      Renntech is branching out to other markets from their traditional Mercedes tuning and they have several ECU tunes now available for BMW vehicles. The Renntech 335 diesel tune puts down an impressive 311 horsepower to the wheels along with a tremendous 432 wheel torque. The ECU has to be sent in for the flash unless one is local. A 24 month warranty is also included in the $1100 price. This tune should be applicable to the X5 diesel as well in the United States.

      Well here it is, the new 2012 4 door F30 3 series. Not really all that much different externally with BMW playing it extremely safe. The styling envelope is not being pushed with the 3 taking cues from the F10 5 series for the headlights and the rear taillight design being as benign as possible. The interior is also a very minor update on the E90 with the BMW switchgear and gear lever that we have all grown accustomed to.

      You may remember that AutoExpress drag raced the 1M against the DSG RS3 a few months back. In that comparison, the Audi won by virtue of its dual clutch transmission and all wheel drive launch although the 1M had the higher trap speed. This time both cars are taken around a road course and the 1M just flat out crushes the Audi by almost 2 seconds on what is a fairly short track. The driver mentions the Audi is heavier and more of a car for beginners with understeer versus the 1M which is more nimble and often requires the throttle to correct the tail stepping out. Check out the video below.

      A N55 355i Owner was kind enough to stop by last week for some testing of a prototype unit of the cp-e N55 downpipe. The day went perfectly for such testing. The part was designed and built completely from computer data, without any fabrication on the car. The part was already ready without being in any vehicle prior. This was a true testament to doing CAD development in the most effecient way possible. Fitment was dead on, lining up with brackets, flanges and sensors flawlessly. Performance was to our satisfaction as well. Dyno charts below.

      So, what is with all this talk about the Chinese buying up luxury cars left and right? Turns out China, just like everyone else, has cars sitting on dealer lots with dealers willing to discount BMW's up to 19% as reported by Businessweek. Growth is definitely slowing down for the luxury automakers in China but BMW believes growth is sustainable. A Chinese BMW representative stated, It is predictable that the Chinese car market will keep growing at a comparatively lower rate. BMW has maintained a strong and sustainable growth. May we have some special editions in the USA now BMW?

      All chrome paint jobs are tacky. Yes, tacky even if an OEM does it. However, that does not mean we do not want to see it. BMW for whatever reason decided to create a Chrome Bullet M3 with chrome paint obviously as well as M color accents. BMW uploaded the photos of the car to their M Facebook page without much supplementary info but from what we can gather this is just a one off showcar. Cool to see, but BMW's chrome shadow paint job on the E46 M3 concept was just plain better than this as it wasn't so ostentatious, looked great, and actually could be pulled off in public.

      Insideline recently tested the new Z4 with the new N20 turbo 4 cylinder motor that is vastly underrated. The Z4 used was a manual and we would not be surprised if the auto produced better numbers. Insideline did not state where this test was done but they frequently use Fontana which is a notoriously slow strip. It is not far out of line to suggest this vehicle can hit high 13's in the 1/4 mile stock in better weather at a better track. That puts it roughly on par with a USA E36 M3 in a straight line. The Z4 actually happens to put more power down to the wheels than the US E36 M3 which should put the new N20 in perspective.

      OE Tuning has tuned the new BMW 1M Coupe. On a dynojet in STD correction on 93 octane the 1M baselined 325 wheel horsepower. The car hit 375 wheel horsepower after the tune also on 93 octane fuel as OE Tuning sttated, very impressive. The dynograph below however shows a baseline of 332 rear wheel horsepower and 383 rear wheel horsepower after the dyno tune. All dyno pulls were done in 4th gear.

      The E46 M3 SMG (sequential manual gearbox) is basically the exact same thing as the manual transmission except with a hydraulically actuated shifting mechanism. The hydraulic pump can fail and VS Motorsports states the replacement cost is $2500 (a bit high) from BMW. Regardless, many people have wondered how much it would cost to simply switch an SMG to manual as well as how difficult it would be. VS Motorsports answers the latter below with an SMG to manual swap.

      Here is yet another severely underrated BMW turbo motor. BMW rates the Z4 Sdrive28i at 240 horsepower at the crank. Insideline tested the car on a dynojet and hit 233 horsepower to the wheels. To put things in perspective, BMW rates the motor the N20 replace, the N52 6 cylinder, higher than the N20 at 272 horsepower in its highest output form yet it dyno's less to wheels hitting the 199 rear wheel horsepower range. So not only is the N20 rated lower, it dyno's higher. BMW is hideously underrating their turbo motors.

      M3 vs. M5 battles are a ton of fun. Usually because M5 owners have their heads so far up... in the clouds. They tend to think an M3 is no match for an M5 and this is fun to mess with especially with a modified M3. An M5 can be modified as well of course and this video shows how much stronger the top end on a naturally aspirated tuned S85 is (exhaust, scoops, filters, tune) vs. a naturally aspirated tuned S65. Top end racing is where that V10 shines. Time for those blowers on the M3's fellas.

      People are going to debate if this car is still a BMW but from what we understand this is still an E30 chassis with a manual transmission and a heavily modified S38 I6. The 3.7 liter motor features Pauter rods, Arias pistons, 264 degree cams, full methanol, 6 1200 cc injector, 6 1000 cc injectors, and a custom T66 turbo. Power is estimated in the 1300 horsepower range. The body has been modified with fiberglass front fenders and a hood. It has run a best of 7.69@184 miles per hour. We do not know what to say other than congratulations to Budler Motorsports.

      Well, this isn't much of a surprise as BMW pretty much had everything wrapped up at the previous race. BMW managed to finish 3rd and 9th at the 1000 mile Petit Le Mans which was good enough to get their second straight overall ALMS GT title. It was a dominating season for BMW which had 7 consecutive poles at one point as well having started the season with a string of victories. How do you like the BMW V8 in the M3 now Porsche?

      The new F32 4 series is coming (what we all remember as the old 3 series coupe) and German outlet AutoZeitung has provided their rendering. Nothing shocking, simply looks like a downsized 5 series which is what all the spyphotos have been leading us to believe anyway. The F30 3 series is set to be revealed in mid-October and it is possible the 4 will be revealed with it. Regardless, expect official photos soon but this renderings should not be far off from the real thing.

      It is nice to see BMW at least gave the 1M a little more in the tune over a standard N54. They obviously could have put out much more if they wanted to. 346 wheel horsepower in STD correction is pretty darn good for with an intake. That is basically M3 power right there. The car is rated at 335 crank so when a vehicle is putting out more to the wheels than it is rated at the motor that is definitely what we call underrated. This leads us to believe the reason the 1M did not get the DCT transmission is it would have stepped all over the M3's toes.
