2015 BMW M4 Convertible is here to put wind in your sails

Each generation of the BMW M3 has included a convertible model. Even the distant E30, the patriarch of the M3 line, had an ultra-rare (only 787 were built) droptop model. The convertible became more common on the successive generations, with the hardtop-convertible E93 being the most recent. Considering this history, there seemed very little doubt that as the M3 became the M4, a convertible would be in the cards. Now, the new droptop has arrived.
Set for its global debut at the 2014 New York Auto Show, the 2015 BMW M4 Convertible features, like its forbearers, everything that's great about the hardtop variant while adding an unlimited amount of head room. That means the same 3.0-liter, 425-horsepower, 406-pound-foot, twin-turbocharged straight six sits under its domed hood, while either a six-speed stick or a seven-speed M dual-clutch transmission dispatches power to the fat rear tires.
As for specific differences between the hardtop and the new convertible, obviously, the droptop is heavier. A lot heavier. Where an M4 with a six-speed manual tips the scales at 3,530 pounds, the M4 Convertible weighs in at 4,055 pounds. Believe it or not, BMW has actually trimmed 90 pounds from the last-generation M3 convertible, code-named E93. This marginal weight reduction from the third-generation convertible to the fourth is barely half of the 174 pounds BMW was able to subtract when transitioning from M3 Coupe to M4 Coupe.

Why won't automakers slap on a turbo badge anymore?

Where have all the turbos gone? Not the actual pieces that go in the engine, mind you, those are everywhere these days as automakers downsize cylinder counts and boost efficiency and CO2 claims. But the turbo badges and fanfare are missing. Back when turbos were something to get excited about there was "turbo-driven," "turbonium," and "The Turbo Zone," among other silly lines. But now that basically every car is getting some sort of boost even on the lowliest trims, automakers are almost sliding in the turbos under the radar. Or if you look at some of the nomenclature, pretending they don't exist at all. The 911 Turbo badge shows where the car goes from being sane to lunatic. It's an important border. The latest automaker to hide that it has boosted the turbo presence is Porsche with the 2017 911 lineup. Even the standard Carrera models now get turbocharged flat-six engines, meaning the 911 Turbo models aren't quite as special as they once were. Porsche is in a sticky situation with this. The 911 Turbo, after all, signifies where the 911 family takes off from being a sports car and becomes the Ferrari fighter. The 911 Turbo badge shows where the car goes from being sane to lunatic. It's an important border, but now Porsche has crossed it and is trying to downplay the fact. There are a lot of exaggerations with displacement badges today, with claims the 2.0-liter turbo four in a Mercedes C Class equates to a naturally aspirated 3.0-liter six to make a C300. Volvo is pretty far up there, too, saying an XC90 T8 means V8 power, even though it's a 2.0-liter turbocharged and supercharged four with electric assist. I don't know why BMW can't just call the car a 330i Turbo, rather than inflating the numbers up to 340i. Saab tried all of this back in the '90s when it decided to turbocharge its entire lineup, from light pressure units all the way up to models actually called "Saab 9-3 HOT" (for high-output turbo). But then the brand deleted any external reference to the turbo under the hood and people wondered why they were buying a $42,000 four-cylinder convertible. And that didn't turn out well. Even though these turbo replacements often make more power than their naturally aspirated predecessors, they're very different engines. People knew something changed when they exchanged their leased 328i with a 3.0-liter six for a 328i with a 2.0-liter turbo four.

Refreshed 2016 BMW 3 Series adds two new models to the range

The BMW 3 Series had years standing at the forefront of the luxury sedan segment, but competitors have continued to get better at challenging its long reign. To make sure the stalwart model can keep up, BMW is bringing some new powertrains and other upgrades to the range with a refresh for the 2016 model year. Plus, the exterior sees a very slight styling update. There are two big additions in the 3 Series range for 2016. First, there's the new 340i with the B58 turbocharged, inline-six engine to replace the 335i. Displacement is still 3.0-liters, but the latest mill makes 320 horsepower and 330 pound-feet of torque – gains of 20 hp and 30 lb-ft over the outgoing model. BMW estimates the 340i can reach 60 in 4.8 seconds with the standard eight-speed automatic or in 4.6 seconds with xDrive. A six-speed manual is also available as a no-cost option. The other new member of the family is the 330e plug-in hybrid, and it joins the lineup later in the year. BMW isn't specifically talking about the PHEV's powertrain, but the company estimates total output of 250 hp and 310 lb-ft. The sprint to 60 is forecasted at 6.1 seconds, and the range on electric power is predicted at 22 miles. Fuel economy isn't disclosed yet. Beyond these two models, there are a host of other upgrades under the skin for the 3 Series. The eight-speed automatic should be slightly more efficient thanks to wider gear ratio, and the handling is reworked with new front struts, rear dampers, and retuned electric power steering. There's also a Track Handling Package for gas-fueled models that combines Variable Sport Steering, Adaptive M Suspension and M Sport Brakes with high-temperature pads. The nav system accepts over-the-air map updates now, as well. You certainly can't see all of the changes on the outside, though. For the 2016 3 Series, BMW's designers tweak the front fascia slightly and update the headlights. LED units are optional on the 320i, 328i, and 328d, and they're standard on the 340i. The rear features reshaped LED taillights, and inside there's additional ambient lighting and chrome trim. In one other small adjustment, the look of the Sport Line package with black trim on the grille, B-pillars and rear bumper is now included on the 328i, 328d and 340i.
