Seen for the first time at the Geneva motor show, the new models feature a sporty design with black aluminium wheels, tinted rear windows and new black exterior trim.
Inside, the new models get red stitching on the steering wheel, black interior trim and sports seats.
The additions bring Skoda's Monte Carlo selection of vehicles to five, with the current Fabia and Fabia estate already part of the range.
The Monte Carlo special editions celebrate Skoda's motorsport achievements, including its success at the Monte Carlo Rally. The Czech manufacturer won the European Rally Championship, Asia-Pacific Rally and South American Rally Championship in 2013.
Although not coming to the UK, the Octavia G-TEC offers a range of 826 miles and is powered by a 1.4-litre TSI turbocharged petrol engine with 108bhp.
