The compact drop-top is getting its very-first mid-cycle refresh

The BMW 4 Series made its global debut in 2013, right after the German brand decided to split the two- and four-door versions of the 3 Series into different nameplates. While the 3 Series kept the sedan body style, the coupe and convertible were rebadged as 4 Series models. Despite the different name, the 3 Series and 4 Series shared everything from platform and drivetrains to exterior design and interior features. Come 2017 and BMW launched mid-cycle facelifts for the entire range, including the 4 Series Convertible.

After nearly three successful years on the market against dated competition from Mercedes-Benz and Audi, the 4 Series Convertible finally has something to worry about. With Mercedes-Benz and Audi having introduced redesigned versions of the C-Class Cabriolet and A5 Cabriolet, the Bimmer will have a hard time until a new-generation model is designed. However, the facelift brings a few updates inside and out that might keep BMW enthusiasts coming into dealerships for a few more years.

If there’s one thing I’ve learned about facelifts in recent years is that they don’t do much to change a car’s exterior design. This holds true for the 4 Series Convertible as well, which gained only a few nips and tucks. In fact, if you’ve already seen the coupe version of the 4 Series, you’ve pretty much seen the convertible below the waist, as the upgrades are unsurprisingly identical.

Arguably the most important revision to talk about is the new lighting system. Previously sold with xenon headlamps, the 4 Series Convertible now sports LED lights. The cluster design is also different, but not by much. The foglamps also use LED technology and are now standard in this configuration. Around back, the Bimmer has LED taillights for the very first time.

Arguably the most important revision to talk about is the new lighting system. Previously sold with xenon headlamps, the 4 Series Convertible now sports LED lights.

BMW also talks about modified air intakes in the front bumper and model-specific trim in the rear apron, but these changes are so mild that they’re barely visible. On the other hand, each of the four versions – Advantage, Sport Line, Luxury Line, and M Sport – get their own specific wheel designs. The facelift is rounded off by two new exterior colors, Snapper Rocks Blue and Sunset Orange, both of which are exclusive to the 4 Series line.

Now I’m not saying that the 4 Series Convertible is poorly equipped, just don’t look for too many extras compared to the outgoing model.

If you’re expecting to find significantly more new features inside the cabin, you’ll most likely end up disappointed. Now I’m not saying that the 4 Series Convertible is poorly equipped, just don’t look for too many extras compared to the outgoing model. The first thing you’ll notice is the double stitching on the dashboard. This is a nice touch as it enhances the cabin’s premium feel. BMW also added a center console in high-gloss black and new chrome trim on the dash and door panels. These are joined by three new upholstery colors and three new interior trim strips, which means you have more ways to customize your car. New upholstery colors include Midnight Blue Dakota, Cognac Dakota, and White Dakota leathers. New interior trim includes Carbon Aluminum, Light Fineline, and high-gloss black with Pearl Chrome.

The styling add-ons stop here, and if you want other extras, you’ll have to look under “optional” on the technology equipment list. First up is the Professional navigation system, which features an interface with large tile-style control pads. This makes it easier to use, as the pads can be arranged as desired and display a constantly updated version of the menu content. Then there’s the optional Multifunctional Instrument Display, which brings new visualization options specifically tailored to the driving mode selected.

Drivetrain

2018 BMW 4 Series Convertible Exterior High Resolution
- image 702218

Under the hood, the 4 Series Convertible continues with a wide range of drivetrain options. Specifically, there are no fewer than 31 different model and powertrain variations, including four- and six-cylinder engine sipping either gasoline or diesel. It may sound a bit complicated, but it’s not that terrifying once you figure out which trim uses which engine.

The gasoline lineup actually includes three badges. There are the 420i and 430i, which are equipped with the 2.0-liter four-cylinder, and the 440i that gets the 3.0-liter inline-six. The 420i cranks out 181 horsepower and up to 214 pound-feet, while the 430i generates a stout 249 horses and 258 pound-feet of twist. The 440i, which is the range-topping non-M version of the drop-top, comes with 322 and 332 pound-feet of torque on tap. These engines are paired to either a manual or a dual-clutch transmission, while all-wheel-drive, or xDrive in BMW talk, is optional.

