Isuzu’s midsize SUV takes on a bigger and more powerful form.

There is but a single catch, however. The new model isn’t arriving on our shores as yet, since the D-Max is scheduled to debut first. That means we’ll be having the current Isuzu mu-X for a little while longer. Of course, that’s not stopping us from checking out the areas where the 2021 mu-X has improved over the outgoing version.

Whereas the previous model tops out at 4,825mm long, 1,860mm wide, and 1,840mm high, the 2021 Isuzu mu-X boasts dimensions that are 25mm longer, 10mm wider, and 35mm taller.
