<p>Após o carro turbina da STP perder a Indy 500 para um carro com motor de pistões em 1967, Andy Granatelli sabia que era necessário dar um passo adiante no projeto do carro turbina.  Ele formou sociedade com Colin Chapman que encomendou ao seu designer Maurice Philippe um revolucionário carro, moldado com a comprovada combinação, testada por Andy, de uma turbina industrial Pratt e Whitney com um sistema de tração nas quatro rodas da Ferguson. </p>
<p><!--more--><br />
As Lotus 56 eram considerados os favoritos na Indy 500 de 1968. Quando foi aberta o Speedway em maio, as Lotus foram rápidas desde o início, mas alguns carros com motores V8 turbo também conseguiram acompanhar o ritmo imposto pelos carros turbina. Joe Leonard, Graham Hill e Mike Spence foram desafiados por A.J. Foyt, Mario Andretti, Al and Bobby Unser, Dan Gurney, Lloyd Ruby, Denis Hulme, Mel Kenyon, Roger McCluskey e outros bons pilotos desde o início. </p>
<p><a href="http://grandprixinsider.files.wordpress.com/2008/05/1968-indy-500-spence.jpg"><img class="aligncenter size-full wp-image-1541" src="http://grandprixinsider.wordpress.com/files/2008/05/1968-indy-500-spence.jpg" alt="" width="460" height="200" /></a></p>
<p>Colin Chapman estava ainda abalado com a morte de Jim Clark em abril.. Ele tinha destinado a Clark e Graham Hill os dois pilotos oficias da Lotus na F-1 e Indy. Não visavam apenas à vitória, mas a Indy 500 seria um importante teste para um projeto que Chapman tinha em mente, um conceito de qautro rodas motrices em um carro de F-1.  Mike Spence foi chamado para substituir Clark, enquanto Granatelli entrou com outros 2 carros para pilotos americanos. Infelizmente, em uma sessão de treinos das 500 milhas de Indianápolis, Spence bateu forte no muro externo do circuito e acabou sendo atingido pela roda dianteira da sua Lotus 56.</p>
<p>De luto, Chapman retorna à Europa com o corpo de Spence e deixa os carros turbina da Indy nas mãos de Granatelli. Graham Hill, Joe Leonard e Art Pollard começam a corrida com Leonard na pole. Hill abandona logo no início da corrida, Leonard e Pollard se retiram com problemas na bomba de combustível. Leonard estava liderando a corrida e a poucas voltas do fim seu motor turbo morreu. Granatelli não obteve muito sucesso e no final da temporada os carros inovadores se tornam obsoletos quando o órgão esportivo (USAC) proíbe os motores turbina e tração 4x 4 tempos.</p>
<p><a href="http://grandprixinsider.files.wordpress.com/2008/05/1971-walker-lotus_56b.jpg"><img class="aligncenter size-full wp-image-1542" src="http://grandprixinsider.wordpress.com/files/2008/05/1971-walker-lotus_56b.jpg" alt="" width="460" height="191" /></a></p>
<p>Chapman continuou desenvolvendo o 56, pois acreditava no potencial do carro como arma no mundial de F1. Principalmente porque o modelo 63, que aliava a tração nas quatro rodas com o motor Ford Cosworth convencional foi um fracasso. Mas esmo que no papel parecendo promissor, não tinha como negar que o carro era muito pesado e um tanto complicado para a época. Em 1971 Emerson Fittipaldi correu com o novo 56B em corridas extra-campeonato como o Race of Champions e o International Trophy. Durante os treinos na pista encharcada de Brands Hatch, o 56 eera de longe o carro mais veloz do grid. Mas como a corrida aconteceu no seco, as vantagens sumiram e o brasileiro só andava no pelotão mediano.</p>
<p>Em Silverstone, no International Trophy, o carro só durou três voltas até a suspensão quebrar. Chapman então decidiu aproveitar uma etapa do campeonato da Formula 5000 em Hockenheim na Alemanha, para testar o 56B antes do GP da Itália. Foi nesta ocasião que eu, moleque de 11 anos, tive o prazer de conhecer o Emerson pessoalmente. Ele terminou em segundo em ambas a baterias atrás do australiano Frank Gardner, que pilotava um Lola T330 de fábrica. Pouco depois terminou em oitavo lugar em Monza. </p>

<p>Mas Chapman viu que tinha obstáculos demais a superar para tornar o carro turbina em um vencedor e acabou abandonando o projeto do 56B, deixou a tração nas quatro de lado e também descartou turbinas de seus futuros planos. Em vez disto optou em continuar desenvolvendo o modelo 72, na sua criação inspirado pelo design do 56 original, e que conquistaria nas mãos de Emerson mais um titulo em 1972, além do Mundial de Construtores.</p>

