Press Release) 23 August 2006 - Today the record-breaking
JCB DIESELMAX achieved a stunning 350mph (563kph)* to break its own
land speed record for diesel-powered cars set yesterday by Andy
On Tuesday, JCB DIESELMAX became the world’s fastest diesel when
Green drove it to an FIA-sanctioned speed of 328.767mph
(526.027kph). Today he improved on that significantly with a new
record of 350.092mph (563.418kph) after two passes in opposite
directions, within one hour.
Running soon after daybreak he recorded 365.779mph (588.664kph) on
his first run and 335.695mph (540.248kph) on his return, giving the
average of 350.092mph (563.418kph).
As he was feted by his jubilant crew, Green said: “I am so pleased
that we have got the car to 350mph which was always our ultimate
goal and that was with a slow start to the second run. There is so
much more to come as the car is pulling like a train and we still
haven’t used sixth gear!
“Today’s record proves the potential we have always believed JCB
DIESELMAX to possess. This is another great result for a wonderful
team and a testament to British engineering.”
"350mph is a fantastic speed for a diesel-powered car. To have built
the world's fastest diesel in such a short timescale is a wonderful
achievement for the JCB DIESELMAX team,” said Dr Tim Leverton,
Project Director. “What is even more impressive is to set three
records – 317.021mph, 328.767mph (526.027 kph) and 350.092mph
(563.418kph) in only six days.
"Once again we have demonstrated the engineering and team effort
that has gone into creating this extraordinary car.”
JCB DIESELMAX was JCB Chairman Sir Anthony Bamford's brainchild,
born of his desire to showcase the extreme performance of the JCB444
diesel engine which normally powers the company's backhoe loaders
and Loadall telescopic handlers.
After watching today’s runs he said: “Yesterday’s triumph was
thrilling, and better than I had expected. Today’s surpasses even
that. We have proved that we can do it, and we have the world’s
fastest diesel car and engine. The JCB DIESELMAX team has worked at
times in adversity and faced numerous heartaches with fortitude.
These record-breaking successes prove to the world the excellence of
British engineering and teamwork.”
JCB, one of the world’s
leading construction equipment companies, will make a land speed
record attempt this summer in a bid to earn its purpose-designed
streamliner car the title of “World’s fastest diesel”. To reach
speeds of over 300 mph, JCB has developed the world’s most powerful
automotive diesel engine at 150 bhp per litre.
The attempt at a new land speed record for diesel cars will
underscore the strength, performance and versatility of the JCB444
diesel engine. The JCB DIESELMAX car is twice as powerful and twice
as fast as a Formula 1 car, yet weighs four times as much.
The aim is to create the world’s fastest diesel-powered automobile
and set a new record in excess of 300 mph. The current FIA mark
stands at 235.756 mph to Virgil W Snyder and the Thermo King
Streamliner, a record that dates back to 25 August 1973.
The JCB DIESELMAX streamliner will be driven by Wing Commander Andy
Green, who set the first-ever supersonic world land speed record at
763.035 mph in ThrustSSC on the Black Rock Desert on 15 October
The innovative car has been designed by a team led by JCB Group
Engineering Director Dr Tim Leverton. Richard Noble, the former land
speed record-holder, has acted as a consultant to the project, and
JCB has worked with long-term technology partner Ricardo plc to
develop the JCB444-LSR engine.
Codenamed project H1, JCB DIESELMAX is nine metres long, weighs 2700
kg and is powered by two 750 bhp two-stage turbocharged JCB444
diesel engines driving through separate six-speed transmissions.
The record attempt will take place on the Bonneville Salt Flats in
Utah in August, following preliminary trials at RAF Wittering, near
Sir Anthony Bamford, Chairman of privately owned JCB, is very clear
why he wanted to build a JCB record-breaker: “I am passionate about
the importance of engineering excellence to Britain and I see using
the JCB engine for this record attempt as a fantastic way of
showcasing what British engineers can do.”
Dr Leverton said: “We began this project with one basic aim.
Everything always comes back to that same starting point; we are
doing this to prove our engine. To power the world’s fastest diesel
car with two JCB engines designed for our construction machines will
be a huge achievement.”
Andy Green said: “We will be following in the tradition of Sir
Malcolm Campbell, George Eyston and John Cobb, three of the greats
of record-breaking. And we will be running at the sport’s spiritual
home, the remarkable Bonneville Salt Flats.
“I am really looking forward to driving another British entry in the
‘300 mph Club’, and a diesel-engined, wheel-driven one at that.”
