Land Rover is preparing a slight freshening of the its seven-passenger, mid-range LR4 (known outside of North America as the Discovery 4). The LR4/Disco 4 is currently the second oldest model in the Land Rover range, besides the mostly forgotten LR2/Freelander, and while it's still a competent entry, its age is beginning to show.

This refresh should allow it to soldier on until a replacement can be built, which logic would dictate is to be called LR5/Discovery 5. Until then, the current SUV gets the typical batch of headlight tweaks, along with a freshened front bumper. The side mirrors are new as well.

On the inside, we can also expect a long-awaited upgrade to the infotainment system. Jaguar and Land Rover have both struggled in this regard, so here's hoping the new system offers an improvement.

The big news for the LR4 will come under its hood. Jaguar Land Rover as a whole has already phased out the excellent but thirsty 5.0-liter V8, with the only holdover being the supercharged variant. That means the V8 LR4 is not long for this world. Look for it to be replaced by the same supercharged, 3.0-liter V6 that's offered as a base engine in the Range Rover and Range Rover Sport. As with the Jaguar XF we tested, ZF's eight-speed automatic would likely harness the V6's power.

Expect to see a refreshed LR4, likely before the end of 2013.
