One of 1,815 Z4 M Coupes made for North America, and fewer than 100 that are supercharged! I'm selling my highly upgraded Z4 M Coupe only because a new car needs the space in the garage. It will be very tough to see it go--I've put a lot into it, both in personal work and cash. It has been carefully maintained under my ownership (California car and always garaged, of course)--and I have been the longest owner in both time and milage (about 4 years, and ~26,000 miles). CLEAN TITLE, no accidents of any kind.

The car has 51,000 miles and a long life ahead of it. There are a few isolated cosmetic damages; the previous owner scuffed the front right of the bumper on a curb, but it is now better-protected by metal skid plates I installed on the bottom of the bumper. The paint is in good condition--no dents or major scratches aside from the bumper--though there are minor imperfections. The interior is in great condition overall, especially the leather throughout, except for some scratches on the driver's side door sill. I have always driven and treated the car with great care for its longevity: minimal engine load until both oil and coolant are fully warmed up (which takes longer with this car than many), carefully avoid potholes and rough roads, used a sun shade when parked to avoid UV damage to the interior, personally cleaned and conditioned the leather, etc etc...

The car drives incredibly. Even before modifications, this was one of BMW's fastest and lightest production cars. With the stage-2 supercharger kit, it attains supercar-like performance and high overall refinement for an unbelievable value (at least now that I've spent the money and time tuning the supercharger for you!). Maintenance is completely up to date with a full records history--most importantly, the expensive Inspection II service has been recently performed, which includes a painstaking manual valve adjustment. I personally found the best BMW dealer tech on the peninsula and gave him a cash tip to ensure his work during this important job was of utmost quality. If you buy a lower-milage Z4 M, you'll be looking at well over $2,000 in the near future for this service.
Test drives can only be offered to serious buyers. This car is extremely powerful, and while safe and capable (side air bags, stability & traction control, astounding brakes), it needs to be treated with respect.

Headline features / improvements:

- ESS VT2-500 Supercharger Kit--"stage 2", including a large and extremely effective intercooler. Rated 500 BHP and dyno-tested at corresponding RWHP. Cost over $15,000 with professional installation, testing, and tuning.
- High-tech digital gauge system integrated behind the rear-view mirror glass. Invisible with the car off, seen as an overlay on the image in the mirror when the car is running. Air/Fuel ratio and Boost gauges are present on the left and right, as is a GPS-assisted Radar/Laser/Red Light Camera detector. Over $3,500 to purchase and install. I am going to miss this on my new car! This is a really unique feature, but I don't have photos right now (check out radar-mirror.com)
- BMW European exhaust manifold. improves performance beyond the standard supercharger kit, and produces a stunning exhaust note. Carefully installed personally (an entire day's work). Over $1,000 in parts.
- LoJack Vehicle Recovery system.
- Adjustable camber plates in front and lower suspension arms in the rear from the best suspension part manufacturers available for the Z4M.
- Full set of expanded-width Michelin Pilot Super Sport tires (considered by many to be the best performance tires available). Plenty of tread left (more than 50%).
- Brand new front brakes, less than 1,000 miles on them. The front brakes are about 4x more expensive than the rear, and lasted the whole life of the car, so they will not have to be redone until after 100,000 miles.
- High quality window tint on the side and rear glass (no bubbles, looks stock but keeps the heat out!
- Numerous dealership-installed replacements, including a new VANOS system (!!! normally $5k+ replacement and the major problem area with factory S54), BMW OEM windshield (original cracked by a rock), navigation system screen, interior trim pieces, and shift knob.
- Extensive, detailed service history and full original manual (leather binder).
- Tons of extras like BMW perfect-fit sun visor, touch up paint (haven't needed to use it yet), short shift kit, new set of spark plugs (though the currently installed ones will last at least 30k more), the original intake parts from before the supercharger and original US exhaust headers, etc.
- Bavarian Soundwerks Speaker Upgrade
- Navigation system with Bluetooth connectivity (part of the premium package)
- Frequent changes of all fluids, including half the factory required milage on engine oil; supercharger oil, differential and transmission oil, brake fluid. Always top-tier fuel manufacturers.
- Much, much more!


More details on the powertrain and driving characteristics:

- Supercharger is a centrifugal type, basically a belt-and-gear-driven turbocharger compressor wheel. Maximum boost is about 7-8PSI, which builds roughly linearly throughout the RPM band.
- In addition to a large intercooler, the oil cooler is tripled in size and keeps oil temperatures slightly lower than stock, even under load.
- The S54 motor is a 3.2L inline-6 with a 7,800RPM redline; at the time of its launch it had the highest naturally aspirated output per liter (333HP from 3.2L) of any BMW engine in history, and remains one of very few engines to break 100HP / Liter without forced induction.
- The motor's natural tendency to make the greatest power at higher RPM combines with the centrifugal supercharger's own boost profile to produce a truly exceptional surge of power from 5,000RPM-7,500RPM.
- S54's have individual throttle valves directly in front of the intake valves for each cylinder, which provides amazing throttle response. Combined with the always-on supercharger that has boost at the ready while driving, at 2,000RPM or above the response is absolutely immediate.

