I would be interested to see the dyno curves for this engine as I imagine it has a pretty large turbocharger on it. I realize with DI they can run a higher compression and all the internals forged should be able to handle a fair bit of abuse but I would expect some turbo lag for a 2.0L at this power level.
BMW's new turbo 2.0L 4-cylinder while not making near the same power is a pretty impressive engine in itself scooting the heavy 3-series around very quickly as it's nice to see what high end manufacturers can do with this engine configuration. We've seen it for years from the Japanese car companies but those engines (even the 4G63 or SR20DET) were always built at a price point whereas BMW and MB can incorporate higher quality internal parts and technology.

your reading comprehension is really low.. Where did I mention the FUNCTIONAL aspect/significance of CF interior pieces? It's all in context of interior QUALITY Please show me fake CF trim that looks at least half decent. People that know will notice a fake by looking trough the closed window lol and CF trim in MB is just a PART of it. Even by looking at the pictures I can tell that material quality of the rest of the interior is better than Mustang's. I ques you're that kind of a guy that would wear a fake gold chain and be happy because it's as shiny as real thing but 20x cheaper lol |

There's a difference between keeping out of boost and keeping out of enrichment (richer than lambda=1). At a given torque level, a small engine at higher load is more fuel efficient than a bigger engine at low load, as long as the smaller engine doesn't have to run pig rich to prevent knock or prevent the cat from burning up. Good examples of this are the Fiat MultiAir 1.4T engine now in the Abarth, and the current BMW valvetronic + turbo engines. They use dethrottling extensively and have a broad area running lambda=1. VW also has an engine family with a water-cooled exhaust manifold now. Quote:
That's why you'll notice expensive small displacement turbo engines (BMW, VW/Audi) tend to have a smaller gap between its real-world and rated fuel economy than cheaper ones (Nissan Juke engine for example, Chevy Sonic 1.4). They don't have to dump in fuel as much, so they take advantage of the dethrottling aspect better. Last edited by arghx7; 04-06-2013 at 10:00 AM. |

I object, I plan to track my R this year with the sole purpose to destroy the All seasons it came with!
HAHA,, but I get what you meant CJ |

I don't think you need to object.. would you spend an extra $10k on a car with a slightly glitzier interior and way more lag on the street just for the occasional track day? Don't forget the mandatory flappy-paddle gearbox..

Back on topic, it does seem that Mercedes is mimicking the "sucked in gut" look of the BMW 1 series to make it look more svelte. |

I'd have to imagine that MB would tune this car like any other late-model twin-scroll turbo car... a plateau of torque from just off idle to the magic 5252.
Lag isn't really an issue anymore. |

Not really on subject, but Skylab, check out the APR website. A vagcom cable and 30 minutes of time and you get the same 2 stage stability control that the rest of the world gets. You get on, partially disabled, and off. It only takes a VAGCOM cable just as you mentioned sir. I think VW is funny. They build this car capable of taking on all comers in europe then they just program away the hard nosed things for us lazy Americans. I think it is funny that the program for the 2 stage stability control is already in the computer, you just need to change a few numbers and it works just as if it were OEM.

.. but the "specs" released so far suggest otherwise: 355 BHP @ 6000 RPM 332 lb-ft @ 2250-5000 RPM The EVO X has a twin-scroll and is what I'd consider a somewhat modern engine, and it doesn't reach full boost until 3200rpm. All of the twin-scroll setups I've seen with flat torque curves that come on at low RPM usually aren't good for horsepower bragging (see MCS, Focus ST, VWs/Audis). I the dynos actually support this claim, I may have to about-face my opinion on this car. |

Such as technology progression, of twin turbo, twin scroll, sequential turbo, and Porsches variable ..?/ turbo and antilag (i know thats not street viable, but you get my idea). I want to see reviews before coming to a conclusion |

The question is, does it feel laggy in the actual vehicle? That's going to depend a lot on the throttle and shift mapping. I wonder if it uses a Titanium Aluminide turbine wheel. This AMG website has a little more info: http://www.mercedes-amg.com/engineer...?section=20l4c details from that site: -- closed deck aluminum block with various strengthening measures -- 140bar max combustion pressure -- low friction coating (what AMG has been calling "nanoslide" for a while) -- forged crank, rod, pistons -- extra crankcase ventilation/oil separation passages -- sodium-filled exhaust valves -- roller finger followers with hydraulic lash adjusters -- dual variable cam phasers (AVCS) -- air-to-water intercooler, 1.8 bar boost -- looks like an oil cooler might be integrated into the low temperature cooling circuit -- 200bar max fuel injection pressure w/ center-mounted piezo injector for spray-guided combustion -- 8.6:1 compression ratio fuel economy strategies -- smart alternator control -- start/stop -- demand-controlled oil pump -- meets Euro 6 emission standard -- probably 2 cats total, although the pictures only show 1 Last edited by arghx7; 04-07-2013 at 01:03 PM. |

I want one...
I thought I was set on a GTR for my next car. But now I am thinking about this CLA AMG45 or GT3 RS ( I live a mile away from a Porsche dealership) Now all I need to do is get promoted to Chief (E7) and as always get my wifes permission . |

Nice find!
Truthfully, if you romp on a car in gear below 2000rpm you're doing it all wrong. That's what Macks are for. I just sold my 2010 Evo X SE in November. Good power delivery for an OEM tune(we all know what happens with tuning that engine), but not as nice as what we're seeing for the MB. |

I find this special edition evo to be a pretty good deal. I was considering an Evo X before my Brz, but mitsubishi abandoned modernizing the 4b11 with direct injection and lightening the car.

GTR - $100,000 GT3 RS - $190,000 CLA45 - $50,000 If you can afford the other 2, why even think about this one? Seems like a big step down. |

Remember... To want is one thing (but I am speaking of used)... It would be nice if i could afford new though.
The car you drive is a big part of your lifestyle so which ever way I go it's gonna be a step in a new direction. I still have 4 kids which is a big factor. Last edited by punchjamesarnol; 04-07-2013 at 09:58 PM. |

Yeah, I got to browse a bit.. but watching a 10mo child makes posting a low priority.
How much attention do you normally crave? I'm probably not worth stalking if you need it constantly.. you'll be disappointed. I haven't had a stalker in a while (that I know of), and I'm flattered... but for someone who claims my posts annoy him, you sure seem upset that I haven't posted more.. http://i.imgur.com/z4q4NDC.gif |

I would have stalked you CJ, but I am too busy camping out in HTBS bushes.
