Much of BMW's U.S. market lineup is making the switch to a 2011 model year designation early this spring with the highlight being a new version of the 3.0-liter inline-six cylinder engine dubbed N55. The N55 has the same 300 horsepower and 300 pound-feet of torque as the previous N54. However, the previous twin turbocharger configuration is now replaced by a single twin scroll turbocharger. The twin scroll has two inlets letting the exhaust gases into the turbine. The inlets are spaced to allow
To many people, Audi is replacing BMW as the go-to yuppie-mobile of choice. For one thing, Walter de'Silva's designs are almost universally lauded (Q7 notwithstanding) whereas the new crop of Bangled Bimmers are... controversial to put it as nicely as humanly possible. But it's not just down to looks and interior -- it can't be.
When the BMW 335i arrived in 2007, tuners jumped at the chance to boost the boosted 3.0-liter inline-six. After a few ECU tweaks, the new 3 series was putting out an additional 70-80 hp and a commensurate increase in torque, and once the 135i and 535i arrived, the market grew accordingly.
BMW's N54 engine has won the International Engine of the Year award for the past two straight years. It has also been listed as one of Ward's 10 Best Engines during the same period. The engine produces 306 hp and 295 ft-lbs of torque in a 3.0L inline six package thanks to the use of twin Mitsubishi turbochargers and direct injection. The N54's quick response and smooth torque curve has been an attraction for many enthusiasts, including myself - I call my Montego Blue coupe the turbo Cookie Monst
For those fond of delving deep into E90 minutiae, these are the best shots yet showing off the subtle changes coming to the BMW 3-series. For the rest of us, the tweaks are largely inconsequential. World Car Fans has unearthed some of the clearest shots yet, and the change that most people will notice are the taillamps, which look to get a slightly different shape. It even appears that the cutlines between the taillamp pieces on the trunklid won't line up with the rest of the cluster mounted in
Dinan, renowned tuners of all things from the propeller people, have finally decided to offer an ECU upgrade for owners of BMW's delectable 335i. The reflashed upgrade necessitates the installation of either BMW's or Dinan's oil cooler, but once the Bimmer's brain is reprogrammed, throttle response is sharpened, the top-speed governor is removed and power levels jump to 384 hp at 5,700 rpm and a kidney pummeling 421 lb.-ft. of torque at 4,300 rpm.
