Mercedes-Benz AMG 6.2-liter V8 – Click above for all winners

The 2010 International Engine of the Year awards have been announced and ten different engines have been honored in 11 categories, plus an overall winner chosen. The engines were rated by a jury of automotive journalists from around the world and range in size from sub-1.0-liter three cylinders to a 6.2-liter V8 and go from mild to wild. Not all are available in North America yet but at least two more of these engines are expected to arrive here within the next year. Go ahead and view the gallery to check out this year's winners in each category and find out which engine the jury considered the best overall for 2010.

  • Best New Engine of the Year: For best new engine, the jury selected the new Fiat 1.4-liter Multi-Air inline-four. The Multi-Air technology was developed Fiat as a mechanism to provide infinitely variable valve timing and lift control and it can be easily adapted to existing engines. Fiat has plans to add Multi-Air to most of Chrysler's engine lineup in the next couple of years.
  • Green Engine of the Year: The top green engine award again went to Toyota for the 1.8-liter hybrid powertrain that debuted in the third generation Prius last year. Toyota has managed to get both improved efficiency and performance out of the latest iteration of its pioneering powertrain.
  • Best Performance Engine and Best Engine above 4.0-liters: In order to make a special car, you need to start with a special engine, and its hard to go far wrong with a high-revving V8. That's the path AMG chose when it decided to develop a new engine from the ground-up and the M156 6.2-liter V8 has been recognized as the best performance engine by the International Engine of the Year Awards.

    The V8 is used in all of Mercedes-Benz' rear-wheel-drive AMG models, from the C63 to the SL and even its SUVs, with power output varying from 478 horsepower to over 525 depending on the application. A modified version is even used in the SLS AMG with 571 hp. In addition to the performance award, the M156 was also honored in the category for engines over 4.0-liters. Over the next few years, AMG will be phasing out this engine in favor of a new twin-turbo 5.5-liter V8 that will be even more powerful and fuel efficient. Here's hoping it doesn't lose its character in the process...
  • Sub 1.0-liter: The 993cc inline three found in the European market Toyota Aygo, Citroen C1 and Peugeot 107 weighs in at a remarkably svelte 147 pounds and produces 67 hp. It's far more refined than the similar sized triple in the Smart and easily won the category.
  • 1.4- to 1.8-liter: The 1.6-liter turbocharged inline-four in the Mini Cooper S provides an outstanding combination of performance and fuel efficiency. With 175 horsepower it gives the Mini plenty of scoot while still delivering 30+ mpg.
  • 1.8- to 2.0-liters: The BMW twin-turbocharged 2.0-liter inline-four diesel delivers 204 horsepower and a stump-pulling 295 pound-feet of torque. It powers the 123d to 60 mph in 6.5 seconds and delivers 37 mpg even when being thrashed. What more could you ask for? How about a 323d Touring?
  • 2.0- to 2.5-liters: The 2.5-liter TSI inline-five from the Audi TT-RS clearly demonstrates why most automakers are scrambling to develop turbocharged and direct injected engines. With a peak power delivery of 340 horsepower and a torque curve that flat-lines at 332 pound-feet all the way from 1,600 to over 5,000 rpm this engine slings the TT-RS to 60 mph in 4.7 seconds while returning 25.6 mpg.
  • 2.5- to 3.0-liters: The BMW N54 has been one of our favorite engines ever since it debuted with 300 horsepower and 300 pound-feet of torque. It provides seamless power delivery from its perfectly balanced inline-six layout and uses two turbochargers to give quick response and torque everywhere. The N54 is being phased out of most applications this year in favor of an equally powerful N55 with a single twin-scroll turbo, direct injection and valvetronic for even better response and fuel efficiency.
  • 3.0- to 4.0-liters: The BMW S65 4.0-liter V8 can only be found in the lovely M3. At idle and around town, it provides a pleasantly muted tone that won't draw undue attention to itself. But drop the hammer and it turns up the volume in the best possible way.
  • Overall best engine and best 1.0- to 1.4-liter: For several years now Volkswagen has offered a range of 1.4-liter TSI inline-fours in much of its European lineup. These boosted and direct injected engines deliver surprisingly robust torque for such small engines with great fuel economy. At the top of the range is the engine selected as overall best by the jury, the 1.4 TSI TwinCharger. While the lesser engines rely on just a turbocharger, this unit adds a mechanically driven supercharger to a larger turbocharger for an even broader response curve. The maximum output is 178 horsepower and combined fuel economy in the Golf is 38 mpg!

Stuttgart/Affalterbach – The AMG 6.3-litre V8 engine took away two top accolades as part of the coveted "International Engine of the Year Awards 2010": the high-revving naturally aspirated engine developing up to 386 kW/525 hp comfortably took top spot in the "Best Performance Engine" and "Above 4 litres" categories. This is the second year running that the eight-cylinder engine from AMG has beaten off the competition.

Bearing the internal designation M 156, the AMG 6.3-litre V8 engine with its displacement of 6208 cubic centimetres produces between 457 hp and 525 hp, develops up to 630 Nm of torque and features in various AMG models, including the C 63 AMG, the E 63 AMG and the SL 63 AMG. The basis for the agile power delivery is the consistent technology transfer from motorsport, which has been an inseparable part of the company philosophy at Mercedes-AMG for over four decades. The verdict of juror Jason Cammisa from Automobile Magazine (USA): "The absolute epitome of a German hot rod V8 engine!" Carl Cunanan, editor of C! Magazine (USA): For its fantastic engine sound alone it deserved first place!"

The great potential of the award-winning AMG V8 is also reflected in its character-packed, powerful evolution: the engine – dubbed the M 159 – for the SLS AMG super sports car is based on the M 156; in the gullwing the AMG high-revving naturally aspirated engine develops 571 hp and delivers maximum torque of 650 Nm. Another outstanding vehicle is the C 63 AMG with Performance Package Plus and maximum output of 487 hp. The overhauled features inside the engine are responsible for the increase in output: the forged pistons adopted from the SLS AMG together with new connecting rods and a lightweight crankshaft make the engine three kilograms lighter. The reduced inertia enhances the agility of the eight-cylinder unit, which offers even more exhilarating responsiveness.

Mercedes-AMG beats off established rivals

The "International Engine of the Year Awards" rank among the most prestigious honours in the automotive sector and have been organised by specialist UK publisher, UKIP Media & Events, since 1999. An independent jury of 65 renowned motor journalists from 32 countries chooses the best engines of the year. Following on from the success in 2009, the AMG 6.3-litre V8 engine also managed to beat off prestigious rivals from Germany, Italy, the UK, USA and Japan this year, enabling Mercedes-AMG to demonstrate once again its consummate expertise in developing and producing exhilarating high-performance engines.

Friedrich Eichler, Head of Engine & Powertrain Development at Mercedes-AMG:

"Our renewed success this year in the two categories is testimony to the out-and-out positive test results for the AMG6.3-litre V8 engine in all the media. The top spots also reflect the great enthusiasm of our customers."
