| 2011 BMW 335i gets a Single Turbo Engine and a facelift
Quote:
BMW has officially released the details and photos of the refreshed 3 Series coupe and convertible.
As we await the next 3 Series sedan that is expected to be unveiled some time next year, we can enjoy a refreshed 3 Series coupe and convertible. The coupe and convertible get a refreshed face for the 2011 model year. This includes slightly tweaked headlights, a larger grille and a revised lower fascia. The rear end gets slightly revised taillights.
The 328i features 230 horsepower while the 335i has 300 horsepower and is the first inline-6 equipped with a single twin-scroll turbocharger, BMW's Valvetronic throttle-less intake technology, High Precision direct fuel injection, and all-aluminum construction.
The 335i's new inline-6 engine displaces 3.0-liters and develops maximum output of 300 hp at 5,800 rpm, with peak torque of 300 lb-ft available all the way from 1,200-5,000 rpm. Redline is 7,000 rpm. This is the same level of performance as the previous 3.0-liter twin-turbo inline-6 but with the innovation of twin-scroll technology and the integration of Valvetronic, this new engine is even more fuel efficient.
|  
The Current Twin-Turbo 335i:
Max. Power 306.2 PS (302.0 bhp) (225.2 kW)
@ 5800 rpm
Maximum torque 400.0 Nm (295 ft·lb) (40.8 kgm)
@ 1300-5000 rpm

got a dumb face.
Also BMW is doing factory "single turbo mod" for you like Supras and Skylines. LOL.

Nothing spectacular in terms of the engine or design. Why don't they just make a 3.5L block with DI only and avoid the turbo altogether? They could probably get 320+ HP with that alone...

I hope the LED tails will fit on my e92 but the front bumper looks awful.

Actually the twin scroll (which means basically 2 chambers on the boosted side of the turbo) is what is significant, it saves weight and improves spool up speed. Not to mention remove a few wastegates etc.
BTW It has always been a M54 3L block has never been a 3.5L block. Quote:

Well maybe weight is that important. However, it still is basically on par with the 2005 released Toyota 2GR-FSE in terms of power and fuel efficiency. However, that engine does not have a turbo and is plain DI.
2009 335i sedan: 11.9/7.7 according to http://www.bmw.ca/ca/en/newvehicles/...ical_data.html
Subtract 1 L/100km according to http://carscoop.blogspot.com/2010/01...nvertible.html for the 2011 model.
= 10.9 / 6.7
A GS 350 with a bit more power and a bit less torque (2007+):
10.9/7.4 according to http://www.lexus.ca/lexus/experience...1KST&year=2010
So I still stand by saying nothing spectacular, especially considering the stress the turbo adds on the engine (and squeezes out that extra MPG on the highway as a result). Now if it was a large jump in power and the same MPG I would agree it would be a good upgrade.

The front is kind of swollen because it has to meet the latest pedestrian safety regulations. It's affecting most new cars.

3.0L is the magic number for that size of car for insurance reasons in other countries.
the single turbo should bring more efficiency and bump fuel economy up.
ppl with supras switch to a single turbo setup because they are upgrading to a single way more efficient turbo. though in theory, a twin/sequential turbo setup is suppose to spool up better, but this is based on all turbo's being the same performance. Quote:

No one saying it is spectacular, the N55 is an improvement over previous N54... Maximum torque at certain RPM is just one data point and honestly a rather useless comparison for real life usage. The torque curve is what has been improved here, where the twin scroll turbo shines. Along with manufacturing and cost efficiencies. Actually a better more useful comparison will be a topograph with all the gearing / shift points information for all the transmissions.
Notice that N55 is mated with the new DCT. Transmission and weight pays a large part of the fuel efficiency in the numbers you are quoting. If you want to skew the number further you can include cars like Evora which is much lighter than any cars Toyota makes.
As for the look, it is minor aerodynamic improvements (more closed vents to improve Cd). I think when the 3er came out it already conform to pedestrian safety (it was enacted in the EU around 04). Remember the 3er is already in its last few years, so it will look odd when it has bits of F01's design theme grafted on it. Quote:
