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.

BMW X4 hatches its fastback shape in Shanghai

The day has finally come for BMW to pull the covers off its X4 Concept at the Shanghai Motor Show. The machine brings few surprises - we've already seen an official image gallery from the German automaker, so its exterior shape was well known - but at least now we get to see it with our own eyes, and with the lenses of our very own cameras.
You can clearly see the fastback roofline in our high-res image gallery above, along with the jacked-up stance that allows BMW to call this machine a Sports Activity Vehicle, which basically means "Crossover" to our friends in Munich. We've seen similar vehicle shapes before, most notably in the form of the BMW X6, but also as far back as the 1980s from the likes of AMC.
We fully expect the transition from concept to production to be pretty seamless, so what we see here is, for the most part, what we'll see on the showroom floor in 2014. Feel free to peruse the press release below, but first, be sure to browse through our live images from Shanghai and let us know what you think.

Ex-Rolls-Royce design chief Ian Cameron killed at home

Former Rolls-Royce design chief Ian Cameron, the man who oversaw the automaker's design renaissance with the Phantom and Ghost ranges, was stabbed to death at his home in Bavaria (translated) on July 12. German newspaper reports have identified a suspect via surveillance camera (translated) whom police say is the killer. Apparently, the man went shopping at a store less than a mile from Cameron's house, then changed clothes and showed up at Cameron's door. A surveillance image before the suspect gets to the house shows him wearing the items that neighbors described, notably light pants, a dark blue hoodie, a red backpack and "yellow-green gloves." Someone reportedly cut the wires on the home security system, the suggestion being that the suspect or someone else involved had cased the house for at least a few days. It's said the killer rang the doorbell, attacking as soon as Cameron opened the front door, stabbing the designer to death. Verena Kloos, Cameron's wife, escaped to a neighbor's house and called police. This is a bizarre incident. Reports have floated the motivation that the killer wanted one of the vehicles in Cameron's car collection at the Bavarian property. Instead of going after a car, though, the killer ran off in his distinctive outfit, staying in the open long enough for neighbors to give a detailed description. He then changed clothes and ditched the backpack on a lakeside promenade not far from Cameron's house. Strangest of all, the man apparently left the clothes near the backpack, and the backpack contained items the man had bought during his shopping trip before the murder.  At the time of writing, police are searching throughout Germany but haven't caught the suspect. With a clear picture and a likely trove of DNA evidence, authorities have excellent leads. Anyone who can help is asked to get in touch with the Furstenfeldbruck Criminal Investigation Department at (+49) 8.14.16.120. Cameron's career started at Pininfarina in 1975, culminating in a greatest hits of designs while at BMW. He has exterior design of the third-generation Range Rover on his resume, as well as the BMW Z8. It was Cameron's Phantom, though, that helped create an entirely new Rolls-Royce after BMW bought the brand. CEO Chris Brownridge wrote on LinkedIn that "Ian played a significant role in shaping Rolls-Royce from when it was first acquired by BMW Group and moved to its home at Goodwood, West Sussex.
