To fill the gap in the 3-series lineup between the 300-hp 335i and the 414-hp M3, BMW is introducing the new 335is coupe and convertible. We were unaware that said gap needed to be filled, but we’re told that the 335i is seen in the U.S. as just an ordinary 3-series, and, as such, there’s room for something more exotic than a 335i but less outlandish than an M3. Now that we’ve been given the chance to drive the 335is coupe, we’re coming around to accepting this whole gap idea.

More Power and a Body Kit and …

Conceptually similar to the 330i Performance Package model that was available as part of the previous-generation 3-series lineup, the 335is doesn’t go so far as to threaten the M3’s supremacy, but it definitely ups the sportiness quotient. To that end, the 335is gets 320 hp and 332 lb-ft torque from the twin-turbo 3.0-liter inline-six engine, and an overboost function allows for seven-second blasts of 370 lb-ft of torque. Unlike the regular-grade 2011 335i, the 335is sticks with the older twin-turbo engine for the simple reason that BMW engineers had more experience tuning it. This same engine can also be found in the Z4 sDrive35is that was introduced at this month’s Detroit auto show. In the Z4, the engine makes 335 hp; a more restrictive intake on the 3-series accounts for the 15-hp difference.

A little after a leaked brochure gave us our first taste of the lightly refreshed 2011 3-Series Coupe and Convertible models, BMW rushed out an official release and a whole bunch of pictures. For the 2011 model year, the Bavarian automaker’s bread-and-butter coupe and cabriolet models receive some minor cosmetic touches and updated powerplants.

The most notable – that is, if you’re a hardcore bimmer fan- changes on the outside concern the widened kidney grille, reshaped LED headlamps, front and rear bumpers with restyled lower fascias, new exterior mirrors and finally, reworked tail light cluster with a new color scheme.

According to BMW, these modifications slightly extend the front and rear overhangs by 1.14 and 0.12 inches respectively.

The only change in the cabin concerns the convertible models and the use of sun-reflective technology to mitigate temperatures on leather seating, armrest surfaces, headrests, and gear shifter. BMW says that this new treatment is able to reduce surface temperatures on dark interior colors by up to 20 Celsius degrees (36 Fahrenheit degrees) and by as much as Celsius degrees (27 Fahrenheit degrees)on light-colored upholstery.

In North America (we’ll bring you details on the Euro spec models shortly), the 2011 3-Series Coupe and Convertible models will be offered once again in two flavors, the 328i and 335i.

As noted in our previous post, the 2011 335i is fitted with BMW’s new twin scroll single turbocharged 3.0-liter straight six, designated N55, that replaces the previous model’s N54 twin-turbocharged 3.0-liter straight six.

BMW says that even though output has remained the same as before at 300 horsepower and 300 lb-ft of torque, the new single turbo engine is more responsive, more fuel efficient, and cleaner-running than its predecessor.

The rear-wheel drive 335i Coupe and Convertible accelerate from 0 – 60 mph (96km/h) in just 5.3 (5.5 coupe automatic) seconds and 5.5 (5.7 cabrio automatic) seconds, respectively, when equipped with a six speed manual gearbox.

The all-wheel drive 335i xDrive coupe is slightly faster at 5.2 seconds (5.3 sec for the automatic model).

The 328i’s 230 horsepower, 200 lb-ft, 3.0-liter inline-6 engine has been carried over unchanged from the 2010 model.

No word yet on the sporty 335is variants with a tweaked 3.0-liter twin-turbo churning out 322HP that were mentioned in the leaked sales leaflet.

In the U.S. and Canada, the 2011 3 Series Coupe and Convertible models will go on sale in Spring 2010, with pricing set to be announced closer to the on-sale date.

While BMW had pretty much ruled out the possibility of creating a successor to the M variants of the Z3 and the previous Z4 with its new hardtop roadster, no one from Munich ever said that there wasn’t going to be a faster and more focused version than the Z4 sDrive35i.

That car is the Z4 sDrive35is -the ‘s’ is what makes the difference- and it will make its world debut at next month’s 2010 Detroit Auto Show before going on sale worldwide in Spring of the same year.

Bypassing BMW’s ridiculous naming system (Z4is or Z4 35is would have been just fine), the range topping Z4 features a more powerful version of the company’s 3.0-liter twin-turbocharged straight six and M-Sports styling and chassis packages.

