McLaren teases roaring new 675LT ahead of Geneva debut

McLaren is set to reveal the new 675LT at the upcoming Geneva Motor Show, but before it does, the F1 team turned exotic automaker has been peppering us with teasers of the new track-focused supercar. The 675LT promises a raft of enhancements over the 650S on which it's based, starting with the engine: McLaren's ubiquitous 3.8-liter twin-turbo V8 has been fitted with lightweight components and new turbo spools to drive output up to 666 horsepower (675 in metric terms, hence the first part of the nameplate) and 516 pound-feet of torque. It also gets revised bodywork with a longer tail (hence the LT) that helps produce 40 percent more downforce, and a dual-tip titanium exhaust. We'll have more on the new McLaren 675LT as its debut approaches less than a month from now, when it will form part of the brand's newly aligned Super Series (alongside the 650S and Asian-market 625C) above the upcoming entry-level Sports Series. But in the meantime, you can hear that upgraded engine roar through the new exhaust in the video clip above. AERODYNAMICALLY OPTIMISED, THE McLAREN 675LT STAYS TRUE TO THE ICON - Active 'Longtail' Airbrake contributes to a 40 percent increase in overall downforce - 700 Nm (516 lb ft) produced by a heavily revised 3.8-litre twin turbo V8 featuring lightweight components and new turbos - Bespoke titanium crossover exhaust ensures optimised performance. See, and hear, it at: http://youtu.be/tOl7gZ8bQdY The 675LT, the first McLaren in nearly two decades to wear the LT – or 'Longtail' – name, will stay true to the spirit of its iconic predecessor with aerodynamically optimised, dramatically enhanced styling that results in 40 percent more downforce than the 650S which it will sit alongside in the McLaren Super Series. A total power output of 675PS (666bhp), and torque figure of 700 Nm (516 lb ft) plus a focus on weight saving will ensure an electrifying, engaging and visceral driving experience. These output figures are produced by a heavily revised 3.8-litre twin turbo V8 featuring lightweight components and new turbos. A controlled torque delivery of 600Nm (443 lb ft) ensures optimised acceleration and traction from a standing start in first gear, rising to the full 700Nm available from 5,500-6,500 rpm, through each of the other gears. A redesigned crossover exhaust system, bespoke to the 675LT, is formed from lightweight titanium. Two circular titanium exhaust pipes exit centrally through exposed bodywork below the rear 'Longtail' Airbrake.

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.
