2016 Chevy Volt arrives with 50-mile EV range, 41 mpg [w/ video]

Let's start with the numbers. The 2016 Chevy Volt will have an all-electric range of 50 miles from a new, 18.4-kWh lithium battery. It will get 41 miles per gallon (combined) once the battery runs dry and have 102 MPGe. Oh, and it has five seats, sort of. To compare, today's four-seat 2015 Volt has a 38-mile range from a 17.1-kWh battery in a powertrain that offers 37 mpg and 98 MPGe. So, across the board, there are notable improvements. Now that that's out of the way, let's talk story. General Motors will unveil the new Volt at the Detroit Auto Show later today, but it's been talking about how this new version – the first major plug-in hybrid vehicle to get a serious redo in the modern era – was crafted with reams and reams of data from first-gen Volt customers. At a preview event for journalists last week, GM executive chief engineer Pam Fletcher told Autoblog that these owners "gave us the recipe" to make the second-gen model. At the top of the request list was more range (check), more "fun-to-drive" behavior (check?) and a smoother and quieter experience (we'll assume a check here, given that the new 1.5-liter four-cylinder – the first North American application of this new engine family – should offer more power with less noise than the previous 1.4-liter, four-cylinder powerplant). Other customer-driven changes in the new Volt include a different place to store the charging cable (in the side of the trunk instead of under the load floor) and a new brake system with improved blended regenerative braking feel as well as driver-selectable regen levels. The requested 50-mile range comes from a new, lighter battery that has increased capacity from fewer cells (192 vs. 288) and a simplified control architecture. Along with the new battery, the electric drive unit is a two-motor deal that is up to 12 percent more efficient and 100 pounds lighter, while also being "tremendously smaller," notes Fletcher. It offers 294 pound-feet of torque and a maximum 149 horsepower of "motoring power" delivered to the wheels. GM says it has worked hard to reduced the amount of rare earth materials in these motors, and one of them doesn't use any at all. The new powertrain offers improved acceleration times, as well. The 2016 Volt can go from 0 to 60 miles per hour in 8.4 seconds, a seven-percent improvement, while the 0-30 mph time has been improved by 19 percent, down to 2.6 seconds. The new Volt is more conventional looking, but certainly not completely ordinary.

More 2017 Chevy Bolt powertrain details revealed

We've seen the production version of the Chevy Bolt electric vehicle. We've driven a prototype version. And now it's time to get some details about the powertrain. After the production version's reveal at CES last week, GM trotted out the Bolt EV for its Detroit debut this morning. The company brought with it a bunch of technical specifications. We'll start with the most important part of an EV: the battery. GM has put a 60-kWh lithium-ion battery that weighs just just 960 pounds into the floor of the Bolt. As previously announced, the Bolt's 288 cells will be able to go over 200 miles on a full charge. That full charge takes nine hours on a Level 2 EVSE thanks to the onboard 7.2-kW charger. Of course, a full charge won't be that important most days, which is why GM says that you can get 50 miles of range in "less than two hours" on Level 2. There's a SAE Combo DC fast charging option as well. The battery will have an eight-year/100,000-mile warranty. The Bolt will be able to sprint up to 60 miles per hour in "less than seven seconds" thanks to a 150-kW/200 horsepower motor in the Bolt. The motor is a new GM design that can produce up to 266 pound-feet of torque. The Bolt uses a shift-by-wire system and an, "offset gear and shaft configuration tailored to meet efficiency and performance targets." The Bolt EV's powertrain has a 7.05:1 final drive ratio.

It also raises the bar when it comes to driving performance. Engineers developed the Bolt EV's propulsion system to offer more than an estimated 200 miles (based on GM estimates) and a delightful driving experience that's more akin to a compact sports sedan than a small utilitarian crossover. "Being the leader in range and affordability means nothing if the car isn't going to excite you each time you get behind the wheel," said Josh Tavel, Chevrolet Bolt EV chief engineer. "That's why the team was tasked with delivering a propulsion system that would also make the Bolt EV an electric vehicle that owners would love to drive." Single Motor Drive Unit Like most EVs on the road, the Bolt EV's drive system uses a single high capacity electric motor to propel the car.

2016 Chevrolet Spark gleams in green in New York

Take one look at the 2016 Chevrolet Spark that's debuting at the 2015 New York Auto Show, and you can immediately see that the little hatchback is growing up. The previous long headlights and tall greenhouse are gone in favor of a slightly more conventional look that suits the enlarged overall size well. To address complaints about a lack of power from the current Spark's 1.2-liter engine, the latest model gets a larger 1.4-liter unit making 98 horsepower. It can be paired with a five-speed manual transmission, but for those looking to maximize fuel economy, a CVT offers an estimated 40 miles per gallon highway fuel economy. Beyond the new engine, there's an upgraded platform underneath with a longer wheelbase. The underpinnings are also more rigid, as well, to help improve handling and lower interior noise. Inside, the Spark now gets some physical controls to go along with the seven-inch MyLink infotainment system. A rearview camera is standard, which seems almost unnecessary is such compact model, and buyers can further enhance safety with tech like a Forward Collision Alert, Lane Departure Warning and Side Blind Spot Alert. Check out the gallery above to see the Spark in its nuclear green paint at the New York show before the little hatch arrives at dealers in the fourth quarter of 2015.
