2007 BMW 335i Coupe Turbo

The 335i, 328i, 330i, and 325i all have 3.0-liter inline-sixes. The 328i is a coupe with a 230-horsepower six that falls between the 255-horse 330i and 215-horse 325i, which are both four-door sedans. Deep breath. The 335i, then, is a twin-turbocharged direct-injection 3.0 that makes 75 percent of the expected power of next year's M3 V-8.

There's linearity to BMW horsepower numbers, from the M5/M6's 500-horse V-10 to a 400-horse, 4.0-liter V-8 in the 2008 M3 to 300 horses for this handsome new coupe. This is something different for BMW: Its first-but not last-gas direct-injection engine, with piezo injectors feeding the combustion chambers for a more equal distribution of fuel. The twin turbos act in parallel, each boosting three cylinders. They're inside an all-aluminum block with cast-iron liners that cut cylinder bore by 1.0 mm versus the naturally aspirated 3.0-liter. The world's first twin-turbo inline-six, according to the Bavarian automaker, is its future in providing efficient high performance.

Like all good sport coupes and all good BMWs, the 335i is greater than the sum of its parts: full of unquantifiable qualities, an embarrassment for the car critic who's trying to be critical. It's like butter, that twin-turbo six, and the turbo lag you might expect melts into smooth acceleration. But there's still a power surge to tell you turbos are in place hard and early. Its exhaust gives off a satisfying rasp that'll quickly become identified with this specific engine to sharp-eared juvenile enthusiasts. Three-hundred pound-feet of torque kicks in from 1400 to 5000 rpm, making it a quick-launching Euro coupe that'll feel at home in the American V-8 environment.

The 335i's suspension offers more compliance than one might expect, although springs and shocks are stiffer than any 3 Series sedan's. North American 335i buyers get as standard the Euro-spec Sport Package suspension, with a delete option. For the U.S., "Sport Package" means 18-inch wheels with 225/40R18F front/225/35R18R rear tires, upgraded from the standard 225/45R17 H-rated all-seasons. Both sizes are no-spare run-flats, and their stiff sidewalls allowed German engineers to remain on the supple side of the ride and handling equation. It works as well-or better than-it's always worked for the 3 Series. While our drive was limited to mostly tabletop roads in the Austrian Alps, there was enough rough blacktop to learn that Americans who are used to substandard pavement will be comfortable in this car.

1972 Bmw 2002 Tii

1968. Richard Nixon was elected president. Fighting raged in Vietnam with no end in sight. America watched "Hawaii Five-O," "Mayberry RFD," and "Here's Lucy" on an ever increasing number of color television sets. Robert Kennedy and Martin Luther King Jr. were assassinated. "Oliver" won the Oscar for Best Picture. Otis Redding was sittin' on the dock of the bay. And BMW introduced the 2002 in the United States.


Launched in Europe in late 1966 by a company still struggling to right itself after WWII, the 2002 summarily defined the modern compact sport sedan (even though it had only two doors) and saved BMW by doing so. Bayerische Motoren Werke was anything but a high-volume carmaker back then, and although it had a few successes to its credit, it appeared destined to remain a second- or third-tier player behind German giants like Volkswagen and Mercedes.

The 2002 changed all that. It imbued the everyday car with a measure of sportiness and sophistication, demonstrated that performance means more than going fast in a straight line, and moved BMW a notch up the automaker food chain. The 2002's combination of sports-car handling, room for four, an airy greenhouse, and a large trunk, plus BMW's growing reputation for engineering and high-quality construction, came together in a car that caught the attention of enthusiasts the world over who didn't want a four-door, yet needed something more than a rickety British two-seater. It made a great economy car, a great race car, and served many needs in between. BMW sold more than 860,000 2002s worldwide before it was replaced in 1977 by what was then-and is today-called the 3 Series.

BMW is well aware of the 2002's status as a corporate, automotive, and cult icon. And, like most German carmakers, it does a good job of nurturing its heritage. The division that provides technical, parts, and service support is called Mobile Tradition. In early 2005, the folks at Mobile Tradition realized they stocked or could supply about 90 percent of the parts needed to not only maintain or restore a 2002, but to build a virtually brand-new one. So they did.

