2015 BMW M4 Convertible Quick Spin [w/video]

Quite a while ago, we ran a story where our editors disclosed their guilty pleasure cars. There, I admitted my love for the ultra-comfortable Acura RLX. But I have another automotive guilty pleasure, and it's the BMW M4 Convertible, and the droptop M3 that came before it, as well. Whether it's an E46, E93, or the new F83 M4 model, I just love the idea of a droptop M car. It kind of goes back to my Lexus RC F review, where I posit that most consumers buy a car like this solely for the image. To the point of this car, if you're opting for a convertible, you're boldly throwing out any pretense that you bought this car for its performance. It's a different and far grander indulgence than something like a droptop Ford Mustang, Chevrolet Camaro, or even a Corvette, and that's especially the case with the new M4, as I found out after a week at the wheel. Driving Notes Anyone that's listened to me on the Autoblog Podcast knows I've been none too kind about the state of BMW's turbocharged M cars. In effect, they're too easy to drive. In older models, the narrow power band meant you needed to always keep an eye on the tach, lest you fall into a weak zone. But because today's turbocharged M engines are so damn torquey, you can simply mash the throttle, regardless of engine speed or gear, and zoom forward. That's mostly the case here, although with a 7,500-rpm redline, the M4 at least maintains the illusion that you have to keep the revs up. Power delivery is fast and immediate, capable of catapulting the M4 towards the horizon at even half throttle. But more than the brutal power delivery, this latest M entertains with a strange but familiar singing voice. It's an almost feral, straight-six howl, particularly high in the rev range. But because of the single-scroll turbochargers and today's sound-tuning sorcery, the noise here is far richer and complex than what you'd get in a naturally aspirated M car, like the old E46. The turbos hiss and spit, and wide-open-throttle upshifts come with a cackling snap from the quad-tipped exhaust. Despite my belief that M cars' manual transmissions are generally pretty lousy these days, the M4's gearbox is far better than what you'll find in an M5. The clutch is more forgiving than in the larger sedan, too. With a broad catchpoint and a linear action, it feels natural and intuitive to work.

At meeting with automakers, Trump launches new attack on NAFTA

WASHINGTON — Ten American and foreign automakers went to the White House on Friday to push for a weakening of U.S. fuel efficiency standards through 2025, while President Donald Trump used the occasion to launch a fresh attack on the North American Free Trade Agreement that has benefited the companies. A draft proposal circulated by the U.S. Transportation Department would freeze fuel efficiency requirements at 2020 levels through 2026, rather than allowing them to increase as previously planned. Trump's administration is expected to formally unveil the proposal later this month or in June. "We're working on CAFE standards, environmental controls," Trump told reporters at the top of the meeting, referring to the Corporate Average Fuel Economy standards for cars and light trucks in the United States. Trump said he wants automakers to build more vehicles in the United States and export more vehicles. But much of the hour-long meeting focused on NAFTA. Trump blasted the pact involving the United States, Canada and Mexico as "terrible" and noted that negotiations to make changes sought by his administration were ongoing. "NAFTA has been a horrible, horrible disaster for this country and we'll see if we can make it reasonable," Trump said. Automakers have called NAFTA a success, allowing them to integrate production throughout North America and make production competitive with Asia and Europe, and have noted the increase in auto production over the past two decades with the deal in place. They have warned that changing NAFTA too much could prompt some companies to move production out of the United States. The chief executives of General Motors Co, Ford Motor Co, Fiat Chrysler, along with senior U.S. executives from Toyota Motor Corp, Volkswagen AG, Hyundai Motor Co, Nissan Motor Co, Honda Motor Co , BMW AG and Daimler AG met with Trump, as did the chief executives of two auto trade groups. Major automakers reiterated this week they do not support freezing fuel efficiency requirements but said they want new flexibility and rule changes to address lower gasoline prices and the shift in U.S. consumer preferences to bigger, less fuel-efficient vehicles.

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.
