Audi Introduces New Evolution of 2.0 TFSI at Vienna Motor Symposium

This year’s Vienna Motor Symposium was a prolific event for the Volkswagen Group, introducing or at least previewing multiple engine configurations from a turbocharged W12 producing 600hp, to a 1 liter, three cylinder with WRC roots that’s good for about 268hp. On the more common side of things, Audi introduced the latest evolution of their 2.0 TFSI, which will power the next generation A4.  That said, the likelihood for this engine to become available in Volkswagen models like the EA888 and EA888 Valve Lift before it is quite good.  Coming in at just over 300lbs and capable of producing 190hp/236 ft-lbs of torque while returning 47mpg, it’s safe to say that the future for this powerplant is quite a bright one.

Read the full Press Release below.

  • New 2.0 TFSI four-cylinder engine with innovative combustion method
  • Top figures: 190 hp, 320 Nm (236.0 lb-ft), less than 5 l/100 km (47.0 US mpg)
  • To be implemented in the new Audi A4 by the end of 2015
  • Prof. Dr. Ulrich Hackenberg: “A prime example of the Audi rightsizing strategy”

Audi presents the most efficient two-liter gasoline engine in its class. The new 2.0 TFSI with 140 kW (190 hp) demonstrates the engine expertise of the brand – with a ground-breaking new combustion method. Audi will be using the engine for the first time in the next generation of the A4.

2.0 TFSI mit 140 kW (190 PS)Over ten years ago, Audi was the first manufacturer worldwide to bring the TFSI engine with turbocharging and direct injection into series production. This made the brand with the four rings the trendsetter in downsizing and downspeeding. “We’re now taking a crucial step further with rightsizing,” said Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at AUDI AG.  The reduction in displacement and engine speed can be optimally effective only if reasonably related to the vehicle class and the customers’ everyday use, explains the Technical Director. “Rightsizing thus involves the optimal interplay of vehicle class, displacement, output, torque and efficiency characteristics under everyday conditions. Our new 2.0 TFSI is a prime example of Vorsprung durch Technik.”The four-cylinder engine draws 140 kW (190 hp) of power and 320 Nm (236.0 lb-ft) of torque from a displacement of 1,984 cc.  Because the high torque is applied in a wide speed range of 1,450 to 4,400 rpm, every customer will benefit from the constantly accessible, high pulling power of the engine. The engine also boasts of groundbreaking low fuel consumption levels. With consumption levels less than 5.0 l/100 km (47.0 US mpg) in the NEDC, the four-cylinder engine clearly undercuts its predecessor and comparable competitors.
Technology in detail:
The breakthrough of the 2.0 TFSI lies in a new combustion method. At its core its principle is comparable to the Miller cycle. Audi engineers have further developed that method in crucial ways, however. The increase in efficiency is based on the following factors:
  • The intake time has been significantly shortened (140° crank angle (CA) rather than 190 to 200° CA).
  • Owing to a higher boost pressure on the inlet side, the engine attains optimal cylinder charges despite the shorter intake time.
  • The intake valve also closes earlier – well before the bottom dead center is reached. This lowers the medium pressure, allowing a high, efficiency-boosting compression ratio.
  • In the partial load range, an additional injection upstream from the intake valve yields an efficient mixture formation that is already complemented by the direct injection in the intake manifold and in the combustion chamber.
  • The Audi Valvelift System (AVS) on the inlet side allows a short intake time at partial load and a longer time at higher loads (full load: 170° CA).

Dr. Stefan Knirsch, Head of Engine Development at Audi, sums up the benefits of the new engine: “Thanks to this rightsizing approach, the new engine enjoys the consumption benefits of a downsizing engine in partial load operation, while at higher loads it has the advantages of a large-displacement engine. The result is optimal efficiency and performance characteristics across the entire engine speed range.”

Beyond the new combustion method, the new engine, with a weight of only about 140 kg (308.6 lb), avails itself of other efficiency technologies. For example, the coolant flow is controlled so as to greatly shorten the engine warm-up time. Contributing to this benefit is also the exhaust manifold, integrated in the cylinder head. The consistent reduction of friction as well as the use of low-friction engine oil (0W-20) also increases efficiency.

The comprehensive package of high-tech solutions makes the new 2.0 TFSI a real high-efficiency engine that sets a new benchmark in its segment. Audi will be introducing the new generation of engines first in the new Audi A4, and then in other model series.

Fuel consumption of the models named above:

Audi A4:
This vehicle is not yet on sale. It does not yet have type approval and is therefore not subject to Directive 1999/94/EC.

Waterfest Moves to Atco Dragway

Waterfest 24 will be held at Atco Dragway, in Atco, New Jersey. The summer event will take place at its new venue on July 21 and 22. Long held in Englishtown, New Jersey, the festival has been such a large part of the VW scene that the latest iteration of the Golf even comes with optional “Englishtown” wheels . The new venue, however, is an NHRA drag track a scant 52 miles southwest of Englishtown. The ¼ mile drag track opened in 1960, which makes it the oldest drag strip in New Jersey. The announcement came today on a social media post that announced the new location. Waterfest is North America’s largest VW/Audi show. As many 20,000 people show up for the annual show, making the second largest show in the world—with Worthersee being number one. 2018 will be Waterfest’s 24 th year in existence.

Macau Gets Messy with 16-Car Pileup

The Macau Grand Prix is always good for an accident or two or 16— you may remember Audi’s race ending crash last year —and this year’s event didn’t disappoint. It didn’t take long for things to get messy on the tight road circuit. On the opening lap of the qualifying race a 16-car pileup caused the race to be suspended. Things kicked off when Daniel Juncadella hit a wall on the exit of Police bend, one of the tightest parts of the already tight circuit. The following car of Raffaele Marciello was able to avoid the carnage, but Laurens Vanthoor, who was in the upside-down Audi that ended the race last year, could not avoid Juncadella and together they blocked up the road pretty much completely. “I couldn’t see him [Juncadella] at first. Then I saw the car standing still,” Vanthoor told Motorsport. “I tried to brake but it was just understeering and I couldn’t do anything. There’s room for one car there and you’re blind.” Fourteen more cars would eventually crash into the corner c

The First of its Kind: Integrated Engineering Releases Highly-Anticipated IE450T MK6 Golf R Turbo Kit

After two long years of development, the team at Integrated Engineering has finally announced the release of their IE450T kit for the MK6 Golf R. With their turbo kit bolted on right out of the box, the sport AWD hatch is transformed into a 450bhp monster, with hardly any noticeable increase in spool time. In fact, 435 ft-lbs of torque are achieved at all four wheels, at a mere 3300rpm! By now you are probably asking yourself how this is even possible on a 2.0L engine that made nearly half that power from the factory. By employing true twin-scroll technology into the cast turbo manifold and pairing it with a state-of-the-art BorgWarner EFR turbocharger, IE was able to keep spool time at a minimum and bring the fastest-spooling big turbo setup to the market. “We wanted to offer a kit that would dramatically increase the power output without making the car lose its amazing street-friendly drivability,” mentioned one of the IE engineers. We are told the IE450T leaves the car driving jus
