The BMW 1-Series was introduced three years ago so it comes as little surprise that the company is working on a minor facelift for their entry-level hatchback.

The BMW 1-Series was introduced three years ago so it comes as little surprise that the company is working on a minor facelift for their entry-level hatchback.

This particular prototype is the new M135i and it appears to feature a new front bumper, a revised grille and smaller headlights. The styling changes are less notable out back but the camouflage suggests there will be a new rear bumper.

Engine options will likely include the usual suspects, so expect the M135i to feature a 3.0-liter TwinPower Turbo inline-six that cranks out 326 HP (240 kW) and 450 Nm (322 lb-ft) of torque.

The 1-Series facelift could be introduced later this year or early next year, so expect to learn more in the coming months.
