Weekly Recap: Toyota wants cars to be your 'close friends' around 2020

Toyota confirmed plans this week to launch autonomous technology in its production cars around 2020. The automaker's version is called Highway Teammate, and it's one element of a broader mobility strategy that includes vehicles communicating with each other and the grid. "Toyota believes that interactions between drivers and cars should mirror those between close friends who share a common purpose, sometimes watching over each other and sometimes helping each other out," the company said in a statement. That sounds utopian, and perhaps a bit cheesy, but it's an acknowledgment that autonomous driving requires more than technology developed in a vacuum. Toyota is looking at its research in a broader context, and dubs its overall strategy the Mobility Teammate Concept. Highway Teammate is the first step. Its test vehicle is a modified Lexus GS, which uses road-mapping data and external sensors to merge or exit highways, change lanes, and maintain safe distances during driving. It's operated on the Shuto Expressway in Tokyo. Toyota has been working on autonomous tech since the 1990s, with the goal of providing mobility for older people and the disabled, as well as lowering the frequency of traffic accidents. Toyota's push comes as an early adopter, Nissan, is hedging on its own deadline to implement the autonomous tech by 2020 due to a lack of firm laws governing self-driving cars around the world. Conversely, Volvo took the landmark step of being the first automaker to accept liability for when its cars will operate in autonomous mode, and urged the US government to set federal guidelines to regulate the technology. OTHER NEWS & NOTES 2016 BMW M4 GTS: Your water-injected, turbo-boosted demon BMW is unleashing its most powerful M4 ever, a 493-horsepower special edition that's road legal yet bred for the track. The company is making 700 copies for sale around the world, and 300 of them will come to the United States. The twin-turbocharged 3.0-liter six-cylinder revs to 7,600 rpm and uses a water-injection technology to cool the intake air and lower the compression temperature. BMW says this allows it to wring more power out of the inline six. The car also uses carbon-fiber reinforced plastic for the roof, hood, engine compartment strut brace, drive shaft, and rear spoiler to reduce weight. The M4 features BMW's organic light-emitting diode taillights, which are said to be an industry first.

New Zealand's Taupo circuit renamed after Bruce McLaren

New Zealand's most prominent racing circuit is being renamed after one of the country's most prominent racing drivers and constructors. That, of course, would be one Bruce McLaren, founder of the racing team and supercar manufacturer that bears his name, and an accomplished driver in his own right. Previously known as Taupo Motorsport Park (after the town where it's located), the Bruce McLaren Motorsport Park is the only circuit in New Zealand certified to FIA Grade 2. The complex started out as a shorter track of 0.87 miles, and was overhauled in 2006 to its current layout at the cost of over $8 million. It hosted A1GP races in 2007-09, and still brings in various touring car, GT, drifting, and superbike events. Current F1 driver and reigning Le Mans winner Nico Hulkenberg set the lap record around the circuit's 2.17 miles and 14 turns at 1:14.072 on his way to the checkered flag in 2007 A1GP race there and the championship title that season. The renaming of the circuit was undertaken with the blessing of Bruce's widow Patricia and daughter Amanda. Their late husband and father won four Formula One grands prix, the 24 Hours of Le Mans in 1968, and two Can-Am championships. And those are just his own personal achievements as a racing driver. The cars that bear his name have won 182 grands prix, eight F1 constructors' championships, and twelve drivers' championships, plus five consecutive Can-Am titles, three Indianapolis 500 victories, a Le Mans win in 1995, and a smattering of other accolades. Bruce McLaren sadly perished at the age of 32 in a Can-Am crash at Goodwood in 1970, but as you can plainly see, his name lives on as a veritable racing legend.

McLaren and Alonso will use Chevy engines at Indy 500

Fernando Alonso will have a Chevrolet engine in his McLaren when the double Formula One champion attempts to win next year's Indianapolis 500 in his second attempt, the British team announced on Tuesday. The 37-year-old Spaniard led 27 laps last year on his debut at The Brickyard in a Honda-powered Andretti Autosport car before retiring with an engine problem with 21 laps to go. The 2018 Indy 500 winner, Australian Will Power, won with Chevrolet-powered Team Penske last May. "Having Chevrolet power behind me means we're putting ourselves in the best possible position to compete at the front," said Alonso in a McLaren statement. The double Monaco Grand Prix winner, who won the Le Mans 24 Hours with Toyota this year, left Formula One at the end of the season last month and is targeting Indianapolis as the final part of the "Triple Crown of Motorsport": winning the Formula One championship (or Monaco), Le Mans and the Indy 500. The late Briton Graham Hill, also a two-times Formula One champion who died in 1975, is the only one to have done it, completing the triple in 1972.Reporting by Alan BaldwinRelated Video: Motorsports Chevrolet McLaren Racing Vehicles IndyCar
