Proton is currently performing on-road tests of the new MPV and is either employing a well known disguise technique of using the body of another similiar vehicle to hide the underpinings of a car being tested, or is currently performing powertrain testing with a body of a similiar weight and size.
If you have a look at the photos, you will see that the interior features the Toyota Wish dashboard, but it has a Proton steering wheel। The interior seems to have a bad fit and finish - weird gaps here and there very atypical of a Toyota. Look at the area around the left-most air conditioning vent as well as the area where the dash meets the center tunnel which runs between the two front seats. The dash could be looking that way because it has been adapted to fit the Proton MPV’s interior. If you look closely, there’s nothing where the dash-mounted shift lever is supposed to be - in this mule’s engine bay is very likely a Proton powertrain and gearbox.
