Thanks to Turo for sponsoring this video!
Mercedes AMG has cranked out a gem of an engine. The hand built M139 is a 2.0L turbocharged inline four-cylinder that makes 416 horsepower! That makes it the most powerful turbo four-cylinder engine currently in a production car! The M139 engine is used the Mercedes GLA45, CLA45, and A45 vehicles. 416 horsepower at 6,750 RPM and 369 lb-ft at 5,000 RPM. With a displacement of 1991 cc, the M139 makes over 208 horsepower per liter! It also has some of the highest peak combustion pressures of any engine.
How did Mercedes do it? Clever engineering. From the engine layout, to the roller-bearing twin-scroll turbos, to the block and forged internals, to the cylinder head, to the spray on cylinder liners, the engine is packed with brilliant engineering features. How does it all work? Check out the video for full details!

    Hi. I just bought a brand new merc a45s from the dealership - abudhabi uae- and they told me you can drive it as you wish and no need at all for a break in period, but as you know the factory instructions say otherwise! So should i follow the dealership advice or the factory instructions? I drove it as per factory instructions for 750 km so far and can't wait to put it in race mode and step on the throttle

    Not even close. The 2.3L Ford only makes 350 HP. This is a 2.0 that makes 416. They are both turbocharged engines. (I do love the Focus RS. I just wish the American companies would focus on performance turbo 4 cylinders again).

    Like really?? Mitsubishi did this already in 2007-2008 with the last gen Evo. Rotated the engine, intercooler in front, turbo in the back. Split manifold, twin scroll turbo... it like really 10+ year old tech. In a production car, and made those power numbers not even going over 30 psi, in stock car, with factory warranty (UK fq400 models)

    Thanks for the video, as always great representation. So many good things going on here: twin scroll with roller bearings, closed deck, high boost, port/DI injection, exhaust rotated to the firewall (heat is pushed out of the engine bay naturally), but there's always have to be something to hold it back. With all the effort and no iron sleeves? Cutting corners everywhere. Time will tell, but I'm skeptical. Haven't seen those to hold up. I bet it has one piece low friction oil rings too. I see it start burning oil before 50k miles and dealer of course is going to say it's normal.

    VW could easily build a 400HP EA888 engine as we know they did with the Golf R400 concept that would have been a production vehicle had Dieselgate not slashed funding. I wish Mercedes had just developed a I-5 for their “45” AMG cars instead of the I-4. Not only would the I-5 sound better, but it would be able to produce more power under less stress and Mercedes has a storied history of I-5 engines, albeit diesels, but still... for the sake of history! It also would be interesting to see the power and torque war between Audi and Mercedes go to new levels as introducing a new I-5 for the 45AMG models would have been like declaring war on the RS3/RSQ3/TT-RS.

    Still getting details wrong eh? Closed deck blocks still have full size coolant passages around the cylinders just like open deck blocks. The only benefits of open deck are that the top 3mm of the cylinders get coolant contact (big whoop) and it's cheaper to manufacture.

    Naturally Aspirated, or Super Charged engines are more reliable. Turbos are connected to the Down Pipe, which is connected to the exhaust system for back flow pressure to spool the turbines. Back flow coming from exhaust leads to Carbon Build Up Check Engine Light turns on at 38,000 miles (after manufacturers warranty) Thus, locking Turbo Blades and internal veins, restricting air and boost. From my experience I learned the hard way, it was great for 3.5 years (after factory warranty ended) fuel mileage average was 32 mpg and dropped significantly to 8 mpg to 12 mpg. Good luck with your Turbo replacement.

    Cars are getting closer to motorcycles in HP per litre. Most top of the line sports bikes pull 200hp+ from a 1000cc engine so a 2000cc engine will need 400hp to match the bikes and it would appear Mercedes has done this with a 416hp from a 2000cc engine. However the bikes do it with a NA tune and the car needs a turbo. What about a bike company that puts a Super Charger on their bikes? Well Kawasaki does this with the H2R and pulls 325hp from a 1000cc engine, so if the cars want to keep up then Mercedes needs to pull 650hp from this engine. Sorry buddy I'm not buying a car until they get faster. PS. I am aware there are cars faster than a motorcycle but these cars usually cost $1 million USD or more.
