Jacques Villeneuve has left the Venturi Formula E team after just three races and will be replaced by Briton Mike Conway. The 1997 Formula 1 world champion failed to score a point in any of the opening races and the team said on Twitter there had been a “disagreement over the future direction of the team”. Conway will make his debut in next month’s Buenos Aires round but has previously tested a car for Dragon ahead of the inaugural season in 2014… New two-litre, four-cylinder engines will not be introduced to DTM until 2019. The new engines were the centrepiece of the incoming Class One technical regulations that were due to be introduced for the start of 2017. But Audi, BMW and Mercedes have had concerns about the cost of developing new motors in such a short time so the new rules have now been delayed… The Abt team will switch from running Audis to Bentleys in this year’s Nurburgring 24 Hours. The team will field a pair of workssupported Bentley Continental GT3S in the enduro in May.
