1 oil inside Lewis's Mercedes V8 engine travels faster than the car. "At the Monaco Grand Prix we have maximum downforce," says Lewis, "so the car feels planted to the ground. But with the barriers so close there is no room for error; you have to be very precise." Some slippery white lines at the exit can induce oversteer as Lewis tries to get back on the power, making it a great test of driver skill.

Turn 6

Turn 1, Suzuka (5th gear entry, 255 kph, 3.5g)
