Diesels seem to be breaking their oil-burning, noisy, smokey stigmas that have haunted them for decades as more and more automakers are now offering clean diesels in their lineups. The latest huge influx of diesel models hails from Audi.

The German automaker, which is owned by Volkswagen Group, has announced a huge diesel push with 11 new TDI “Ultra” models, including the new A6 TDI Ultra detailed here. For starters, the "Ultra" in the TDI Ultra name is Audi’s designation for sustainable mobility that is fully available for everyday use — a long explanation for a TDI A6 that gets darn good fuel mileage while not hindering its common usability.

The heart of the matter is a 2.0-liter, four cylinder diesel that produces 190 horsepower and 295 pound-feet of torque that pushes the A6 from 0 to 60 mph in 8.2 seconds while achieving 53 mpg highway. With stats like that, we don’t mind hugging trees and filing up next to big rigs. Keeping all those trees happy, however, is Audi’s high efficiency SCR system that removes nitrogen oxides from the exhaust. The new system also lets the A6 pass the stringent Euro 6 emission standards with ease.

Backing the 2.0-liter TDI are two optional transmissions: a six-speed manual transmission is standard, followed by the optional seven-speed dual-clutch S tronic automatic. However, opting for the slap-paddle gearbox shoots the A6’s price up €2,250 — roughly $3,000 at the current exchange rates — making rowing your own gears sound evermore attractive.

Furthering the A6’s efficiency is the standard start-stop system and driver information center that helps keep track of good driving behavior.

Pricing for the A6 Avant TDI Ultra starts at €42,250 (about$57,000 at today’s exchange rates) and the A6 sedan TDI Ultra starts a little lower at €39,900 (around $54,000). Sales will begin sometime in the first quarter of 2014 and there are no plans yet to release any Ultra models in the U.S.

Audi A6

The standard A6 is a beautiful car through and through. Classic Audi lines exude class and elegance, while the same feel abounds throughout the cabin. Competing against the Mercedes-Benz E-Class and BMW 5 Series, the A6 definitely has its work cut out here in the U.S. market.

The A6 is powered by several engine options. The standard 2.0-liter I-4 produces 220 horsepower and is mated to a CVT. Up market from that is the same 220-horsepower engine but mated to an eight-speed automatic that sends power to Audi’s quattro all-wheel-drive system. Topping the list in for the gasoline-powered models is the 3.0-liter, supercharged V-6 kicking out 310 horsepower that comes standard with the eight-speed and quattro AWD.

The standard diesel option still exists and consists of Audi’s 3.0-liter TDI V-6 making 240 horsepower. The eight-speed and quattro are standard fare here as well.

Pricing for the A6 starts at $43,100 for the base 2.0-liter FWD CVT model. Selecting the eight-speed and Quattro with the 2.0-liter pushes the price to $45,200. The 3.0-liter supercharged V-6 starts at $55,100 and the 3.0-liter TDI starts out at $57,500.

Press Release

Audi is expanding its ultra strategy with 11 new models: Especially efficient engine versions in the A4, A5 and A6 model lines will be launched in early 2014. A new and powerful two-liter TDI will provide the drive at 100 kW (136 hp), 120 kW (163 hp) or 140 kW (190 hp); the engine emits just 104 to 119 grams of CO2 per kilometer (167.37 to 191.51 g/mile) depending on the model.

The “ultra” designation stands for sustainable mobility that is fully available for everyday use. With a combined fuel consumption rate of 3.9 to 4.6 liters per 100 kilometers (60.31 to 51.13 US mpg) and CO2 emissions of 104 to 119 grams per kilometer (167.37 to 191.51 g/mile), the new ultra models from Audi are among the most efficient cars of their segment – without any limitation on the driving dynamics or customary comfort.

Audi Board Member for Development, Prof. Dr. Ulrich Hackenberg: “The latest TDI technology, ultra-efficient transmissions, advanced exhaust aftertreatment – customers will hardly see anything, but they’ll notice the effects of powerful acceleration and, thanks to extremely low fuel consumption, when paying at the gas station. The Audi ultra models score points with big advantages for everyday operation – just what customers appreciate.”

The A4, A5 and A6 families come with the 2.0 TDI. Newly developed in many areas, it affords exemplary efficiency and power. The high torque (320 or 400 Nm [236.02 or 295.02 lb-ft]) ensures sporty power generation even at low engine speeds, along with low fuel consumption.

Audi Head of Powertrain Development, Dr. Stefan Knirsch: “An innovative, highly efficient SCR system removes nitrogen oxides from the exhaust. This measure means that the new ultra models will of course meet the future Euro 6 emission standards while achieving lower fuel consumption.”

Standard on the ultra models is a manual transmission that makes the gear ratio somewhat taller in the upper gears. Optional on the A6 is an innovative seven-speed S tronic that further reduces the average consumption rate to 4.4 liters per 100 kilometers (53.46 US mpg) with 4.6 liters on the Avant (51.13 US mpg). This corresponds to a CO2 emission of only 114 grams per kilometer (183.47 g/mile) and 119 grams (191.51 g/mile) for the Avant. This completely redesigned dual-clutch transmission launches a new generation, distinguished by high efficiency as well as by especially fast and comfortable gear changing. The innovations include minimized internal friction, highly efficient oil supply and a centrifugal pendulum-type absorber that counteracts undesirable vibrations and allows low-noise driving at very low engine speeds. A harmonious gradation of the gears in interplay with the wide spread provides comfortable driving. The seven-speed S tronic as well as the six-speed manual transmission conducts the power to the front wheels.

The standard start-stop system and the driver information system with efficiency program make an important contribution to the economy of the new ultra models from Audi. On the A4 and A4 Avant, modifications of details in the aerodynamics and a lowered body also optimize the fuel consumption.

This combination of efficiency measures yields trend-setting consumption and emission figures: from only 3.9 l/100 km (104 g/km) [60.31 US mpg / 167.37 g/mile] for the A4 Sedan (100 kW), 4.2 l/100 km (109 g/km) [56.00 US mpg / 175.42 g/mile] for the A4 Avant (100 kW) and A5 Coupé (120 kW) and 4.3 l/100 km (111 g/km) [54.70 US mpg / 178.64 g/mile] for the A5 Sportback (120 kW). The A5 Sportback 2.0 TDI ultra with 100 kW of power will follow a bit later. With no restrictions on equipment, the A6 2.0 TDI ultra achieves the especially low CO2 emission level of 114 g/km (183.47 g/mile) with 117 g/km (188.29 g/mile) with manual transmission. Per 100 kilometers it consumes on average 4.4 liters of fuel (53.46 US mpg) and 4.5 liters (52.27 US mpg) with manual transmission. Its Avant sister model manages with 4.6 l/100 km (51.13 US mpg) with 119 g/km (191.51 g/mile), irrespective of the transmission.

The new ultra models will go on sale successively from the first quarter of 2014. The 100 kW version of the A4 starts at €32,600, the A4 Avant at €34,250. With a 120 kW engine, prices for the A4 begin at €34,700, for the A4 Avant at €36,350. The A5 Sportback is available for €37,350 and the A5 Coupé for €38,150. The A6 is priced at €39,900, the A6 Avant at €42,250; the prices for both model versions with S tronic is €2,250 more.

The ultra range from Audi also includes the A3 1.6 TDI ultra, that had its debut as the first ultra model in fall 2013. It consumes on average just 3.2 liters of fuel per 100 kilometers (85 grams of CO2 per kilometer) [73.50 US mpg / 136.79 g/mile]. All ultra models are visually identifiable by the discreet lettering at the rear.
