The powerplant that outputs 105 hp is very efficient with fuel mileage recorder at 57.37 mpg or about 4.1L going for 100km. The carbon dioxide per kilometer emission is also excellent at 109g. The impressive figures were made possible with technologies implemented like the energy recovery setup and the start stop system.

The fuel economy of the A3 was improved by 3% due to the energy recovery technology which basically utilizes the kinetic energy of the car’s brakes while slowing down. The energy gathered is used to rid the alternator of its load. The alternator uses the resources of the engine which inevitably consumes fuel in the normal process.

The 105 hp variant zooms the A3 from 0 to 62 in a matter of 11.4 seconds and can max to a speed of up to 121mph. The 90hp has a torque of 170 lb-ft and dashes the 62mph mark on the tick of 12.9 seconds. The lower powered engine does not have the start stop technology but has decent 52.57mpg fuel efficiency and has a rating of 118 g of carbon dioxide per kilometer.

The 2009 Audi A3 with a 90hp engine sells for €22550 while the 105hp variant has a sticker price of €23550.

The Audi A4 Allroad Quattro converts mechanical power to electricity whenever it decelerates. This translates to a reduced load on the alternator.

On top of the power regeneration system, all three Audi engines are also Euro 5 compliant. The 2- and 3- liter diesel TDI engines come with a six-speed manual transmission. Meanwhile, the 2.0-liter TFSI engine, on the other hand, comes with a seven-speed S-tronic transmission.

All Audi A4 Allroad Quattro versions are designed as permanent all-wheel drives. It houses a purely mechanical center differential which puts more power on the rear wheels, distributing 40:60 ratio of power with the front axle.

The three engines consume competitively low amounts of fuel. The 2-liter TDI diesel engine consumes only 6.4 liters per 100 km, while the 3-liter V6 TDI diesel engine consumes 7.1 liters for every 100 km. If you take in account some extra fuel efficiency tips, I’m sure you might even do a little better.

The gasoline engine consumes a higher amount of fuel, but it’s still competitive for its make. The 2-liter TFSI engine runs on 8.1 liters of gasoline for every 100 km.

The models boast of high straight-line stability, impressive riding comfort, and excellent driving dynamics. These benefits are fruits of several modifications made in the line up: the car’s front axle was reposition to be nearer the axle, and the differential was placed directly in front of the clutch and behind the engine. These improvements made way for better overall weight distribution.

But common notions dictate that Americans are so used to gasoline. The challenge for Audi now is with the buying market, will they prefer diesel?

The vehicle has turbocharged V6 engine with 3.0 liter. It has been packaged by the company as something reliable for drivers at the same time clean and fun to use. The catch is that though it has similar skins of a crossover, it is powered with diesel. This makes up to a difference of almost $3,000 compared to the old one.

With a torque that’s 405 lb-ft, some reviewers question its practicality for short distance travelers. True enough, Audi wants to prove that it sticks to the way it is packaged. With enough space in the back part of the vehicle for gears for long travel, Q7 3.0 TDI would make a good transportation for road trippers or for those who regularly take a long distance trip.

On engine talk, the unit rates at 225 horsepower. Mix that with the torque; this unit can peak at 130 mph. It can even perform from 0-60 in just 7.9 seconds. Something suburban drivers or car owners may like.

Technically, this unit is good enough. It has a low-end torque that is still satisfying.
Gas or diesel, consumers may overlook this issue. Audi chooses to dwell on issues like practicality and performance.

First presented in the US at the Detroit Motor Show in 2007, I’ve been looking at this beauty ever since… Audi claims more power output with lower fuel consumption than any of the gasoline versions currently heading sales in the US thanks to this Diesel engine producing 500 horsepower.

The looks… THE LOOKS… It’s by far the best looking Audi ever built (okay, maybe there’s an R8, … tough one ).

Enjoy these spectacular pics.
