Jaguar AJ-V8 Engine - AJ26

The 4.0 L (3996 cc) AJ26 engine was introduced in 1996. The number "26" comes from 12+6+8 (cylinders), because when the first ideas were sketched nobody knew whether the outcome would be a 12, a 6 or an 8 cylinder block. Of course it became 8, focused on the North American markets. It has a square 86 mm (3.4 in) bore and stroke. It was updated in 1998 as the AJ27 with continuously variable valve timing. The AJ-V8 was updated again in 2000 as the AJ28. The naturally aspirated version produces 290 hp (216 kW) in the 2004 XK8.
