Meet AMG's M139, the Turbo Four-Pot Packing V8 Power

... with the 369lbft peak arriving at 5,000rpm rather than 2,000rpm as before. This, says AMG, creates a power delivery more akin to a naturally aspirated engine than the diesel-like burst of the M133.

That sounds like music to my ears.

Yeah, that's the most interesting part of the new engine to me. The obsession with pushing the peaks down the range as much as possible has been a relatively modern move, coming along with decreased turbo lag. Don't get me wrong, I see the advantage for everyday motors, but it does rob sports cars of that feeling of specialness.

Still not sold on the new A, and I don't remember a single truly glowing review of the last 45, but it will be interesting to see how this one goes.

Give it a REAL intercooler. Another 60-80hp

Lancer Evo X FQ-440 MR? *runs*

Lancer Evo X FQ-440 MR? *runs*

Although a little way short of the most powerful four-pot in a road car, the M139 is a series production engine that doesn’t require tiny service intervals to keep it going.

FQ-440 was that very engine - 40-car run for the UK only, 434hp (and 410lbft), and 4,500-mile intervals

Fair enough. Will that AMG engine fit my Honda?

Nevermind.

Because these sorts of comparisons always fascinate me, that's more power (but not always more torque) than the:

• AMG Hammer
• E39 M5
• C5 Corvette Z06
• Ferrari 360

Jeebus.

I think it should be noted that the M139 will be running 30.5psi (2.1 bar) of boost pressure.

I used to think the Abarth 1.4T's 26psi was crazy for an OEM engine.

I wonder how the gas mileage would compare to a C5 Z06 when they are both at peak load. I'm willing to bet the LS6 would do better, if only because it would undoubtedly be running a far-leaner fuel mixture.

If you want a laugh, Mercedes included in the press release a figure I've never seen before:

Max. air mass throughput - 1,200 kg/h (S-model)

Yup, this can suck in 1.2 tonnes (1.18 tons, 1.32 short tons) of air an hour. There, that's a thing you know now.

Can only hope it looks better than the old model.

If this engine is running a 12:1 A/F ratio, that means 100kg of fuel, equivalent to 132 liters (or 35 gallons) per hour fuel consumption at max load. Dayum.

*I think the above is correct, unless something I've assumed is wrong.

Too bad the Daimler/Nissan relationship seems to have fallen apart post-Ghosn, could’ve been an interesting option for the next Z. Also would’ve made a good engine for the SLK (or whatever C they’re calling it now) which seems like it’s dead now as well.

I still have the car guide for the same year that the Ferrari 360 and Porsche Carrera GT were out...

The 360 will always be my favorite Ferrari lol.

 

[Maxx2013]

Wow, as much as I like the sound of V8's and other big engines, there aren't really a whole lot of reasons to get anything larger than a 2.0 nowadays, especially in places where taxes are high for bigger engines.

 

[Beeblebrox237]

I love the idea, on paper, that you can buy a car with a smaller engine than a 2005 Chevrolet Cavalier but that makes more power than a 6.0L 2005 Corvette. In practice the Corvette probably has a much more charismatic engine, but it's an interesting stat nonetheless. I'll be more interested in the chassis of the A45 than the engine, to be honest, since we already knew the engine would make silly power.

 

[homeforsummer]

The A35 has a pretty good chassis, far better than the last A45, so I'm hoping for good things from the A45. I can't forsee a situation where I'd really be interested in a car like the A35 but even more powerful - it already feels pretty brisk with 300-odd horses - but I guess that's never stopped anyone before.

Yeah, but the A45 is 10 more than the A35 so it must be superior.

 

[kikie]

I want this custom paint job.

 

[DriveSpark]

Engine sounds good. I'm still struggling with the front end of the enw A class, there is just something off about it to my eye.

I'd like to see a 3 door shell for the A45 too, but I doubt it'll happen.

Pricewise I'd be surprised if its under £40k, 45k would not surprise me.

Spoiler: Warning: Shmee 150 Alert!!!!!!!!!!!!!!!!

[FT-1]

Both models look sooo good with the panamericana grille.

 

[VXR]

I've seen the GLC with that grille before and it looks fantastic on that, too. Like a crossover GT.

 

[Aphelion]

Dang... the coupe looks exceptional. Way to flip flop all over the place with the design quality mercedes.
