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.

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.

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.
