Fiat will unveil its latest Panda at the 2011 Frankfurt auto show in mid-September and warns that all-wheel drive is on the way.The automaker describes the car, due for showrooms early in 2011, as "a consistent evolution of a highly successful city car that has always been a byword for functional design, manoeuvrability, space, reliability and comfort".FIVE TO GO"While still remaining true to its compact design brief," Fiat adds, "the new Panda has ‘grown’ by just a few centimetres to ensure the attainment of the highest safety standards and improve the generous level of passenger and luggage space."With an overall length of 3.65cm, width of 1.64m and height of 1.55m, this Panda can comfortably accommodate up to five people and is equipped with one of the largest boots in its segment."The Panda has a number of "firsts" in its history: it was the first in its segment to have a diesel engine (1986) and it was the first to offer allwheel drive (1983) and a range of eco-friendly engines designed to limit fuel consumption. (Panda Elettra, in 1990, was one of the first battery cars)."This the third-generation Panda has taken another major step forward," Fiat says, "in terms of comfort, technology and crash protection and has a modern and harmonious new style without relinquishing the essential family feeling that has so characterised the car over the years."NEW ENGINESThe car has a softer, rounded shape and, Fiat says, quality and reliability have been optimised.A new engine range includes two TwinAir twin-cylinder engines: the International Engine of the Year 2011 65W TwinAir Turbo or the brand new non-turbo 49kW TwinAir, each with stop/start.The recently revised four-cylinder,, 52kW 1.2 Fire engine completes the petrol engine range at launch but a 56kW turbodiesel 1.3 MultiJet 2 engine, also with stop/start, will be offered later - along with all-wheel drive.