A "Glass Workshop" was constructed in the shadow of BMW's multicylindrical world headquarters in Munich. The project, based on an original 1970s body shell, was spearheaded by Klaus Kutscher, head of the BMW Mobile Tradition workshop, and master mechanic Arthur Herrmann (see sidebar). The decision to craft the car as a tii model was made early on. The fuel-injected tii, sold in the U.S. from 1972 to 1974 (all prior and later 2002s employed carburetors, still common in those days) was intended to comply with emissions requirements and the onset of unleaded fuel. But the benefit was much more power and increased driveability, making the tii the best-performing and most highly sought model among all 2002s.


The project took about 11 months, beginning in May 2005. The Mobile Tradition 2002 made its debut at the Techno Classica show-one of Europe's largest and most significant classic-car conventions-in Essen, Germany, in April 2006. It traveled to America four months later, stopping in Northern California during the Monterey/Pebble Beach weekend in August. And that's where we pirated it off for a day of photography and hard driving through some of the Peninsula's best roads.

In the metal, this new/old 2002 captivates. Looking period-correct in brilliant Inca Orange-the same color as Motor Trend's 2002 tii test car featured in our January 1972 issue-Mobile Tradition's toy is downright cuddly. The assembly workmanship and finish are first-rate. It all looks, feels, and even smells factory original (if a bit better), yet it's not overrestored. All the cues are 1970s-right. Chrome and satin-finished trim, narrow alloy wheels, hand-cranked windows and metal sunroof, businesslike black instrument panel, dished three-spoke steering wheel, etc. The final touch: "Cocoa" floormats.

2007 BMW X3 3.0si

The "si" is a meaningful addition to the badge, signifying a new, stronger engine, but there's more to the 2007 BMW X3 than a power upgrade. Fresh styling throughout, an available six-speed automatic, a more capable chassis, and additional content enhance this already appealing vehicle.

The BMW X3's freshened visual athleticism is technically supported by a more sophisticated version of BMW's standard xDrive. Quicker in response to traction issues, it also offers, for the first time in a BMW sport/ute, Dynamic Traction Control that allows the driver to choose a higher threshold of wheelslip before the electronics kick in. A longer push of the button deactivates stability controls completely except when the system detects wheelspin--not difficult to achieve with the brisk throttle response from the 260-horse inline-six.

Its 225 pound-feet of torque peaks at a low 2500 rpm, helping the 4100-pound BMW X3 claim 0 to 60 in 6.9 seconds with the six-speed manual and 7.1 seconds with the no-cost optional six-speed STEPTRONIC automatic. Any way you want to shift it, the BMW X3 is as rewarding as any of BMW's sport sedans.

2006 M Roadster

Offering more for less is a powerful selling tool. BMW hopes that approach will persuade prospective buyers of topless Teutonic tin to opt for its all-new BMW M Roadster instead of, say, that other roadster from Stuttgart. You know the one, the dream machine we said had "superb mid-engine balance, high cornering limits, scythelike steering," and a "wailing flat-six." But after a preview drive through southern Spain and a track session at the Circuito de Jerez in BMW's second-generation M Roadster, which packs 50 horsepower more than a Porsche Boxster S yet stickers for $3500 less, we can confidently tell you Porsche has legitimate cause for concern.

Like its predecessor, essentially a steroidal BMW Z3, the new BMW M Roadster is a high-protein version of the brand's Z convertible, in this case the face-lifted Z4--which, for 2006, receives freshened fascias and BMW's magnesium/aluminum N52 3.0-liter engine. Stylistically, the jump from Z to M is modest, but a roundel eye will spot the differences: two longitudinal humps in the aluminum hood; a sportier nose with larger air intakes; 18-inch double-spoke wheels wearing 225/45s in front and 255/40s in back; a more aggressive rear end with four chrome exhaust tips and a black diffuser; and, of course, the necessary M badges on the front three-quarter panels and the rear decklid. BMW prefers its M cars to appear "subtle and purposeful," and the roadster successfully conveys the credo.


That philosophy carries over inside, where the BMW M Roadster gets understated tweaks to jazz up the cockpit. The leather-wrapped steering wheel, adorned with the usual red-and-blue stitching, is thicker-rimmed than Buddy Holly's eyeglasses but looks appropriate and, more important, feels just right in the hands. Standard M sport seats, featuring embossed M logos on the head restraints, provide support in all the right places and wear soft leather upholstery, which also ornaments the door panels, handbrake, and shifter. The M's dominant dash decoration--a thick trim piece that sweeps from A-pillar to A-pillar--comes standard with a new brushed-aluminum surface, but also can be had dressed in carbon-fiber-look leather (a no-cost option) or walnut wood. Of course, the interior bit that really adds spice is the 9000-rpm tachometer scale, which, as in the BMW M3, sports a variable warning segment that adjusts the redline according to engine temp. This is useful because, once the 8000-rpm light turns off, the concert can begin.



