The 2017 Hyundai Ioniq fuel economy numbers are official, and impressive

Thanks to the EPA's handy fuel economy reference site, fueleconomy.gov, we now know exactly how the three versions of the 2017 Hyundai Ioniq did in fuel economy testing. The EPA tested all three versions: the hybrid Ioniq, the plug-in hybrid Ioniq Blue, and the self-explanatory Ioniq Electric. For reference, the 2017 Toyota Prius is no slouch, getting 50 mpg highway, 54 in the city, and 52 combined according to EPA testing. Now let's compare to the Ioniq, which in regular form gets 54 highway, 55 city, and 55 combined. It bests the traditional hybrid Prius most significantly on the highway. The plug-in Blue achieved 59 highway, 57 city, for a combined 58 mpg rating. As we mentioned in our earlier deep dive on the Ioniq range, the plug-in will also do 31 miles on electricity alone. As suspected, the range of the Ioniq Electric is going to be an issue for the company. The EPA confirmed the range to be 124 miles in total, returning an MPGe rating of 122 highway, 150 city, and 136 combined. We know that Hyundai is self-conscious of the range of the initial model, which looks unimpressive compared to the crop of 200-plus-mile range EVs coming to market soon, like the Bolt. Hyundai recently told Automotive News that a 200-mile range version will be coming quickly, by 2018, so the Electric won't be hobbled for too long. As long as we're comparing it to the Bolt, it should be noted that the MPGe numbers are better, even if the total range isn't. The Bolt is only good for 110 highway, 128 city, and 119 combined MPGe – to put it another way, the Ioniq Electric consumes 25 kWh per 100 miles, while the Bolt consumes 28. A small difference, to be sure, but worth noting. Don't forget that there's a fourth Ioniq out there, which we rode in recently, although it's notably mainly for its autonomous tech rather than its drivetrain.

Hyundai CVVD engine brings another dimension to valve timing

A new technology from Hyundai Motor Group places another marker on the march to more efficient internal combustion engines. Called Continuously Variable Valve Duration, the innovation permits two options for how long the intake valves remain open during the combustion cycle. The feature adds a third take on valve chicanery, atop variable valve timing that changes when valves open, and variable valve lift that changes how far valves open. Hyundai says the feature returns a 4% improvement in performance, a 5% increase in fuel economy, and lowers emissions by 12%. Hyundai applied for two patents on the valvetrain process in South Korea in 2011 and again in 2015. The altered valve duration in this latest iteration is made possible by two movable arms inside the camshaft. Each arm is anchored at its base to a pin at the center of the camshaft, while the end of each arm extends toward the edge of the camshaft. Changing the position of the pin in the center of the camshaft changes the angle of the arms relative to one another, which moves the camshaft along its mounting rod. Voila, a new intake cam profile that either lengthens or shortens valve overlap.   During low-speed spells at low load, CVVD opens the intake valve from the middle to the end of compression stroke. The weaker detonation isn't a factor at low load, and the reduced friction during compression improves fuel economy. During heavy engine loads, the intake valve closes at the beginning of the compression stroke to maximize the amount of air mixed for detonation, boosting torque. Four additional features enhance the benefits of CVVD. A more powerful direct injection system increases fuel spray pressure from 250 bar to 350 bar. Hyundai doesn't go into details on its Integrated Thermal Management System, but says the ITMS "quickly heats or cools the engine to the optimal temperature." Low-friction components lower overall engine friction by 34 percent. And a low-pressure exhaust gas recirculation layout diverts low-pressure exhaust gas from the traditional EGR route to the turbocharger compressor under high load for better fuel efficiency.   The first engine to boast the new tech is the Smartstream G1.6 T-GDi four-cylinder, which produces 180 horsepower and 195 pound-feet of torque. It will appear in the 2020 Hyundai Sonata Turbo going on sale in South Korea later this year.

Recharge Wrap-up: Rimac Concept One vs. Bugatti Veyron, Tesla Autpoilot in the snow

Watch the Rimac Concept_One and the Bugatti Veyron drive head-to-head along the Croatian coast. Rimac Automobili founder Mate Rimac invited the Earl of Pembroke to drive his 1,088-horsepower EV, while he'd drive Lord Pembroke's Bugatti for comparison. Besides the scenic coastal roads shown in this first film, the pair also drove on a racetrack and an airfield. More episodes – and a drag race – are to come. Watch the video above, and read more at Teslarati. Watch how Tesla Autosteer operates in the snow at night, with no lane markings and no lead vehicle. While Tesla doesn't recommend using Autopilot in these conditions, it seems to manage rather well. Even thought the system shows that it doesn't always recognize the curb, the car doesn't instruct the driver to take control. It's possible that data plays a key role when there aren't other guiding factors on the road, and Tesla's high resolution mapping and the car's GPS could help navigate when there is little sensor input.

Andromeda Power uses its V2V Orca Inceptive onboard charger, which is meant for CHAdeMO to CHAdeMO charging. It requires a lot of equipment, including a CHAdeMO Tesla adapter, but it's definitely one way to feed a Tesla enough juice to get to the nearest charging station. Read more at Inside EVs. Hyundai increase the range of its Tucson Fuel Cell by 30 percent. The next generation of the hydrogen powered Hyundai is expected in early 2018, and range will jump from 265 miles on a full tank to 348 miles. That surpasses the Toyota Mirai's 312-mile range, but not the 366 miles of the Honda Clarity Fuel Cell. Read more at Green Car Reports, or from the Nikkei Asian Review.
