<strong>Bitter</strong> <strong>GT1</strong><br />
Technical Specifications (<strong>1998</strong>)<br />
<strong>Bitter</strong> <strong>GT1</strong> FIA <strong>GT1</strong>-car<br />
The history of this car goes back to 1997 when<br />
Dutch entrant Toine Hezemans entered a pair of<br />
Lotus Elise <strong>GT1</strong> cars in the FIA GT<br />
Championship. They had Lotus/Chevrolet V8<br />
power. Lack of success and the appearance of<br />
more developed designs meant that Lotus<br />
shelved their <strong>GT1</strong> project. For <strong>1998</strong> Hezemans<br />
reworked his Lotus Elise based <strong>GT1</strong> cars and<br />
installed Chrysler Viper V10 engines into the<br />
Lotus chassis instead of the V8 powerplants. A<br />
new body was designed. To be able to run his<br />
GT special in proper FIA recognized series<br />
Hezemans needed his car to get homologation.<br />
Hezemans not beeing recognized as a<br />
constructor, he sought contact with <strong>Bitter</strong>, a<br />
German producer of limited-production GTcars.<br />
They struck a deal to name the Hezeman<br />
special as <strong>Bitter</strong> <strong>GT1</strong>'s. Apart from that there<br />
were no other involvement of <strong>Bitter</strong>. The car<br />
proved to be unsuccessful and it was shelved<br />
after only a few outings.<br />

HISTORY - BITTER <strong>GT1</strong> by Rainer Nyberg<br />
The history of this car goes back to 1997 when Dutch entrant Toine Hezemans entered a pair of Lotus Elise<br />
<strong>GT1</strong> cars in the FIA GT Championship. They had Lotus/Chevrolet V8 power. Lack of success and the<br />
appearance of more developed designs meant that Lotus shelved their <strong>GT1</strong> project. For <strong>1998</strong> Hezemans<br />
reworked his Lotus Elise based <strong>GT1</strong> cars and installed Chrysler Viper V10 engines into the Lotus chassis<br />
instead of the V8 powerplants. A new body was designed. To be able to run his GT special in proper FIA<br />
recognized series Hezemans needed his car to get homologation. Hezemans not beeing recognized as a<br />
constructor, he sought contact with <strong>Bitter</strong>, a German producer of limited-production GT-cars. They struck a<br />
deal to name the Hezeman special as <strong>Bitter</strong> <strong>GT1</strong>'s. Apart from that there were no other involvement of<br />
<strong>Bitter</strong>. Despite the Chrysler V10 power the car proved to be unsuccessful and it was shelved after only a few<br />
outings. Lack of funds meant that it was never developed properly. It was not seen again.<br />
