context_page_description: The MG-Lola EX257 is a Le Mans Prototype built by Lola for the MG car company for their attempt to compete again at the 24 Hours of Le Mans in 2001. The car has had many years of mixed success since its introduction, even in privateer hands.
  It was Lola's only car built specifically to LMP675 regulations, and was known by their designation as the Lola B01/60. The last EX257 in original specification was retired from racing in 2007.
context_section_description: The new MG-Lola EX257 made its competition debut at the 2001 24 Hours of Le Mans, with two cars being run by MG Sport & Racing Ltd.  The new cars showed their pace, qualifying 14th and 17th overall, the fastest two times amongst LMP675.  Unfortunately for the race, the problems with the LMP675 formula showed their signs early in the race.  Although quick even with their small engines, these engines were highly stressed and lacked the capabilities to survive long distances.  Following a mere 30 laps, one MG was forced to retire due to exhaust failure.  A few hours later, the second MG succumb to an oil leak, leaving MG retired from the event at a very early stage.
  For 2002, the EX257s were offered to customers for the first time.  Two American teams, KnightHawk Racing and Intersport Racing, would seize the opportunity and purchase one chassis each, for competition throughout the American Le Mans Series season.  Improvements to the EX257 allowed for greater durability, and it was shown at Sebring with Intersport taking the LMP675 win and seventh overall, while KnightHawk took third in LMP675.  Over the rest of the season, the pair of EX257s dominated the series, taking four more wins total.  KnightHawk took the LMP675 championship by a single point over Intersport.  Also, for the final four races of the season, a third EX257 would join the series, in the hands of Dyson Racing, who managed fifth in the championship, even with running a handful of races.
  Back at Le Mans, the factory MG team again returned with their two EX257s.  Their reliability was improved as well, as both cars survived farther than they had the previous year.  Unfortunately gearbox problems eliminated one car after 129 laps.  The second car was running strong until the final few hours of the race, when the engine let go.  The American KnightHawk team also participated, but their car succumbed to fire during the night.
  After two years of being unable to finish at Le Mans, as well as financial strain on the MG Rover Group lead to the sportscar project being cancelled.  However Lola would continue on selling the cars to customers, offering continued technical support along with Advanced Engine Research.  In the American Le Mans Series, KnightHawk Racing would leave, yet its place would be taken by a second Dyson Racing EX257.  Both Dyson and Intersport would trade wins off during the entire season, with the EX257 winning every race that year to give Dyson the championship. Notably, the #16 Dyson entry, piloted by James Weaver and Butch Leitzinger, took an overall victory at the Infineon Raceway round, the first time an LMP675 car had pulled off the upset. However, Intersport made an unusual decision for the final round at Petit Le Mans,  deciding to replace the turbocharged MG engine with a new naturally aspirated Judd KV675 V8.  This move forced the team to make some mechanical changes to their car (now referred to as B01/60), but it was successful as the team managed to take the LMP675 win.  Even with this perfect season for the EX257, Le Mans still saw problems.  A single entry from Intersport failed to finish yet again, due to an engine failure after a mere 102 laps.
  Unfortunately for 2004, the ACO decided to alter the Le Mans Prototype rules due to the inherent problems of the LMP675 class.  The classes were restructured into LMP1 and LMP2, and the MG's found themselves moved into the top LMP1 class.  Over in Europe, Ray Mallock Ltd. would carry on the MG name in the new Le Mans Endurance Series.  The car performed well over the short season, finishing all races and achieved a best finish of fifth, earning them fifth in the teams championship.  In America, Dyson would continue with their two-car squad, while Intersport would continue with their Judd-powered entry.  Unfortunately the success of the previous year could not be repeated, as Dyson was now in the same class as the dominant Audi R8.  Although Dyson was able to score an overall victory against the R8s at Mosport, the team had to settle for second in the championship.  Intersport's hybrid car f
