These are the cars with the best and worst depreciation after 5 years

The average new vehicle sold in America loses nearly half of its initial value after five years of ownership. No surprise there; we all expect that shiny new car to start depreciating as soon as we drive it off the lot. But some vehicles lose value a lot faster than others. According to data provided by iSeeCars.com, trucks and truck-based sport utility vehicles generally hold their value better than other vehicle types, with the Jeep Wrangler — in both four-door Unlimited and standard two-door styles — and Toyota Tacoma sitting at the head of the pack. The Jeep Wrangler Unlimited's average five-year depreciation of 30.9% equals a loss in value of $12,168. That makes Jeep's four-door off-roader the best overall pick for buyers looking to minimize depreciation. The Toyota Tacoma's 32.4% loss in initial value means it loses just $10,496. The smaller dollar amount — the least amount of money lost after five years — indicates that Tacoma buyers pay less than Wrangler Unlimited buyers, on average, when they initially buy the vehicle. The standard two-door Jeep Wrangler is third on the list, depreciating 32.8% after five years and losing $10,824.

On the other side of the depreciation coin, luxury sedans tend to plummet in value at a much faster rate than other vehicle types. The BMW 7 Series leads the losers with a 72.6% drop in value after five years, which equals an alarming $73,686. BMW's slightly smaller 5 Series is next, depreciating 70.1%, or $47,038, over the same period. Number three on the biggest losers list is the Nissan Leaf, the only electric vehicle to appear in the bottom 10. The electric hatchback matches the 5 Series with a 70.1% drop in value, but since it's a much cheaper vehicle, that percentage equals a much smaller $23,470 loss.

Hydrogen could deliver one fifth of world carbon cuts by 2050, industry says

BONN, Germany — Increasing the use of hydrogen in power, transport, heat and industry could deliver around one fifth of the total carbon emissions cuts needed to limit global warming to safe levels by mid-century, a report by the Hydrogen Council said on Monday. To encourage industries to use hydrogen, Toyota and Air Liquide helped set up the Hydrogen Council, a global lobby launched in January this year. Its 27 members include automakers Audi, BMW, Daimler, Honda and Hyundai, and energy firms such as Shell and Total. The council said using hydrogen for transport, energy generation, energy storage, industry, heat and power could cut annual carbon emissions by 6 billion tonnes by 2050. "This would ... contribute roughly 20 percent of the additional abatement required to limit global warming to two degrees Celsius," the council said in a report released on the sidelines of a U.N. climate conference in Bonn. To achieve a two-degree limit this century agreed by governments in Paris in 2015, the world must reduce energy-related carbon emissions by 60 percent by 2050. The report said one in 12 cars sold in California, Germany and Japan were expected to be powered by hydrogen by 2030. By 2050, hydrogen could power 400 million cars, 15 million to 20 million trucks, around 5 million buses, a quarter of passenger ships and a fifth of non-electrified train tracks, as well as some airplanes and freight ships. Achieving this shift in transport and other sectors would require investment of $280 billion by 2030, with about $110 billion to fund hydrogen output, $80 billion for storage, transport and distribution, and $70 billion to develop products. Fuel cell vehicles combine hydrogen and oxygen to produce electricity to power an electric motor, producing water as a byproduct. However, making hydrogen from fossil fuels, a common route, also produces some greenhouse gas emissions. So far the take-up of hydrogen vehicles is tiny and industry experts say their wider use is years away, with high purchase prices and a lack of refueling stations the major barriers. But some firms, such as miner Anglo American and carmaker Toyota, are pushing for fuel cell cars to play a role even with the rise of battery-powered electric vehicles (EVs). Woong-chul Yang, vice chairman of automotive research and development at Hyundai said EVs and hydrogen fuel cell cars were needed because EVs were better for city driving and fuel cell vehicles better for longer journeys.

The 2018 Audi A5 and S5 Cabriolets are here just in time for winter

There are no big surprises with the 2018 A5 and S5 Cabriolet. As you'd expect, the convertibles share a design with their coupe counterparts, the A5 and S5 coupes, refreshed versions of which were unveiled earlier this year. Alongside the coupes and upcoming sportback models, the Cabriolets complete the A5 lineup. At least until another RS 5 comes along. In Europe, the A5 will have five available engine options, including three TDI engines maxing out at a 286-horsepower 3.0-liter, and two TFSI gas engines, with the most powerful putting out 252 hp. There will also be a choice of three transmissions including a six-speed manual, a seven-speed S-Tronic dual-clutch gearbox, and as an eight-speed automatic. For the US, though, the powertrains should be the same as the new coupe's, with a 2.0-liter turbocharged four-cylinder generating 252 hp and 273 lb-ft of torque in the A5, replacing the 220-hp turbo four in the previous model. An eight-speed automatic is a definite, although the existence of a manual A4 sedan for our market leaves some hope that a six-speed could be available in the A5 Cabriolet or at least the coupe. Audi also hasn't made final decisions on whether a front-drive model will be available here as it has been in the past. View 13 Photos The S5 Cabriolet, just like the two-door model, uses a new 3.0-liter turbocharged V6 engine that produces 354 hp and 369 lb-ft of torque, which is 21 more horsepower and 44 more pound-feet of torque than the old 3.0-liter supercharged V6 made. Despite the bump in power, the new S5 Cab hits 62 miles per hour in 5.1 seconds, just like the previous model. It is again electronically limited to 155 mph. And like the coupe, it will use an eight-speed automatic and get Quattro all-wheel drive standard. The A5 Cabriolet loses roughly 88 pounds compared to the previous model. The cars use an updated five-link front suspension and Audi claims the chassis is 40 percent stiffer than before. The soft tops have more insulation to cancel out road noise, take 15 seconds to open, and 18 seconds to close. You can do either at speeds up to 31 mph. The A5 Cabriolet will be available with Audi's latest array of driver assistance systems, including its navigation-linked adaptive cruise control and collision avoidance assist. A seven-inch display, seat belt microphones, Audi's Virtual Cockpit infotainment and gauge package, and a head-up display are available on the inside.
