Dynamic 4 was the N/A model in europe. They also had a weaker transmission and no rear VCU and weak 3-bolt axles compared to the VR4. Also no leather Interior was available, but i think only VR4 for US and some RHD variants for japan and australia came with leather interior.
There were also 4WD variants with 4G63 SOHC and even 4G37 1.8l engines available which were sold as "Dynamic 4" in some countries (AFAIK also without 4WS). They often also had the small/metal front&rear bumpers or sometimes the GTI bumpers which are smaller than the dynamic4 ones (vr4 had the extra vents at the splitter) and no side skirts.
At least in Germany only those with all 4 systems (4WD, 4WS, 4IS and 4ABS) were labeled Dynamic4 - hence the *4* - and they all had the larger vr4-like bumpers and side skirts. The only options left (besides seperately sold accessories) as far as i know were the sunroof and air conditioning. Otherwise they already had everything else included, thats why it was quite expensive at 45.000,- DM and not even 500 units were sold in germany...
Even the Starion was cheaper and until the Sigma and 3000GT arrived in 1991 the Dynamic 4 was the most expensive model from Mitsubishi available in germany. (Although the Pajero could be made more expensive with enough options added...)