Borrowed from the BMW M3, yet putting out three less horsepower due to more constrictive space for the exhaust, the BMW M Roadster's S54 inline-six mill not only produces 330 horsepower at 7900 rpm, but also plays mechanical notes so pleasing you'll want to put the sweet song of successive redline shifts on repeat mode. It's an engine that zings as much as it sings; and in a car that weighs over 200 pounds less than an BMW M3 coupe, its three-horse deficit means as much as a politician's promise. BMW claims the M Roadster can accelerate from 0 to 60 in 4.9 seconds, but the company is notoriously conservative with its figures. A 3383-pound M3 Competition Package we tested needed just 4.8, so the roadster is likely capable of around 4.7, or 0.3 quicker than a Boxster S. Top speed is limited to 155 mph.

2006 BMW 325xi Sports Wagon

The latest xDrive system (available in the 325, 330, 525, and 530 sedans, and the only drivetrain available in 325xi and 530xi Sports Wagons) is designed for a low center of gravity and optimal dynamics with minimal intervention and "extremely fast response times," BMW engineers say. (xDrive won't be available on the 7 Series until the all-new 2009 model.) The latest-generation xDrive, an update over what's in the X3 and X5 (there's no space for the SUV's transfer case in the cars), is integrated with the dynamic stability-control (DSC) system to provide a safety and handling benefit that'll satisfy most enthusiasts. The aluminum front axle is placed high up, through an opening in the oil pan, and the clutch can lock up completely when sensors detect the need for hard-core traction. Normal torque split is 40/60 front/rear, but the system can transfer all the torque to the front wheels. xDrive adds some 250 pounds.

How does it work? With good winter tires, like a rally champ on Arjeplog's ice circles and snow routes. You can mindlessly floor the throttle, and the DSC will work with xDrive to get you motivated efficiently, if not quickly. The DSC catches you if you turn in too fast. The hand of the Bavarian gods lets itself be known, although not as resolutely as an AWD Benz or Lexus.

Turn the DSC off, and you can play junior rally driver, sliding the car around an ice circle or drifting it on an icy road course, so long as you're prepared to pull it off a snow bank. xDrive is a worthwhile option on sedans if you're in schussing around in a far-northern climate, but enthusiasts facing more moderate weather will be happier with a set of winter tires and the lower weight and better balance of rear drive.

2007 BMW X5

If you've been clamoring for a crossover SUV with active steering and iDrive, it's finally here. The second generation of BMW's tall but sporty X5 launches in showrooms by the end of November. BMW says it's sold 580,000 X5s since it made its debut in 1999, with more than 240,000 of those staying here in the U.S., where it's built. Highlights of the new model include:



• 350-horsepower, 4.8-liter V-8 or 260-horsepower, 3.0-liter inline-six in the U.S. (other markets get an optional six-cylinder turbodiesel).
• Next-generation full-time xDrive all-wheel drive.
• Standard six-speed automatic with electronic gear selector.
• Active Steering optional.
• AdaptiveDrive, also an option, combines Active Roll Stabilization and Electronic Damping Control.
• Head-Up Display and standard runflat tires.
• New, larger interior with optional third-row seat (for seven passengers).
• Yes, iDrive control, with six programmable keys.

2007 BMW 335i Convertible

BMW could've topped its fourth-generation 3 Series convertible with handsomely tailored five-layer twill fabric like the one it just rolled out on the supercalafragalistic Rolls-Royce Phantom Drophead Coupe. But while the fabulocracy will write a check for a Flying Lady whatever her scarf is made of, the working rich are a whole lot fussier. For them only a tin-top will do these days.



Of course, BMW's breadwinner couldn't wear just any old tin-top. The company's design ethic doesn't include the flying wedges and chin-high beltlines that offer convertible-top designers a convenient place to pile the metal and glass out of sight. No, for the Roundel regulars, the junkin-the-trunk look would never do, and the existing three-piece-roof designs in use on competitors like the Volvo C70 and VW Eos were all deemed too bulky. So the company teamed with its German softtop collaborator Edscha AG to design what it claims is the slimmest-stacking top in the business.

