While the Italian car maker known as Maserati has just made a re-entry into the Indian market, at the recently concluded Frankfurt Motor Show, the car maker has shown off its updated Ghibli and Quattroporte. Their performance specifications remain unchanged but the new engines are up to 12% more fuel-efficient than their predecessors. Diesel variants aren’t left out either as they have been equipped with AdBlue technology. Despite this, the company says performance, emissions and fuel-economy numbers remain unchanged. However the new engines use start-stop technology. The cars also get new safety technology like Blind Spot Alert and Siri Smart personal Assist. There are also additional features such as new Harman Kardon system as a standard feature and a wide list of personalization options.
