Lotus
Esprit X180R
Type
105
The
Lotus Esprit competed in the 1990 American SCCA, Sports Car Club
of America Escort World Challenge, a series for modified production
cars. Lotus had needed a race program to promote the Esprit in the
US market, so Lotus produced the Type 105 Esprit SE SCCA. Externally,
the car featured perspex windows with a rear wing and front splitter.
The Esprit SE SCCA was an upgraded and race prepared SE.
The car featured
AP Racing disc brakes, revised suspension geometery and a new engine
management system. The car produced 285 horsepower (with the aid
of the Lotus Carlton fuel injectors) from the Lotus Esprit SE 910S
engine. Lotus also made 20 road going versions of the Type 105,
also called the Lotus Esprit X180R. They had 2 sports seats, air
conditioning and a galvanisation chassis, which wasn't available
on the SE SCCA race car. Driven by Doc Bundy and Scott Lagasse,
the results were impressive, with 4 victories in 8 races, including
2 1-2 placings, 6 pole positions and a total of 2,900 miles with
no mechanical breakdowns. The 105 also set the fastest lap in 6
of the 8 races.
Type
106
In 1991, LotusSport Inc. made 3 Lotus Esprit X180R cars, to enter
the SCCA. These were modified from the 1990 spec SE and given a
Type 106 designation. The 1991 X180R had larger alloys, and a strengthened
chassis with a revised FIA approved roll cage, which helped give
the car bettter torsional rigidity. The car also had larger fuel
injectors, improved charge cooling and a non catalytic exhaust system,
which helped to increase power to 300bhp. The car was sucessesful
in the SCCA in 1992, with Doc Bundy winning the title. In 1993,
the IMSA, the ruling body of the SCCA, change the rules to favour
other manufacturers, as Lotus was clearly too successful in the
championship. Points would be awarded to pole position and second
on pole. Although the Lotus Esprit was nimble, it had 100bhp to
200bhp less than other manufacturers and couldn't get on pole. So
for the 1993 season, the success was over.
The
X180R was driven by Doc Bundy, Andy Pilgrim, David Murry, Bo Lemler,
Steve Hansen, Scott Lagasse, Paul Newman (the Film Star), Mike Brockman,
Duncan Drye and Peter Shea.