At the heart of the Z4 sDrive35is is BMW’s 3.0-liter twin-turbo straight-six that benefits from optimized air supply and increased boost pressure. Output is lifted from 306HP to 340HP at 5,800 rpm while peak torque is increased to 450Nm or 332 lb-ft and is available from 1,400 rpm all the way to 4,500 rpm.

Furthermore, the modified engine management on the Z4 sDrive35is also allows the use of an Overboost function briefly increasing engine torque under full load by another 50Nm or 37 lb-ft to 500Nm or 369 lb-ft.

Power is driven to the rear wheels through a revised version of the firm’s seven-speed double clutch transmission with BMW announcing a zero to 100km/h sprint time of 4.8 seconds (0-60mph in 4.7sec) and an electronically limited top speed of 250km/h or 155mph.

BMW says that despite the increased performance over the standard Z4 sDrive35i, the ‘S’ model delivers the same fuel economy averaging 9.0lt/100km which is equal to 26.1 mpg US with CO2 emissions rated at 210g/km.

Aside from the powetrain upgrades, the Z4 sDrive35is also comes as standard with an M Sports Package including the M Aerodynamics Package and adaptive M Suspension.

The M Suspension, which features electronically controlled dampers, lowers the entire car by 10 mm or almost 0.4-in. The top-Z4 also gets a reprogrammed electronic power steering system that promises to offer increased feedback.

On the outside, the M package adds unique 18-inch alloy wheels with 19-inch rims available an option, a new front bumper, re-trimmed kidney grilles, matte silver exterior mirror caps, a new rear bumper with an integrated diffuser and specific tail pipes.

Finally, the interior has been enhanced with several features such as the M leather steering wheel with gearshift paddles, M footrest, sports seats, aluminium carbon trim, BMW Individual roof lining, M entry strips and footmats with coloured piping.

The revised instrument cluster with grey faces on the dials and the “sDrive35is” model designation complete the package.

The BMW 7-Series’ smaller brother both in terms of size and styling, the new 5-Series, was officially launched today. Key highlights include a less controversial exterior design that’s more muscular and draws heavily on the Bavarian firm’s flagship limousine and the return of the BMW’s driver orientated center console and the classic four circular gauges on the instrument panel. Add to that an increased length of 4,899mm or 192.9” (previous model: 4,841 mm or 190.6”) combined with a wheelbase of 2.968 mm or 116.9” (+80 mm or +3.15”) and a revised engine lineup that includes turbocharged inline-six and V8 units.

The increased length and what BMW describes as the largest wheelbase in the segment, are said to translates into an extra 13mm of knee room for the rear passengers, compared to the previous 5 Series, while the sedan also get a 520-litre boot with the option to specify 40:20:40 split folding rear seats.

The new 5-Series, codenamed F10, is based on the same platform as the 5-Series GT and the latest 7-Series sedan. The double wishbone layout up front is combined with a multilink axle at the back while for the first time, the 5 Series comes with Electric Power Steering with Servotronic assistance.

Those that specify the car with Variable Damper Control or Adaptive Drive packages, the Drive Dynamic Control (DDC) chassis configurator allows for fine tuning of the chassis with the choice of Normal, Comfort, Sport and Sport+ with each mode changing the levels of steering assistance, throttle response, gear change characteristics, degree of Dynamic Stability Control interaction and, courtesy of adjustable dampers, the ride and handling characteristics.

All models will come equipped with a Brake Energy Regeneration system that recharges the vehicle’s battery during engine over-run while the 520d is the first 5 Series to come with Auto Start-Stop.

So the Germans were wrong about the market’s desire for hybrids, and now they are trying hard to catch up. Proof? Even the 1-series, BMW’s self-proclaimed "spritual successor" of the 2002, is slated to gain a hybrid powertrain. As these spy photos show, prototypes using current 1er bodies are on the road. And while we don’t expect the 1-series to become available as a full hybrid, the next generation is almost sure to get an electric motor and a pack of batteries to allow owners an extra degree of eco-smugness.

While this 1-series hatch may seem unfamiliar to you, it is the standard body style for most other markets. Pretty it ain’t, but it provides a nice, flexible cargo area and works well in urban habitats. The next-generation 1-series will be based on the 3-series platform, as it is today, and it will be available with several body styles again, including hatch, coupe, and convertible.
