REPORT CONTINUED Bernard Bussy (management) and Daniel Aquilon (engineering) in the showroom. Just like in the full-sized version, the light-alloy pistons of the miniaturized Testarossa engine have three cylinder rings: two compression rings and one oil ring. “ Building engines is pure passion. There’s not a trace of a business idea behind it. ” Bernard Bussy With the simplest of tools – a drill press, a cross table with a milling cutter and a small lathe, Daniel continues to produce perfectly functioning miniatures to this day. Among his creations are a Stirling engine, several one- to 12-cylinder four-stroke engines in boxer, inline and V configurations, a one-cylinder diesel and even a 14-cylinder radial engine. ENGINEER MEETS COMMUNICATOR Daniel Aquilon and Bernard Bussy met by chance in 2002. Daniel was just working on his first twelve- cylinder engine at the time, the legendary Ferrari® 60° V12 designed by Gioacchino Colombo, with one overhead camshaft for each cylinder bank, three carburetors, a two-valve design and wet oil sump. Bernard, who already had a high concentration of gasoline in his veins, promptly fell under the spell of the V12’s throaty howl. What resulted was the idea of making these masterpieces of engine construction accessible to a wider audience under the name Motorconcept. FIRST TWELVE-CYLINDER AT AGE 60 Almost on the day of his 60th birthday Daniel finished his first twelve-cylinder engine. It was a sensation! But he had reckoned without Bernard, who already had an even bigger challenge in mind for his “teammate”: the 180° V12 designed by Mauro Forghieri, first used in a Formula 1 Ferrari® 512 F1 (1964–65). In a 16

Daniel takes the measure of a “grown-up” Ferrari ® 512 TR. “The Colombo-V12’s pièce de résistance: the crankshaft.” Daniel Aquilon number of variants, this engine would go on to power thousands of produced 365 GT/4 BB, BB 512, BB 512i, Testarossa, 512 TR and 512 M cars between 1973 and 1996. If the crankshaft was the “pièce de résistance” and most difficult part of the Colombo-V12, in the new 12-cylinder it would be the four-valve cylinder heads controlled by a timing belt and the electronic fuel injection system. Like its big original, the 512-TR engine also features dry sump lubrication. Putting in over 4,000 hours of work, Daniel completed the unique piece in just two years. Miniature crankshaft (actual size). PRECISE TO THE LAST DETAIL It’s worth noting that not everything can simply be reduced to a 1:3 scale. For example, making the spark plugs – which of course Daniel also builds himself – too much smaller would leave too small a gap between the center and ground electrodes.