<p>After the STP turbine car had lost the Indy 500 to a piston engine car in 1967, Andy Granatelli knew he needed to take a further step with the turbine car project. He teamed up with Colin Chapman and the Brit had his designer Maurice Philippe develop a revolutionary wedge shaped car around Andy's proven combination of a Pratt and Whitney industrial turbine engine with a Ferguson four wheel drive system.</p>
<p><!--more--><br />
The Lotus 56 looked to be a major contender for the 1968 Indy 500. When the Speedway opened in May, the Lotusses were fast right from the start, but several piston engine cars kept pace with quick speeds as well. Joe Leonard, Graham Hill and Mike Spence were challenging A.J. Foyt, Mario Andretti, Al and Bobby Unser, Dan Gurney, Lloyd Ruby, Denis Hulme, Mel Kenyon, Roger McCluskey and other top drivers with their conventional piston engined cars from the outset.</p>
<p><a href="http://grandprixinsider.files.wordpress.com/2008/05/1968-indy-500-spence.jpg"><img class="aligncenter size-full wp-image-1541" src="http://grandprixinsider.wordpress.com/files/2008/05/1968-indy-500-spence.jpg" alt="" width="460" height="200" /></a></p>
<p>Colin Chapman was still downbeat after Jim Clark's death in April, he had originally intended to enter the two Lotus Formula 1 drivers, Jim Clark and Graham Hill. Not only would they aim for victory, but the Indy 500 would also be a significant test drive for a similar concept of a four wheel drive Formula 1 car Chapman had in mind. So he had Mike Spence replacing Clark, while Granatelli himself would enter another two cars for American drivers, including Parnelli Jones. Unfortunately Spence would hit the outer wall and would be struck by the front wheel off his Lotus 56 in one of the Indy 500 test sessions.</p>
<p>A grief stricken Chapman returned to Europe with Spence's body and left the turbine Indy cars in Granatelli's hands. Eventually Graham Hill, Joe Leonard and Art Pollard entered the race with Leonard on pole. Hill crashed out early in the race, and Leonard and Pollard both retired with fuel pump problems. Leonard was in the lead with just a few laps to go, when his turbine engine died. Granatelli campaigned the cars with little success and the end of the season the innovative cars were left obsolete when the sport's governing body (USAC) banned both turbine engines and four wheel drive.</p>
<p><a href="http://grandprixinsider.files.wordpress.com/2008/05/1971-walker-lotus_56b.jpg"><img class="aligncenter size-full wp-image-1542" src="http://grandprixinsider.wordpress.com/files/2008/05/1971-walker-lotus_56b.jpg" alt="" width="460" height="191" /></a></p>
<p>Chapman developed the 56 as a potential F1 machine after the failure of the four wheel drive Lotus 63, but while the car was promising, it was too heavy and too overcomplicated for F1. Emerson Fittipaldi tried the car in the 1971 Race of Champions and International Trophy non-Championship meetings. At Brands Hatch, during wet practice, the 56 was far and away the fastest car on the track, but the race was held in dry weather and the car was lost in midfield.</p>
<p>At the Silverstone-based International Trophy, the car only lasted three laps of the first heat before suspension failure forced Fittipaldi's retirement. Fittipaldi then competed in a round of the Formula 5000 championship in Hockenheim, Germany, as a test race for the upcoming Italian Grand Prix. That was the opportunity when I met Emerson personally fro the first time. He came home second in both heats behind a dominant Frank Gardner. At the high speed Monza track he managed to bring the car home in 8th.</p>
<p><a href="http://grandprixinsider.files.wordpress.com/2008/05/1971-fittipaldi-lotus-565b-monza.jpg"><img class="aligncenter size-full wp-image-1543" src="http://grandprixinsider.wordpress.com/files/2008/05/1971-fittipaldi-lotus-565b-monza.jpg" alt="" width="460" height="191" /></a></p>
<p>By then Chapman decided to cut his losses and abandoned the 56, the four wheel drive concept and the gas turbine engine to concentrate on the Lotus 72, which had been inspired in the 56's wedge design, and would secure another drivers' and constructors' championships for Lotus in 1972.</p>
