Vector AVTech WX3 The Vector AVTech WX3 is basically the identical twin of the original Vector W8 model. It is built on the same chassis and the construction of the engine is almost exact. The WX3 model never went into mass production, so it remains a concept car. Since the WX3 did not under go the stress test of most cars, the data on it is not fully confirmed. The data presented here on the WX3 is Vector's claim. Under the hood of the WX3 is a aluminum alloy 7.0-liter V-8 engine. This beast pumps out 800+ pound-feet of torque at 4900 rpm. Vector claims that the WX3 has a maximum of 650 horsepower. The chassis of the WX3 is made of a carbon fiber, epoxy composite, nomex honeycomb core. If the claims on the performance of this car are true, and because the WX3 is not in production, we are missing on hell of a car.![]()
