This weekend see's all 3 major single seater series running races. F1 is running it's 1000th race in China, Indy car is at Long Beach and the streets of Rome will be alive with the sound of electric cars with the second running of the Rome E-Prix. Last year's race was a bit of a thriller with lots of wheel banging and the eventual winner being Sam Bird. It's a victory he could really do with reordering after the DNF last time out. Also running near the front last year were Mahindra, Teechetah and Renault. Renault are now of course Nissan who have the in form Oli Rowland leading the way for them this year. Rowland has looked good without actually getting great resultas of yet but seems to be getting the best of Sebastian Buemi and second last time out is a good starting point. Jean-Eric Vergne won last time out and that has catapulted him into championship contention again but the real ones to watch are Audi who always seem to come good as we get into the European season. Having said that Lucas Di Grassi threw a wobbley after being taken out in the last race and really is only at his best when he is calm so will be interesting to see which Lucas turns up. Every Formula E weekend I mention that D'ambrosio is up the top but not really considered a contender. He keeps getting results though so maybe we should start to think of him as such. Certainly Mahindra were best on the Rome track last year and only lost victory when Rosenqvist put it in the wall. A couple of driver changes elsewhere with Piquet Jr having left the series with the Jaguars in a downward spiral. He has been replaced by Alex Lynn who will be looking for redemption after a frankly awful season with Virgin last year. Also taking a break for one race is Felipe Nasr who has been completely anon anyways - Gunther is back in for the race. Once again this race could really go anywhere and to anyone with BMW looking back on song and Mortara in the Venturi also looking very racey now days. Coverage as always will be on BBC iPlayer, Eurosport and BT sport. All that and a live stream on the website. All races this year have been top notch so far so very much looking forward to this as usual.
