Spotted this A200 AMG Line being used as a driving school car. And look! 6-speed manual transmission.

Specifically, the S version of the M 139 makes 416 hp at 6,750 rpm and 369 pound-feet (500 Newton-meters) of torque between 5,000 and 5,250 revs. The redline hits at 7,200 rpm.

There's also a standard variant of the M 139 that produces 382 hp (285 kW) at 6,500 rpm and 354 lb-ft (480 Nm) between 4,750 and 5,000 rpm. The redline is the same 7,200 revs.

Both versions of the M 139 use a twin-scroll turbocharger. The S variant can produce up to 30.5 psi (2.1 bar) of boost, but the standard model goes to 27.6 psi (1.9 bar).

What's the difference between M133 and M139 engine? Both have 1991ccm.
I see that M139 has 160kg but 4.0l V8 has like 207kg, don't know why the difference isn't bigger.
For base 45 AMG power is up by 6hp and 5Nm, I thought it will stay the same so this is good.

The AMG "45" models engine detailed:

I had a hunch that the A45 would get a new or heavily reworked engine as chucking a bigger turbo on the predecessor's engine would have resulted in even more lag and worse engine elasticity.

 

[DjordjeC63]

That base version is unnecessary since there is A35.

 

[Robbie]

Quite amazing how high the revs are at which the maximum torque is generated. Perhaps they are going the Ferrari route.

 

[Rolf]

Some pics of the new engine. Its quite the powerhouse. It has a huge turbocharger as well.

 

[Centurion]

We need a power and torque graph ASAP.

 

[JLBM]

I must say, Mercedes seem to be leading in the engine tech department after trailing BMW for 15 years or so.

BMW is there, where it was 10 years ago. They need another Nocken-Paul.

Saw my second A35 AMG 4Matic on the road. The first one was yellow, but I couldn't get shots of it since I was driving and it came out of nowhere on the other side of the road. The blue W177 A35 AMG 4Matic below is so gorgeous. I just feel that the 18" AMG wheels are 1" too small. My winter wheels are 19" RIAL M10s and they fill up the wheel housings so much better.

Can't afford an A45 AMG? Is the A35 AMG "too underpowered" for you? Then this is your solution!


MKChip-DKR Bumps Up Mercedes-AMG A35 Slightly With Stage 1 Upgrade

Until the full-blown 45 versions come out, the AMG A35 is the top dog in the new A-Class family.

Naturally, the “baby Merc-AMG” has already attracted the interest of tuners. MKChip-DKR, for one, has developed a new software that increases output to 341 PS (336 hp / 251 kW) and 505 Nm (372 lb-ft) of torque.

By extracting a relatively modest 35 PS (35 hp / 26 kW) and 105 Nm (77 lb-ft) more from the 2.0-liter turbocharged four-cylinder, the German tuner claims that the 100-200 km/h (62-124 mph) acceleration has been improved by 1.6 seconds.
McChip can also increase the top speed to 285 km/h (177 mph) for an extra buck. Furthermore, Stage 1 upgrades are available for other versions of the new-gen A-Class as well, like the A200, A220 and A250 models.

Even in stock form, the new A35 is pretty nifty despite being the weakest AMG model in Merc’s catalogue. The 0-100 km/h (0-62 mph) sprint takes 4.7 seconds and top speed is electronically limited to 250 km/h (155 mph), while its compact proportions, similar performance and all-wheel drive system put it in the same class as the Volkswagen Golf R and all-new BMW M135i, both pretty serious pieces of kit.

Mercedes, though, is getting ready to upstage all of thjem with the new A45. The future Audi RS3 Sportback challenger will become the most powerful production hot hatch in the world, with reports claiming that the A45 S will have as much as 421 PS (415 hp / 310 kW) in “S” guise. Considering that the previous-gen A45 hit 100 km/h (62 mph) in 4.2 seconds with “only” 381 PS (376 hp / 280 kW) at its disposal, it’s not hard to figure out that the new one might drop to somewhere around 3.5 to 3.7. Which, any way you slice it, is truly mega.

Its quite an engine.

 

[Rolf]

Its quite an engine.

The torque curve of the new engine is not as flat of the older engine but it has higher torque throughout the rev range except perhaps from 1000 to 3000rpm when its lower torque than the old engine.

In fact it is lower from 2000 to 3000 rpm.

Saw this just now. The new BMW 1-Series with M Body Kit - and appropriately parked directly behind it was its current rival - the new Mercedes-Benz A-Class AMG Line (and behind it the old F20 1er).

Here are my snapshots of both cars so you can compare them visually.

 

[Robbie]

Great real world pics. The 1 looks so much bigger from the rear doors to the back, and also taller.
