More head-up displays are coming to a dashboard near you

With the exception of Apple products — $1,000 for a freakin' smartphone? — one great thing about tech is you typically get more for your money with each passing year. This is particularly true with automotive tech: Features like driver assists and surround-view cameras that were once exclusively available in luxury vehicles now come standard even on some economy cars. The same thing is slowly happening with head-up displays (HUD). For example, the 10-inch HUD in the 2018 Toyota Camry is one of the largest and best HUDs I've seen in any car. And a big improvement on the much smaller HUD in the latest Toyota Prius. Mazda is another mainstream brand that offers HUDs in several of its vehicles. But instead of embedding expensive components in the dash and using a special windshield, the HUDs in the Mazda3 and Mazda6 use a thin plastic lens that folds down when not in use. MINI has a similar solution, but this low-cost approach has limits in terms of size and position of the images compared to traditional HUDs that use the windshield as a screen. We're also starting to see similar lens-based aftermarket options that can be added to any car. Last year I tested a portable HUD called Navdy that taps into a car's OBD-II port to provide info on speed and RPM and uses built-in GPS and Google Maps to show the surrounding area, display speed limits and route you to your destination. Navdy also connects to an Android or iOS smartphone via Bluetooth to display data from phone calls, texts and music playing on a connected device, and it's simple to use and easily visible in almost any lighting condition. While Navdy is still available online, late last year the company ran into financial difficulties, and product support has been halted. I recently tested a new portable HUD called Hudly that's not quite fully baked and falls short of Navdy because it doesn't tap into an OBD-II port. Since a companion smartphone app for Hudly isn't scheduled to launch until next month, for now it only mirrors what's on a smartphone. So it can be used for nav and other apps, and its features are very limited. Between automakers adding HUDs in more reasonably priced cars and the aftermarket filling in the gaps for existing vehicle owners with add-ons, the technology is becoming more prevalent and affordable. And it's also getting better.

This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.

Mazda and Fiat finalize deal for Alfa roadster, next-gen MX-5 Miata

Although a little bit later than expected, Mazda and Fiat have signed a final agreement that will bring a next-generation MX-5 Miata to the Japanese automaker and a new roadster to Alfa Romeo. When the proposed arrangement was announced back in May, the two automakers had hoped to seal the deal last year, but it doesn't appear that the production timeline for these cars has slipped any, with both expected to start rolling off assembly lines in 2015.
Other than a shared chassis with a rear-wheel-drive layout, it sounds like the two cars are still planned to be distinct in their own ways from their styling right down to their engines. Mazda will produce both cars at a plant in Hiroshima, Japan, but it isn't clear what role each automaker will play in the cars' developmental process. The big question, of course, is what clever portmanteau name we can come up with, like Toyobaru. Mazda Romeo is the easy choice, but Alfazda might roll off the tongue a little better.
