side-valve engine although the latter was still common at this time. An overhead valve version came later. During the Second World War he secretly worked with his design team at his works at Asnières-sur-Seine on a small car the Aluminium "Francais-Grégoire". It had a chassis-body frame of light alloy, front-wheel drive, an air-cooled flat twin engine and independent suspension on all wheels. A four-seat car weighing only 880 pounds (400 kg) and could reach 60 mph (97 km/h) while returning 70 mpg^[vague]. This design was to form the basis of the 1950 "Dyna" Panhard. In 1950 another Hotchkiss car the Hotchkiss Grégoire, was produced again with an alloy chassis and body. With independent suspension on all four wheels and fitted with a water-cooled flat four engine of 2 litres, ahead of the front axle, it was fast, with a top speed of 94 mph (151 km/h), but the car was expensive and only 250 examples were made by 1954. In 1956 Grégoire produced a two-seat convertible with a 2.2-litre supercharged flat-four engine producing 130 PS (96 kW; 128 hp) and, as in the case of the cars mentioned previously, front-wheel drive. All ten cars made were fitted with bodies designed and built by Henri Chapron
