Audi’s motorsport-inspired, fivecylinder turbo creation has continued its amazing, trophy-laden run at the International Engine of the Year Awards. The 2.5-litre unit out of Ingolstadt, known for its sporting performance and its fiery character, has taken top honours in the grouping since 2010.
But for 2018, the Audi heart still had to work hard to earn its title as this year’s winner, fighting off some serious competition from VW Group sibling Porsche with its 2.5 fourcylinder turbo, which drives the 718 Boxster S and the 718 Cayman S racers. However, the five-pot held its nerve to snatch the crown for the ninth time, amassing an impressive 470 points – rolling home 118 points clear of Porsche’s entry and 296 points ahead of Ford’s 2.3-litre turbo in the brilliant Focus RS. Additional competition in this grouping included Mercedes-Benz’s workhorse 2.1 fourpot diesel, Toyota/Lexus’s smooth 2.4 hybrid powertrain and Subaru’s 2.5 turbo WRX STi heart.
Oozing engineering greatness, it’s not difficult to discern why the powerplant has remained a firm favourite with the Awards jury. Its fizzling, crackling soundtrack is one of the most spirited on the market, powerfully evocative of the Quattro’s 1980s rally heyday. Housed in the TT RS, the firecracker develops 405ps and 480Nm torque, accelerating the car from zero to 100km/h (62mph) in 3.7 seconds and on to a top speed of 250km/h (155mph).
Such has been its continual impact that the judges can’t help heap yet more praise on the now legendary engine. “Audi’s warbling five-cylinder turbo motor is a potent, charismatic powerplant that evokes memories of the Ur-Quattro,” enthused freelance journalist Gautam Sharma, one of 17 new judges on the IEOTYA jury.
Meanwhile, Halit Bolkan, editor-in-chief of Turkish outlet Otohaber Magazine, said, “It’s really a masterpiece of engineering. The engine’s exceptional sound and performance are unique.”
