BMW has just been caught testing the upcoming BMW 1 Series with the new M package. This is the first time we've seen the new model wearing M enhancements.

It appears to feature the usual M upgrades, including sporty alloy wheels (although they might be silver on the production model), a subtle bodykit with more aggressive front and rear bumper bars, and lowered sports suspension.

The new 1 Series itself will feature the same design language as the latest generation of BMWs, including a pronounced nose and headlight layout similar to the new 5 and 7 Series, and a pointier creased bonnet line.

The cabin of the new model also appears to feature a larger rear section, giving it a fuller look than the existing range. This might bring more cargo space and increased rear-seat headroom.

Reports say the 2012 BMW 1 Series will be available with a new 1.4-litre PSA Peugeot engine, as well as a new 2.0-litre turbocharged unit. Diesel options will also be offered.

The 2012 BMW 1 Series is expected to debut sometime towards the end of this year.