Although not available in the United States, the M4 Convertible gets three diesel powertrains in Europe. First up is 420d, a 2.0-liter four-cylinder good for 187 horsepower and 295 pound-feet of twist. More oomph comes from the 430d version, which uses a 3.0-liter six-cylinder engine tweaked to generate 254 horses and 413 pound-feet of torque. Finally, the 3.0-liter six-cylinder in the 435d model sends a solid 309 horses and 465 pound-feet of twist to the wheels. Transmission choices as similar here, with the six-speed manual and seven-speed dual-clutch to choose from. The xDrive system is optional on the 420d and 430d but comes standard on the range-topping 435d.

As far as performance goes, getting to 62 mph from a standing start ranges between 7.6 and 4.7 seconds. The 420i is the slowest of the bunch, while the 435d xDrive is the quickest. Yes, the diesel is three-tenths quicker than the 440i gasoline model, which makes it even more frustrating if you live in the U.S. and want the fastest 4 Series Convertible.

While the 4 Series Convertible is already four years old as of 2017, the C-Class Cabriolet was brand-new for the 2017 model year. Taking cues from the latest S-Class Cabriolet, the compact drop-top blends sporty and elegant design features and is regarded as one of the sexiest convertibles on the market. The interior is almost identical to the C-Class sedan and coupe, but it comes with its very own comfort features, including the AirScarf neck heater and the AirCap automatic draft stop system. Under the hood, it gets a wide range of gasoline and diesel engines, but in the U.S. it only comes with the 2.0-liter turbo-four rated at 241 horsepower and 273 pound-feet of torque with either RWD or AWD. Pricing starts from $50,900, which makes the C-Class Cabriolet very competitive against the 4 Series.

Around since 2009, the first-generation A5 Cabriolet was finally redesigned for the 2017 model year, giving us a third option in this niche. Built around the previous model styling-wise, the new A5 Convertible boasts a more aggressive appearance with sharper body lines. The interior is brand-new with Audi’s new continuous air-vent strip dashboard and latest technology. Under the hood, Audi offers four- and a six-cylinder options. The 2.0 TFSI trim comes with 252 horsepower and 273 pound-feet of twist, while the base diesel, the 2.0 TDI, cranks out 190 horses. Moving over to the range-topping diesel version, the 3.0 TDI, it gets 216 horsepower. Pricing starts from $49,600.

Comparing the German premium compacts to the Chevy Camaro might have seemed ridiculous a few years ago, but the pony car has come a long way as GM upped the ante in just about every department, including moving it closer to the premium market. Redesigned for 2016, the current Camaro is also more compact and significantly lighter, which makes it more of a sports compact rather than a traditional muscle car. Inside, we find softer materials, better fit and finish, and GM’s latest-generation MyLink system with improved connectivity and features. It also has a LED ambient system that comes with a unique 24-color package and a theatrical mode that cycles randomly through the entire color spectrum when the car is parked. It also has a turbo, 2.0-liter four-cylinder engine that delivers 275 horsepower and 295 pound-feet of torque alongside unprecedented fuel economy for a Camaro. The 3.6-liter V-6 cranks out a competitive 335 horsepower and 285 pound-feet of twist. Pricing starts from $33,695 for the four-pot model and $35,190 for the V-6, both stickers being significantly more affordable compared to the competition. For less than $45,000, you can actually order the V-8-powered SS model, which offers M4-competing levels of performance at 455 horsepower and 455 pound-feet of twist.

When it was launched in 2013, the 4 Series Convertible was miles ahead of its competitors. It had way better technology, more fuel efficient engines, and its design was fresh and modern. Four years have passed and things changed dramatically in the compact premium segment. Granted, the 4 Series is still an appealing two-door with cool gadgets and strong performance, but BMW has two new rivals to worry about. Mercedes-Benz launched a brand-new C-Class Cabriolet, while Audi just unleashed the redesigned A5 Convertible. It’s going to be tough for the 4 Series Convertible, but the German machine appears to have what it takes to survive for another three years among stiffer, newer competition.

