The next generation Porsche 911 will be a significant departure from all previous generations, though to the untrained eye that could be a hot-air boast. The chief novelty of the 991, confirmed for us recently by Porsche sources in Germany, is that the entire range will benefit from a KERS device, such as what was used by a couple of teams in Formula 1 in 2009 and then immediately banned by the FIA for the 2010 season as an unfair advantage, only to be allowed again for this 2011 season.
