Lucid Air and Maserati MC20 unveiled | Autoblog Podcast #644

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Byron Hurd. Before they get to the juicy news of the week, they chat about the cars they've been driving, including a Ford Mustang Shelby GT350R, Audi A6 Allroad, Mazda CX-9 and Kia Niro. It's been a busy week in the news department, with GM investing in Nikola, Lucid Motors launching the Air electric sedan, Maserati unveiling the MC20 mid-engined supercar and a farewell to the Lexus GS. Then they talk about having a newfound respect for the Fox Body Mustang and the Mazda CX-9.

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.

Good Samaritans rescue driver from sinking car in Florida

A pair of good Samaritans and three police detectives saved an elderly Florida man from drowning in his car after it crashed into a pond this week. According to Port Saint Lucie police, Hixford Banton was traveling westbound along Port Saint Lucie Boulevard in Port Saint Lucie when his Mercedes sedan was struck by another motorist attempting a turn on to the street from Arioso Boulevard. The collision caused Banton to lose control of his Mercedes. In his confusion, he ran off the road, drove across a lawn, and crashed into a pond in front of the town's City Hall. James "Randy" Brazier was across the street when he heard tires screeching, and turned to see Banton's Mercedes go into the pond. He rushed across the busy street, jumped into the pond, and swam to the rapidly sinking Mercedes to save the driver. Once Brazier reached the car and opened the door, it immediately capsized and sank to the bottom of the pond. "When I got to the guy, he was real scared, so I told him to calm down, " Brazier told the TCPalm newspaper. "I opened the door and got him out, he panicked, took us both under and then I hit the bottom, pushed ourselves back up." Brazier was assisted by another passerby named Charles Proulx, who waded into the pond to help the struggling men. Three Port Saint Lucie police detectives–Stephen Reuther, Peter Chunn, and Maiga Auguste–arrived soon after with a rescue ring and helped to pull the men out of the pond. Once everyone was ashore, salvage divers were brought in to locate the car and pull it out of the pond. Thanks to the murky water and the pond's surprising depth, roughly fifteen feet, it took divers nearly thirty minutes to locate the car. Later, at the police station, Banton said that he had yet to meet his rescuer. "Somebody I have yet to meet came in and helped me. He came to me and he said, 'I got you, I got you, are you ready?'" Banton said. "And he opened the door, and I just went out." Banton also stated that he could not swim, and that he would have died had Brazier not come to his aid. Soon after, the two were reintroduced under less stressful circumstances. News Source: TCPalm, Palm Beach Post, WPBF Government/Legal Weird Car News Kia Driving Safety Autoblog Minute accident