Indeed, the new top not only disappears below a trunk that looks similar to the coupe's, it even preserves 7.4 of the 12.3 cubic feet of trunk space available when the top's up. That slimness exacts a slight aesthetic penalty, however. Two of the rods that guide the front section back over the middle remain in view when the top is closed. They're disguised as a couple of rubstrips running the length of the roof, but it's a less clean look than the competition offers.

The new top mechanism consumes very little rear-seat width, so shoulder and elbow room increases by 3.2 and 4.8 inches, and the side glass is 30 percent larger providing an airier view out. Sparse legroom will elicit grimaces from rear-seat riders over fivefoot-six, however, so vacationers will likely use the back seat for luggage. Toward that end, the rear seatback folds down to form a flat carpeted shelf and preserve the seat leather. BMW even offers a custom-fit bag to fill this space. There is a trunk pass-thru, but it's big enough only for golf clubs and skis, and it can be accessed with the seatback up and the center armrest portion removed. Loading luggage in the trunk with the top down is tricky. Customers opting for the $500 Comfort Access (keyless starting) package can use the key fob to raise the folded top out of the way and load the trunk, but the decklid pivots backward so the gear has to go in over the gunwales. It's far clumsier than the Volvo/Mercedes approach of raising the top stack with the trunk open normally.


Opening and closing the top takes just over 20 seconds and can be done from outside the car with the Comfort Access key fob. Operating the top with the car in motion is verboten for legal reasons (pivoting the trunklid back obscures the license plate). Other convertible highlights include an accessory windscreen that can be installed by one person from the driver's side of the car and leather upholstery treated with an infrared-reflective pigment that can lower the temperature of dark-colored seats by almost 30 degrees. The climate-control system also switches to a top-down mode that redistributes airflow and relies more on the outside-temp and sun sensors than the interior temperature monitors. Safety kit includes pop-up roll-bars and front-seat side airbags with head protection.

Despite the fact that the steel roof and its myriad motors and hydraulics weigh 308 pounds, the finished vehicle weighs just 440 pounds more than the coupe. Credit goes to weight-savers like plastic front fenders and more astute structural reinforcements using varying grades of steel. Torsional rigidity is up 50 percent, and indeed a 335i sport model sampled on smooth Arizona byways felt snare-drum tight, with no dashboard shakes and just an occasional high-frequency vibration following a bump impact with the top up or down. Using the wind blocker, heated seats, and climate-control system, the 3 Series convertible delivers quiet, comfortable, topdown motoring in sunny weather at temps as low as 40 degrees.

2007 BMW M6

More extreme? Than the BMW M5? Which, after all, is a luxury automobile packing a Formula 1-inspired, 500-horsepower V-10 engine that revs like a dentist's drill; a seven-speed, paddle-shift, sequential manual gearbox that Mark Webber might think got stolen from his BMW Williams; and an aluminum suspension so sophisticated you could drive over a newspaper and practically read it. More extreme than that?


Yes. Performance-wise, the BMW M6 is all the BMW M5 is and more. And less, too, in a few key areas where less is in fact more.


The powertrains in the two Ms are identical: that astounding V-10 coupled to the shift-without-a-clutch-pedal seven-speed SMG. Output and gear ratios are the same, too. The BMW M6 edges ahead, then, not with extra muscle but with reduced mass. Up top is a roof made of carbon-fiber-reinforced plastic (CFP), a material BMW first employed on the noggin of the BMW limited-edition M3 CSL. Compared with the conventional steel roof on the 645Ci, the BMW M6's carbon top is 55 percent lighter. Perhaps more important, it also lowers the car's center of gravity by nearly half an inch.


The Jenny Craig treatment doesn't end there. Specially developed, 19-inch forged-aluminum wheels, with spokes as thin as the plot of a Steven Seagal movie, save nearly four pounds per corner over comparable rims, BMW says. The BMW M6 also wears side panels and a rear deck made of lightweight fiberglass-reinforced plastic. And in a move sure to keep M6 owners awake at night with parallel-parking catastrophes dancing in their heads, the bumpers are made of the same exotic CFP as the roof, reducing weight over conventional designs, BMW claims, by 20 percent up front and 40 percent in back--but probably also nudging repair costs up into "we're gonna need a deposit first, sir" territory.

BMW Cars!!

This blog is gonna be about BMW cars, mostly the new ones, and maybe some of the M models of the past years, mainly because we're BMW fans too!!
