Probably Morgan Stanley.
A four-person team made up of Morgan Stanley employees came in first in the TeamSport City Slicker Challenge earlier this week, at TeamSport Tower Bridge, a brand new eco go-kart track.
And one member of the Morgan Stanley crew, Dave Pethers, actually managed to beat the fastest lap record set by Perry McCarthy, the original Stig, when he opened the track at the end of January (old record 50.2 seconds, new record 49.49 seconds).
TeamSport invited 130 highly competitive teams to time trials throughout January and February. The 17 fastest went through to an adrenaline-fuelled Championship Final, run over Tower Bridge's amazing two storey, carbon neutral track.
The 520 participants were drawn from financial institutions, insurers, specialist recruitment consultancies and other organisations in and around the Square Mile.
The Morgan Stanley team came in just ahead of a team made up of Bank of America Merrill Lynch employees, with a team representing recruiting firm Montash Associates coming in third.
The City Slicker racers drove new state-of-the-art lithium battery-powered, high octane electric eco-karts, developed specially for TeamSport Tower Bridge. They are so powerful they out-perform the fastest traditional petrol-driven karts, but with none of the emissions. TeamSport Tower Bridge, located less than 10 minutes from the City of London, is a carbon neutral site.
Tower Bridge actually runs two separate tracks which can be joined together for such occasions as the City Slicker Challenge to create one enormous circuit with tricky bends and big drops.
Facilities at the track also include precision electronic timing systems, a large spectator area overlooking pits and track, briefing rooms, and changing areas fully equipped with showers. Drivers and their 'crews' can also refuel in Fuel, TeamSport Tower Bridge's cool track-side bar and kitchen, with its traditional stone baked pizzas, bruschettas, baguettes and more.
Smart conference rooms complete a comprehensive corporate team-building offer. TeamSport Tower Bridge is perfect for work team and group nights out, families, stag and hen parties, or individuals.
