there is also this one, which has a volvo patented port water injection system, AND traction control in 1983-84. the water injection uses normal fuel injector/pump/etc and a special water/lubricant to have port style water. i guess the benefit is very low water consumption. they were running 20-23psi on the 2.1 liter volvo engines for 350-370hp.
the traction control is the first ever, it consists of magnets on the #2 and 3 CIS injectors, so it can cut fuel.
