Your guide to vehicle subscription services

They might be extremely limited in scope because of location availability, but vehicle subscription services are a growing trend that most luxury manufacturers are jumping on. Plans are expensive, but you're paying for much more than just the car typically. We highlighted four of the larger plans with a few more listed at the end. Care by Volvo Volvo launched its subscription service last year with its brand-new XC40. It was the only vehicle available for a time, but subscribers can now get an S60 sedan as well. Subscriptions are for two years, with the monthly price including insurance, a concierge service, wear-and-tear item replacements and all maintenance. You'll be able to drive 15,000 miles per year with whichever Volvo you choose, and although there are no options to extend that mileage, you can swap cars after a year. Pricing for the XC40 is $650 per month in base trim, while an S60 can be as expensive as $850 for the R-Design. Volvo's plan is to offer more cars soon through the service, but it's relatively limited compared to others right now. Porsche Passport Porsche has two levels in its subscription service: Launch and Accelerate. Launch will cost $2,000 per month and give you access to the Cayman, Boxster, Macan and Cayenne. All of those but the Cayenne can be had in "S" trim as well. Accelerate is where the fun really starts. For $3,000 per month you can choose from a fleet of 911s, including the S, 4S, Cabriolet and Cabriolet S. If those aren't enough, you can also get the Panamera 4S, Macan GTS and Cayenne S. There are no mileage limits and you can change vehicles as often as you'd like. Also included in the price is insurance, repairs, detailing and any maintenance. It might be extremely expensive and limited to Atlanta only, but this subscription service is second-to-none for what you get. Audi Select Audi just launched its subscription car service, and it's offered in one version for a flat fee of $1,395 per month. For that you'll have access to five different cars including the A4, S5 Coupe, A5 Cabriolet, Q5, and Q7. Not a bad range of vehicles, but it would've been neat to see the recently updated A7 in there too. Maybe in time. Like the others, insurance and maintenance are wrapped up in the price. Audi is allowing for unlimited miles and two car swaps per month here. In addition to that, you'll get two days of free rentals through Audi's Silvercar rental agency should you go on a trip.

Why we can't have better headlights here in the U.S.

It wouldn't be a European auto show if we weren't teased with at least one mainstream vehicle we can't have here. At the Geneva Motor Show last week, the small but vocal contingent of shooting-brake buffs lamented that the Mazda6 wagon won't be coming to our shores, although they can take comfort in the fact that the vehicle won't get the torquey 250-horsepower 2.5-liter turbocharged gasoline engine we'll get here. Mercedes-Benz also announced a new headlight technology in Geneva that likely won't be available here anytime soon. It's just the latest in a long line of innovative and potentially lifesaving front-lighting solutions that the federal government doesn't allow in this country due to outdated standards — and a current lack of leadership at the U.S. Department of Transportation. Mercedes-Benz's new Digital Light system that debuted in Geneva uses a computer chip to activate more than a million micro-reflectors to better illuminate the road ahead. The Digital Light headlamps works with the vehicle's cameras, sensors and navigation mapping to adjust lighting for the given location and situation and to detect other road users. The Digital Light technology also serves as an extended head-up display of sorts by projecting symbols on the pavement ahead to alert drivers to, say, slippery conditions or pedestrians in the road. And it can even project lines on the road in a construction zone or through tight curves to show the driver the correct path. Digital Light will be available on Mercedes-Maybach vehicles later this year, although like any technology it's bound to trickle down to less expensive vehicles. That is, if we ever get it here in the U.S. Audi, a leader in automotive lighting, has repeatedly run into snags trying to bring state-of-the-art car headlights to the U.S. The German luxury automaker's recently introduced matrix laser headlight system, which performs many of the same trick as Mercedes-Benz's Digital Light, also isn't legal on U.S. roads. And five years after the introduction of its matrix-beam LED lighting, which illuminates more of the road without blinding oncoming motorists with brights by simultaneously operating high and low beams, Audi still can't bring that technology to the U.S. either.
