The five-cylinder engines from Audi have achieved cult standing – partly due to their successful deployment in motorsport and also on comment of their trustworthiness and economy. The engine’s singular 1-2-4-5-3 ignition method and a exquisite sound that comes with it make a pushing knowledge so exhilarating.
The initial five-cylinder gasoline engine powered a Audi 100 (C2) in 1976. The model, famous internally as Type 43, was to be positioned aloft than a prototype in a market. The four-cylinder engines during a time were not suitable for this devise according to a developers. At a commencement of a 1970s, Audi engineers hence discussed a probability of introducing 5 and six-cylinder inline engines. The latter were ruled out due to a designation space compulsory and adverse weight distribution. So those obliged opted for a five-cylinder inline engine, shaped on a new EA 827 engine concept. This four-cylinder inline engine was used via a VW Group in a 1970s – in a Audi 80 and Audi 100, for instance. The subsequent 2.1-liter five-cylinder engine constructed 100 kW (136 hp). A complicated injection complement increasing potency and energy development. Delivery of a Audi 100 5E began in Mar 1977.
Also tip category as an aspirated diesel engine
As early as 1978, Audi presented a initial diesel version: a naturally aspirated diesel with a banishment of dual liters and producing 51 kW (70 hp). One year later, a initial turbocharged five-cylinder gasoline engine done a entrance – another pioneering attainment from Audi. With an outlay of 125 kW (170 hp) and 265 newton meters (195.45 lb-ft) of torque, it powered a new tip model, a Audi 200 5T.
The five-cylinder gasoline engine in a 1980 Audi “Ur-quattro” had even some-more to offer. With turbocharging, an intercooler and permanent four-wheel drive, it constituted a absolute technical package for a racetrack and a road. Initially, it delivered 147 kW (200 hp). In 1983, a Finn Hannu Mikkola won a drivers’ pretension in a World Rally Championship in this car. In a same year, Audi introduced a wide-track Sport quattro, that was 24 centimeters (9.45 inches) shorter. It was powered by a newly grown four-valve five-cylinder section done of aluminum with an outlay of 225 kW (306 hp). It done a Sport quattro a many absolute automobile built to date by a German association for use on open roads. The indication shaped a basement for a new Group B convene car, with a four-valve powerplant delivering 331 kW (450 hp) from a really start. It was used for a initial time in a penultimate competition of 1984, a Ivory Coast rally. The other eleven rounds of a deteriorate were contested by a Swede Stig Blomqvist in a Group B Audi quattro A2 producing 265 kW (360 hp). In a end, he won a drivers’ pretension and Audi took a manufacturers’ title.
Unforgettable: Walter Röhrl on Pikes Peak
Even after Audi withdrew from rallying in 1986 there were other racing highlights: in 1987, Walter Röhrl won a Pikes Peak Hill Climb (USA) in a Audi Sport quattro S1 (E2). The racing automobile grown 440 kW (598 hp). And a IMSA GTO excelled on a US furloughed automobile stage in 1989, delivering 530 kW (720 hp) – from small some-more than dual liters of displacement.
Audi presented another miracle in automotive story during a International Motor Show in Frankfurt am Main in 1989: a Audi 100 TDI. It was a initial prolongation automobile with a five-cylinder direct-injection turbocharged diesel engine and entirely electronic control. The powerplant generated 88 kW (120 hp) from a banishment of 2.5 liters. Audi continued to labour a operation of five-cylinder gasoline engines. In 1994, a Audi RS 2 with an outlay of 232 kW (315 hp) came on to a market. As an Avant with a energy of a sports car, it determined a new automotive class.
1994 saw a five-cylinder units crawl out of a B segment, when a Audi A4 (B5) was introduced. They were gradually transposed in a mid-1990s by a new V6 engines. The final five-cylinder engines, a 2.5 TDI in a Audi A6 and a 2.3 Turbo in a Audi S6, were phased out in 1997.
Turbo and approach injection in a TT RS
Then in 2009 there was a large quip – with turbocharging and gasoline approach injection in a Audi TT RS. The transverse-mounted engine grown by quattro GmbH constructed 250 kW (340 hp) from a banishment of 2.5 liters. The TT RS plus, that Audi presented in 2012, even reached 265 kW (360 PS).
In 2013, a RS Q3 determined a new marketplace shred as a initial compress SUV. As in the TT RS and RS 3, a engine was a transverse-mounted 2.5 liter five-cylinder. At reduction than 50 centimeters (19.7 inches) long, it was a really compress motor.
This done a long-stroke engine (bore x cadence 82.5 x 92.8 millimeters [3.2 x 3.7 in]) ideal for cross installation. Initially, it constructed 228 kW (310 PS), though reached 250 kW (340 PS) starting in late 2014. The RS Q3 opening that followed in 2016 even reached 270 kW (367 PS); in 2019, a new book of a RS Q3 brought 400 PS with 480 Nm of torque. An general jury of automotive reporters voted a five-cylinder engine “Engine of a Year” in a category 9 times in a quarrel given 2010.
Unmatched acceleration and tip speed: a 2.5 TFSI in a RS 3
Today, a 2.5 TFSI appears in a new Audi RS 3 with some-more energy than ever before. The new RS 3 models sprint from 0 to 100 km/h (62 mph) in 3.8 seconds. Their tip speed is singular to 250 km/h (155 mph), though 280 km/h (174 mph) is also accessible as an discretionary upgrade. With a RS Dynamic package and ceramic brakes, they can even strech a tip speed of 290 km/h (180 mph). That creates a Audi RS 3 the best in a category in terms of acceleration and tip speed. This is essentially due to a 500 Nm boost in torque, that is accessible between 2,250 and 5,600 rpm. That is 20 Nm some-more than a predecessor. As a result, a Audi RS 3 accelerates even faster from low rev ranges. The engine’s limit energy of 294 kW (400 PS) is accessible progressing than before during 5,600 rpm and extends over a extended plateau to 7,000 rpm. A new engine control section also increases a speed during that all of a expostulate components promulgate with any other.
