The seventh round of the 2013 FIA WTCC takes place in Portugal this weekend at the 4.9km 'Circuito da Boavista' in the heart of the country's second largest city, Porto.

This is the second street circuit that the series visits this year and like other city street circuits such as Marrakech and Macau, it has a reputation for being, fast, tight, twisty, tough and technical.

Any mistake is usually punished by a trip into the barriers.

The twelve corner track has a mixture of twisty and narrow corners and nearly a long back straight of nearly a kilometre in length. This means car set-up is vital; a balance of aerodynamics and car agility should help towards a good base setting for the track.

The 'Race of Portugal' has alternated in the past between three circuits; Porto, Portimao and the former F1 track, Estoril which made an appearance in 2008. 2013 will be the fourth time that the touring cars will visit Porto.

* This is one of championship leader, Yvan Muller's, 'bogey' circuits, having failed to win a race in previous visits. However, having a 113 point lead in the championship over Gabriele Tarquini means that Muller can afford to go all out for his first Porto win.

* Alain Menu is actually the most successful driver at the track - taking two victories in previous attempts and also holding the pole position lap record of 2:04.946 in his RML Chevrolet.

* Tarquini, Rob Huff, Andy Priaulx and Augusto Farfus have all taken a single race win each. Huff is the current race lap record holder with 2:05.846 from his race two victory in 2011.

* Home town hero, Tiago Monteiro, will be looking for a strong result in front of his adoring fans. The Castrol JAS Honda Racing driver has taken a single podium at Porto during race one in 2011.

* Chevrolet are the most successful manufacturer having won three times at this track, with BMW taking two victories and a single win for SEAT.
