From the listing for this 1970s Lotus F1 car for sale:
Lotus 78 F1 with Ford Cosworth DFV. The iconic Lotus 78 was driven by Mario Andretti, Gunnar Nilsson and Ronnie Peterson during the 1977 and 1978 seasons. It was the car that started the ground effect revolution as Colin Chapman was the first to use the inverted wing philosophy – and to great effect, with Andretti winning 4 times and Nilsson winning the Belgian GP, and Andretti only missing the World Championship because of engine failure in 1977 before using the 78 in the first part of the 1978 season – winning in Argentina and Peterson winning in South Africa before the equally dominant 79 was introduced which helped Andretti become world Champion in 1978.
In 2009 the car was restored by Classic Team Lotus and the car has been part of a significant collection for the last few years. The engine was rebuilt at the same time and has only been used for demonstration purposes. Offered for sale with new crack test, fuel cell and current FIA HTP papers, as well as 2 set of spare wheels, this is an iconic an emotive Lotus F1 Car and would fit seamlessly into a serious collection.
The 78 was loosely based on the Lotus 72, sharing the same basic wedge shape and internal layout, but featuring detailed aerodynamic improvements, better weight distribution and a longer wheelbase. It had a slimmer, stronger monocoque made from aluminium sheet and honeycomb, which was developed from the 77. The bodywork was made up of fibreglass body panels with aluminium used to strengthen the chassis at points. The car created quite a stir when it first appeared, and outwardly seemed ahead of its time. Internally of course, it was a quantum leap ahead. Andretti worked hard with the car, testing for many thousands of miles at the Lotus test track in Hethel.
Based on Bernoulli’s discoveries, the underside of the sidepods were shaped as inverted aerofoils, in the same vein as conventional wings but on a much larger scale. Wright and Chapman had discovered that by shaping the floor of the car in this way, they could accelerate the air passing through the gap between the ground and the underside, thereby reducing the air pressure under the car relative to that over it. This created a partial vacuum, effectively sucking the vehicle down which forced the tyres harder onto the track.
