APX is manufactured predominantly from aluminium in the form of high-pressure
die-cast corner nodes, stampings and extrusions. It uses advanced assembly techniques,
including adhesive bonding, self-piercing rivets and flow-drill screws for construction -
joining techniques that Lotus calls Riv-Bonding.
Lotus has optimised the use of these
technologies thus significantly reducing the number of mechanical fixings within the
monocoque structure. This has reduced the level of investment required in manufacturing
APX is not just a Lotus Engineering concept, but a feasible prototype close to production;
it is not a concept indicating a strategic direction of Lotus Cars; it is, however, a
brilliant demonstration of VVA and the skills of the team from Lotus Engineering into what
is regarded as the future of niche vehicle manufacture. APX is production feasible as all
the components can be made cost effectively and in high niche volume (up to around 30,000
APX is powered by a V6 engine has been designed by Lotus Engineering's powertrain division.
The directive for Project NEF was to produce a high performance prototype engine without the
need to resort to exotic materials or manufacturing technology, allowing manufacture around the
APX's engine is a supercharged 3 litre (2996 cc, Bore: 88 mm, stroke: 82.1mm) V6 DOHC engine,
mounted longitudinally in the front of the vehicle.
