A test day, Christmas and a month separate rounds three and four of the Formula E Championship, and it is moving from Punta del Este up the River Plate to Buenos Aires, the capital of Argentina. And it is another coastal event out to the east of the city, at Puerto Madero. Initial impressions would suggest that the circuit looks closer to Albert Park than the Sochi-lite in Beijing and the other two Singapore-esque circuits. The pit lane is in a funky layout, which should be irrelevant should the drivers respect the minimum time (Nick). The championship sees a comfortable lead for the man who has appeared on all Formula E podiums, Lucas di Grassi, over the SBs - Sam Bird and Seb Buemi. Di Grassi's Abt has been by far more consistent than his team-mate's version, with Mr. Abt Jr. scoring only two 10th place finishes in the first two, beset by penalties and problems. eDAMS have been quick, with Prost especially rapid in quali trim, and they lead the Teams' Championship from Abt by a squeaky 2 points. All 10 teams have scored points - Dragon are the only team to score points with both drivers in both races, which has helped them beat Andretti's myriad drivers for 4th in the Championship. Venturi are bottom of the Teams' ranking, with the gamble that paid off so spectacularly in Beijing failing conspicuously in Punta del Este, where China Racing's second position is their best result of the season by far. Only Amlin Aguri haven't really had moments of competitiveness. It seems unwise to predict who'll be in the cars in Argentina - Andretti in particular seem keen to run half of France - but we can only hope Formula E continues to win over the doubters with exciting, interesting and changeable racing, even if the speed is unlikely to blow anyone away!
