New 'e' drivetrain rates 4.6 liter/100 km and will also be available for the A4 Avant but is not scheduled for a US release

The German premium brands are certainly putting their workhorse 2.0 liter diesel engines to the test these days. Doing their best to up their overall economy/emissions ratings by placing ever-improved versions of those light drinkers into their compact and medium-sized sedans.

The latest is Audi, who's A4 2.0 TDI e claims a mileage rating of 4.6 liter/100 km, or more than 50 mpg US (51.13 mpg, to be exact) and CO2 emissions of 119 g/km.

With the "e" likely standing for "efficient," the A4 2.0 TDI e comes with VW Group's standard 2.0 liter engine with 136 bhp but tweaked for better fuel economy. It features stop-start technology, an onboard computer that coaches the driver to maximize efficiency and a 6-speed manual transmission with a raised final-drive ratio which reduces engine speed in each gear.

The A4 Avant model will also be available as an "e" model with the same engine.

Oh, don't let that 50 mpg US rating fool you about a North American release for this A4 "e". Audi is just boasting about cracking that milestone. This Audi isn't headed to the US market to go up against the 50 mpg Toyota Prius, although it should. The A4 2.0 TDI e is a European model and it is not (yet) scheduled for a US release.

The A4 2.0 liter TDI e goes on sale in early June with a starting price of 30,800 euros.

The new diesel-powered Audi A4 consumes a mere 4.6 l/100 km (51.13 US mpg)

  • Emissions of just 119 grams of CO2 per kilometer (191.51 g/mile)
  • Market launch in early June at a price of 30,800 euros
  • A4 Avant also available as an ‘e’ model

Audi will soon launch the most efficient standard-size sedan. The Audi A4 2.0 TDI e will be available at dealerships starting in early June. Equipped with a 6-speed manual transmission, this sedan sips 4.6 liters of diesel per 100 kilometers (51.13 miles per U.S. gallon). It consequently emits a mere 119 grams of CO2 per kilometer (191.51 grams per mile): the best value of any vehicle in its class. “Efficiency is standard in every Audi. The A4 2.0 TDI e is particularly persuasive proof that efficiency, outstanding performance, comfort and driving enjoyment are not mutually exclusive,” says Michael Dick, Board of Management Member for Technical Development at AUDI AG. This ‘e’ model develops an output of 136 bhp (100 kW); it reaches 100 km/h (62.14 mph) in 9.5 seconds and swiftly tops out at 215 km/h (133.59 mph). The sedan can be ordered now and costs 30,800 euros. This remarkably efficient A4 is also available as an Avant.

The combined impact of several features facilitates the vehicle’s increased efficiency. The standard start-stop system is especially effective during city driving. As soon as the vehicle comes to a stop, the shift lever is in neutral, and the driver removes his or her foot from the clutch pedal, the system turns the engine off. The engine then turns back on as soon as the clutch pedal is depressed.

The start-stop system functions extremely quietly, smoothly, and quickly. While the driver is stepping on the clutch pedal to shift into first gear, the engine instantaneously returns to its idle speed. In the standardized driving cycle, the start-stop system reduces fuel consumption by some 0.2 liters/100 km, which equates to about 5 grams CO2/km (8.05 g/mile).

Furthermore, this ‘e’ model features a 6-speed manual transmission with a final-drive ratio higher by five percent — enabling a reduction in engine speed in each of the six gears. The engine-management system has also been modified for maximum efficiency. The fuel-saving low-resistance tires (205/60 R 16) improve rolling resistance and are exclusive to the A4 model line’s ‘e’ model. Standard equipment also includes the recovery of braking energy. Aided by intelligent alternator regulation, this system converts surplus kinetic energy to electrical energy during a vehicle’s braking phases. This electrical energy is temporarily stored in the electrical system’s battery. When the vehicle resumes acceleration, the battery supplies this stored energy to the vehicle’s network — reducing the load on the alternator and thus saving fuel.

An on-board computer with efficiency program is also part of the standard-equipment package. The driver information system with gearshift indicator and efficiency-data display notifies the driver when it is sensible to shift gears to conserve fuel. The on-board computer displays all fuel-efficiency data on the center screen. These recommendations enable drivers to conserve fuel to the tune of 30 percent — simply by modifying their particular driving habits. Audi’s efficiency program continuously analyzes the vehicle’s energy consumption and gives the driver situation-specific advice on how to optimize fuel efficiency based on the given driving situation or driving style.