BMW recalls over 76k 2012-2014 models over brake failure

Sat, 28 Sep 2013

Bimmerfest is reporting that BMW has notified the National Highway Traffic Safety Administration of its intention to voluntarily recall more than 75,000 3 Series, 5 Series, X1, X3 and Z4 models due to a possible loss of power brake assist that could result in the vehicles failing to stop. The recall affects 2012-2014 models equipped with either the N20 or N26 engine produced from May 2012 to August 2013. Until recall repairs have been performed, BMW dealers will discontinue selling or delivering any affected vehicles in their inventories.
The problem has been traced to restricted oil supply from the intake camshaft to the brake vacuum pump, which may cause the brake vacuum pump to fail, resulting in a loss of power brake assist. While the hydraulic brakes will still function, the driver must much apply greater pedal pressure and the distance required to stop the vehicle will increase.
BMW has reported three minor accidents with no confirmed injuries. According to Bimmerfest, drivers who encounter a braking problem should "pull the emergency brake and apply as much brake pedal pressure as possible. If your BMW has an electronic parking brake pull up and hold the switch to engage the brake." Drivers should then park in a safe location and contact BMW Roadside Assistance.

BMW i5 could be a new kind of i PHEV

Tue, Apr 14 2015

Just this month BMW North America CEO Ludwig Willisch made a point of saying "Not any time soon" to AutoblogGreen's question about the arrival of a BMW i5 - and that came after he clarified, in case we didn't know it, that no such model exists. But the rumors of its eventual appearance were swelled again by a report in Autobild that sticks more details and numbers on what could be the next offering in for the i brand. In February, Car magazine laid the i5 out as having a 245-horsepower four-cylinder engine in front, assisted by a 204-hp e-motor in the bow and a 90-hp e-motor in the stern, for about 544 total horsepower. Autobild claims the gas engine will have 218 hp, the front e-motor will have 150 hp and the rear will have 272 hp, for roughly 640 total horsepower. Where the two reports agree is that it - maybe called i5, maybe i7 - will be based on the China-market long-wheelbase 5 Series platform, it will incorporate cues from both the 7 Series and 6 Series Gran Coupe, and it will not be cheap: 100,000 euros ($105,686 US) is the estimate. The i8 starts at 130,000 euros in Germany. Weight for the i5 is figured to be around 3,300 pounds. Green Car Reports says what's important about the i5's drivetrain is that it's being maximized for electric running. Its evolution of the company's eDrive mechanicals will crank the ICE over only above 36 miles per hour, and even then, only in cases of "maximum power demand." Electric-only driving would offer a range of 78 miles, company officials suggesting that it could remain in that mode for "fully two-thirds of its usage cycle." Whenever a vehicle like this arrives, that is, which Autobild says could be in 2019.

What would you drive in 1985?

Wed, May 6 2020

Bereft of live baseball games to watch, I've turned to the good ship YouTube to watch classic games. While watching the 1985 American League Championship Series last night, several of the broadcast's commercials made its way into the original VHS recording, including those for cars. "Only 8.8% financing on a 1985 Ford Tempo!" What a deal! That got me thinking: what would I drive in 1985?  It sure wouldn't be a Tempo. Or an IROC-Z, for that matter, despite what my Photoshopped 1980s self would indicate in the picture above. I posed this question to my fellow Autobloggists. Only one could actually drive back then, I was only 2 and a few editors weren't even close to being born. Here are our choices, which were simply made with the edict of "Come on, man, be realistic."  West Coast Editor James Riswick: OK, I started this, I'll go first. I like coupes today, so I'm pretty sure I'd drive one back then. I definitely don't see myself driving some badge-engineered GM thing from 1985, and although a Honda Prelude has a certain appeal, I must admit that something European would likely be in order. A BMW maybe? No, I'm too much a contrarian for that. The answer is therefore a 1985 Saab 900 Turbo 3-Door, which is not only a coupe but a hatchback, too. If I could scrounge up enough Reagan-era bucks for the ultra-cool SPG model, that would be rad. The 900 Turbo pictured, which was for auction on Bring a Trailer a few years ago, came with plum-colored Bokhara Red, and you're damn sure I would've had me one of those. Nevermind 1985, I'd probably drive this thing today.   Associate Editor Byron Hurd: I'm going to go with the 1985.5 Ford Mustang SVO, AKA the turbocharged Fox Body that everybody remembers but nobody drives. The mid-year update to the SVO bumped the power up from 175 ponies (yeah, yeah) to 205, making it almost as powerful (on paper, anyway) as the V8-powered GT models offered in the same time frame. I chose this particular car because it's a bit of a time capsule and, simultaneously, a reminder that all things are cyclical. Here we are, 35 years later, and 2.3-liter turbocharged Mustangs are a thing again. Who would have guessed?
