Lotus Soapbox Racers Sold


News has reached us that the Lotus 119 Series soapbox racers have been sold.


News has reached us that the Lotus 119 Series soapbox racers have been sold.

The racers were built to race at the Goodwood Festival of Speed, and the fully enclosed 119C was never beaten. After the Goodwood FoS ended their soapbox racing in 2004, the 119 series were retired and used predominantly for display, although they were occasionally wheeled out to appear on TV.

It is understood that a deal has been done to sell all three of the racers to the Barber Vintage Motorsports Museum in Alabama, so it seems that these iconic British soapbox racers will never be seen in the UK or on a race track again.

Soapbox World Speed Record Set by Guy Martin

Guy Martin Gravity Racer

Guy Martin has set the world record for the highest speed set by a gravity racer.

Using a racer designed by Sheffield Hallam University, he achieved and average speed over a measured 100m of 85.612mph (137.779kph) with a racer weighing 200Kg at Mont Ventoux.

The benchmark has been set. To set the world record, you need to beat 85.6mph over 100m with a racer that is 200Kg or less. 

There will doubtless be many attempts at this over the coming months, and it seems that Guy's record is unlikely to stand for long, but that doesn't take anything away from the skill of the team that achieved this tremendous speed. Congratulations to all involved.

For more information about the work that went in to the record attempt, see the Engineering Sport web site.