Press Release

Endowed with an aesthetic appeal and dynamic flair all of its own, the BMW 4 Series has stood out with its supremely assured and stylish air ever since its launch. A total of nearly 400,000 sales worldwide (up to the end of 2016) is testimony to the tremendous allure of the BMW 4 Series, whose story began in 2013 with the arrival of the BMW 4 Series Coupe. The following year, it was joined by the BMW 4 Series Convertible and the BMW 4 Series Gran Coupe to create a complete model family. The cars are manufactured in Munich (BMW 4 Series Coupe), Regensburg (BMW 4 Series Convertible) and Dingolfing (BMW 4 Series Gran Coupe).

The new BMW 4 Series models write the next chapter in this success story with even sharper styling and revised suspension.

Restyled LED headlights take the place of the outgoing cars’ xenon units. And all models in the range are equipped with LED front foglamps as standard. The LED rear lights fitted on the BMW 4 Series for the first time give extra impact to the car’s powerful looks. Modified air intakes, line-specific applications and the new rear apron add further striking touches.

Moving inside, the new electroplated detailing, chrome applications and centre console in high-gloss black reinforce the exclusive, high-quality feel. Another visual highlight is the double stitching on the instrument panel, while three new upholstery colours together with three new interior trim strips provide even greater choice when it comes to personalising the interior’s design.

The two new exterior paint finishes Snapper Rocks Blue and Sunset Orange are available exclusively for the new BMW 4 Series models, and there is also one new model-specific wheel design each for the Advantage, Sport Line, Luxury Line and M Sport equipment lines. An abundance of additional equipment options offers ample scope for tailoring the car to individual tastes.

Revised suspension.

The new BMW 4 Series Coupe and BMW 4 Series Gran Coupe now come with a stiffer suspension set-up delivering even sportier handling without any loss of ride comfort. Both the lateral and longitudinal dynamics have been improved, regardless of the load on board. This applies not only to the standard suspension, but also to the M Sport suspension and the Adaptive suspension. All new BMW 4 Series models now boast even more assured straight-line stability and more communicative steering. High-performance tyres are available as a factory-fitted option for all models from the BMW 430d and BMW 430i upwards.

31 model and powertrain variants.

All of the petrol engines and the four-cylinder diesel units fitted in the new BMW 4 Series range stem from the latest BMW EfficientDynamics family of engines and are equipped with BMW TwinPower Turbo technology. There are three petrol engines (BMW 420i, BMW 430i and BMW 440i) and three diesel options (BMW 420d, BMW 430d, BMW 435d xDrive) available for all of the new BMW 4 Series models.

The power output of the petrol-engined BMW 4 Series model variants ranges from 135 kW / 184 hp in the BMW 420i up to 240 kW / 326 hp in the BMW 440i (fuel consumption combined: 7.9 – 5.5 l/100 km [35.8 – 51.4 mpg imp]; CO2 emissions combined: 185 – 127 g/km). When it comes to the diesel line-up, meanwhile, the power spectrum extends from 140 kW / 190 hp in the BMW 420d up to the 230 kW / 313 hp of the BMW 435d xDrive (fuel consumption combined: 5.9 – 4.0 l/100 km [47.9 – 70.6 mpg imp]; CO2 emissions combined: 155 – 106 g/km).

The BMW 4 Series Gran Coupe is available in a further diesel variant – the BMW 418d with an output of 110 kW / 150 hp (fuel consumption combined: 4.5 – 4.1 l/100 km [62.8 – 68.9 mpg imp]; CO2 emissions combined: 118 – 107 g/km).

New navigation and instrumentation displays.

The optional Navigation system Professional for the new BMW 4 Series now features an interface with large tile-style control pads that is even easier to use. The control pads can be arranged as desired and display a constantly updated version of the linked menu content, making operation even more intuitive for users.

The BMW 4 Series range can be optionally fitted with the Multifunctional Instrument Display, giving the driver the choice of different visualisation options for all displays depending on the driving experience mode selected.

Sharper design for the BMW M4, too.

The BMW M4 Coupe and BMW M4 Convertible now come as standard with the adaptive full-LED headlights. And the newly designed full-LED rear lights again freshen up appearances and inject technical appeal. Besides this, a number of styling touches have been added to give the cabin of the sportiest BMW 4 Series variants an even more sophisticated air. And the two M4 models likewise feature the updated version of the Navigation system Professional and other ConnectedDrive features.