The A4 2.0 TDI e also consumes less fuel thanks to enhanced aerodynamics made possible by additional aerodynamic-drag optimizations such as an underbody trim panel, the partially enclosed radiator grille, and the reduction in ride height of 20 millimeters (0.79 inches) facilitated by the sports chassis.

The A4 2.0 TDI e is also available as an Avant. Its combined fuel consumption amounts to just 4.9 liters of diesel per 100 kilometers (48.00 miles per U.S. gallon). This Avant consequently emits 129 grams of CO2 per kilometer (207.61 grams per mile). The basic price for the Avant is 32,800 euros.

The Most Efficient Audi Models

The A4 2.0 TDI e is the fourth Audi ‘e’ model. Another ‘e’ model is the Audi A3 1.9 TDI e, available as a three-door hatchback or a five-door Sportback. It consumes 4.5 liters of fuel per 100 kilometers (52.27 miles per U.S. gallon) and emits 119 grams of CO2 per kilometer (191.51 grams per mile). As a three-door model, the Audi A3 1.4 TFSI with start-stop system also achieves outstanding values, with fuel consumption at 5.7 l/100 km (41.27 miles per U.S. gallon) and CO2 emissions of 132 g/km (212.43 grams per mile). In the business sedan segment, the Audi A6 2.0 TDI e, available as a sedan and Avant, emits just 139 grams of CO2 per kilometer (223.70 grams per mile) while consuming just 5.3 l/100 km (44.38 miles per U.S. gallon). The Audi A8 2.8 FSI e was the first luxury sedan to remain under the threshold of 200 grams of CO2: 199 g/km (320.26 g/mile) at 8.3 l/100 km (28.34 miles per U.S. gallon). Although there is no ‘e’ in the model designation of the Audi TT 2.0 TDI quattro, it has attracted a lot of attention as a diesel sports car. The coupé’s fuel efficiency of 5.3 l/100 km (139 g/km CO2) [44.38 miles per U.S. gallon (223.70 g/mile CO2)] sets a benchmark in the sports-car segment. It accelerates from 0 to 100 km/h (62.14 mph) in just 7.5 seconds and reaches a top speed of 226 km/h (140.43 mph).

the prius and honda hybrids are just marketing hype.prius has several times carbon footprint than non hybrid vehicles, it uses more fuel than european diesel cars, is a not a nice drive (unless you're a senior citizen only going to local bowls club !). Reality is toyota/honda have jumped onto the greenie eco band wagon to get prominence in world markets. Dont be under any illusion that the ABM (AUDI,BMW,M/BENZ)have not been very busy beavering away with alternate propulsion/power/fuel technology long before asian car industry. Fossil fuels will expire within 50 years anyway. What about the tons of fossil fuels used in current wars, jet planes, cargo vessels, cargo trucks,railroads etc etc.???? Private motorists who are a ready source of govt.taxes get hammered all the time.

This is EXACTLY the kind of vehicle many guys in my age bracket (35-45) would buy. Good-looking (well, not in friggin' PINK...), high-quality, efficient, fantastic interior, with a manual transmission. Many Jetta TDI owners have well over 200,000 miles on their vehicles because the cars WORK, but owners won't trade "up" to petrol-engined or automatic-transmissioned vehicles. C'MON, Audi, M-B, and BMW, let's see some quality manually-shifted diesels for the USA! We constantly hear the Europenas trash US drivers as gas-wasting, SUV-driving pigs... but it's only because M-B, BMW, and Audi don't have the balls to market their efficient quality stuff here. Get it done, already! (rant is now off).

The Audi A4e really should come to the US, that way people can maintain their self-respect and fuel efficiency at the same time. Let's face it, the Prius is the most horrendous looking, among the most underperforming cars available on the American market.

Curious to know how many are waiting for bmw and audi to bring their four cylinder turbo-diesels over to the US? Am I the only one willing to drive a 3er, 5er, A4 or A6 with a high output 2.0 liter turbo-d? 523d is my number!!!

Great! except for the fact that people who pay €30,800 might not care about prius-like fuel economy.
