Nine cars we wish were convertibles

The snow has melted, the sun is shining, and the days are getting longer. At the Autoblog Detroit office we feel like our winter hibernation is finally over. And with warmer temperatures come visions of opening up a convertible roof and cruising. You know, just turn up the bass and let the Alpine blast. There are plenty of droptops on sale in the US, and more on the way (like the 2016 Mazda MX-5 Miata). That said, we always want more. More! More! More! In that spirit, we cooked up a list of nine cars aren't currently sold as convertible, but ought to be. Check out our picks, below. Summer's just around the corner. Subaru BRZ / Scion FR-S In some parallel universe, this car actually happened. Toyota showed us a FT 86 Convertible concept at the Geneva Motor Show in 2013, and we immediately started licking our chops over the thought of a rear-wheel-drive convertible based on the Subaru BRZ and Scion FR-S twins. These days, the MX-5 Miata is our only option for affordable roadster fun. A competitor to the Mazda seems like a no-brainer to us, especially since we have naught but good to say about the BRZ/FR-S as-is. Unfortunately in our present timeline, this car is as likely for production as a BRZ STI. Which is to say, not very. Dang. Lexus RC F Unlike the FR-S, a convertible from Toyota's luxury division might actually see the light of day. The current IS convertible is about to be phased out, and the Lexus LF-C2 concept from the 2014 Los Angeles Auto Show is really a thinly veiled look at a possible RC convertible. A droptop RC would be plenty good, but let's reach for the starts. What we really want is to run topless in an RC F, complete with that powerful, loud, 5.0-liter V8 engine. Lexus says the RC F is a true competitor to the BMW M4. If that's true, it only makes sense for Lexus to mimic the Germans and offer its performance coupe in a folding hardtop form. Maybach Landaulet Maybach is bach back, recast as an upper crust trim level for Mercedes-Benz. The Mercedes-Maybach S600 is seriously awesome, and more luxurious than a trip to the spa. But why not go a step into the truly ridiculous levels of extravagence and bring back that open-top Landaulet? We think your local princess will love this idea, and with better S-Class bones underneath, Jeeves will have a pretty enjoyable ship to steer, too. Besides, with that slick new Mercedes design language, a Landaulet redux wouldn't be nearly as hideous as the old model, pictured here.

2019 Hyundai Nexo First Drive Review | Promise for fuel cells

According to the Kardashev scale of measuring advanced civilizations, a Type I civilization is able to harness all the power available on its home planet, including solar, wind and geothermal. A Type II civilization harnesses all the power generated by its sun. A Type III civilization harnesses all the energy of its home galaxy. Humanity, as physicist Michio Kaku is fond of saying, is a Type 0: We derive all our energy from burning dead plants and animals. And humanity being what it is, we still prefer crossovers by a vast margin. Fine, says Hyundai. We'll give you what you want, but we're going to nudge you toward Type I in the process. For 2019, the Korean automaker is launching a double-pronged attack on the internal-combustion engine with a pair of crossovers — a pure-electric version of the Kona and the hydrogen-powered Nexo. Hyundai is taking this approach because it believes electric and hydrogen fuel cell vehicles actually serve two different purposes. According to Dr. BoKi Hong of the company's fuel cell R&D division, the future won't see a one-solution-fits-all revolution in post-internal-combustion-engine (ICE) propulsion. Smaller vehicles — cars, motorcycles, Bird scooters — will be able to run solely on electricity, but Dr. Hong says that larger vehicles — cargo trucks, buses — will be powered by hydrogen fuel cells. The reason? Scalability. The larger the vehicle, the less sense it makes to equip it with a battery pack. Weight, cost and refueling time all increase along with the size of the conveyance. The longer the distance they have to travel — think cargo haulers or cross-country buses — the less sense it makes to use a battery electric vehicle (BEV). Hydrogen, on the other hand, offers a much more efficient way of storing and transporting energy. A fuel cell drivetrain can be scaled up to fit larger vehicles, but it doesn't require the same proportion of material as a battery. Plus, filling up your hydrogen tanks is as quick as a gasoline top-off, an advantage for long-distance haulers. Hyundai believes there's room for fuel cell vehicle (FCV) passenger cars as well, and the Nexo is Hyundai's latest take on a hydrogen car. Its first was introduced in 2000, based on a Santa Fe. That was followed in 2013 by a Tucson-based FCV. Unlike those, the Nexo arrives on an all-new platform not shared with an existing ICE-powered car. As it did with the Kona EV, Hyundai is offering a crossover in a segment where one doesn't really exist.

Hyundai returns to spark-compression engines with $5 million grant

Ed note: This version adds comment from a Hyundai spokeswoman. Hyundai said Monday it has won a grant worth $4.95 million from the U.S. Department of Energy to support research and development for an advanced, mixed-mode gasoline spark-compression engine, meaning the Korean automaker appears to be back at it in its quest to develop a fuel-efficient, low-emissions gasoline compression engine that can catch the likes of Mazda's Skyactiv-X. Hyundai says the three-year grant will leverage existing work with advanced valve train and previous DOE-funded technologies. Hyundai previously was working on its own HCCI — short for homogeneous charge compression ignition — project, developing a Gasoline Direct-Injection Compression engine with help from Delphi that used supercharging and turbocharging, a high compression ratio and fully variable valve train. But it has never come to fruition, reportedly due in large part to added costs. Hyundai spokeswoman Michele Tinson said the grant will support a new project for the automaker. "It's a departure from the past efforts forging a new direction forward for Hyundai where the fuel and engine combustion modes can be optimized to meet new targets," she said. Tinson said the GDCI project is completing its third round of DOE funding. Hyundai in December said it plans to release 38 environmentally friendly vehicles along with its affiliate Kia, and using a variety of technologies, by 2025. Hyundai alone will account for 18 of them. The aim is to use the spark-compression engines for conventional gasoline-powered vehicles, plug-in hybrids and mild hybrids. "The opportunity to explore mixed-mode engine technology through the DOE's grant signifies Hyundai's commitment to advanced research technology and compression engines," John Juriga, director of powertrain technologies at Hyundai America's Technical Center near Ann Arbor, Mich., said in a statement. "The co-operative research project along with Michigan Technological University and Phillips 66 signifies the importance in developing fuel and engine innovations that work together for optimal vehicle performance and leading fuel economy ratings." Mazda's Skyactiv-X compression-ignition engine uses Spark Controlled Compression Ignition to achieve diesel-like gains in fuel economy — about 20 to 30 percent higher than its current gasoline engines — and lower emissions from regular gasoline. It's said to debut in late 2019. Related Video:
