in mosport, its first offical race, the brand new Jaguar AJv8 engine was a great hit. claiming pole positioning, and was in 1st from flag to flag. It beated two ford-power xkr as well. and as previous stated. jaguar is considering producing a limited number of 4.5L engines. not as powerful as the racing 650 hp. but strong enough to make the m5 5.0 look weak in comparison.
