BMW mulled ten, eight, and six-cylinder engines for i8 before going hybrid

There's little doubt that the 2015 BMW i8 is one of the most radical and groundbreaking performance cars this industry has seen in a long time. From its unique carbon-intensive construction to its 1.5-liter, three-cylinder and electric motor plug-in powertrain to its concept-car appearance, the flagbearer for BMW's new i venture challenges the very notion of what it takes to be a supercar.
Yet apparently the i8 almost didn't do that at all. Yes, it probably still would've had innovative assembly techniques, serious performance and come-hither bodywork, but according to a new report in the Telegraaf, it was very nearly a much more conventional beast, drawing its power from a V10 engine. According to the report, that line of development never got much beyond the drawing board, but BMW engineers then shifted their focus to both V8 and six-cylinder motivation, going so far as to build prototype cars. The higher cylinder-count engines were eventually dropped altogether after BMW decided to turn the i8 into a hybrid, with the six-cylinder reportedly nixed due to heat management and weight issues. In the end, of course, BMW went with the PHEV powertrain that offers a total system output of 362 horsepower and 420 pound-feet of torque - plenty of thrust for this lightweight, all-wheel drive coupe while still enabling an incredible 94 miles to the gallon on the EU cycle. Regardless of how it turned out, it's still fascinating to think that BMW didn't have a much firmer conceptual idea of what it was after when it started the i8's development.
Here at Autoblog, we're genuinely thrilled about this new generation of greener hybrid super- and hypercars, a movement spearheaded by the i8, Porsche 918 Spyder, Ferrari LaFerrari and McLaren P1. But even so, our inner-gearheads can't help but wonder what might have been had BMW pursued a more conventional i8, either in place of, or in addition to, the car they did build. What do you think?

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.

Recharge Wrap-up: EVSR returns to Mt. Washington, China Mulls $16 Billion For EV Charging

Foxconn and electric carmaker BAIC are partnering to provide an electric car rental service in China. Slated to kick off next month in Beijing, Hangzhou and Jiangsu province, the company, called Henyu, will offer the EV rentals by the hour. Henyu hopes to offer 5,000, to 10,000 electric rental cars within a year, and wants to become the largest EV rental group in China. The company will also deploy BAIC's E150EV to ten cities for rental outside of Beijing. Read more at Want China Times. Hoping to convince more people to make the switch to electric cars, China is considering investing $16 billion to install charging facilities. Anonymous sources have said that an announcement about the program will be made soon. China has already announced and implemented various measures, such as incentives and tax breaks, to encourage more people to drive emissions free and improve urban air quality. China aims to have 30 percent of its government vehicle purchases be EVs by 2016, with higher targets after that. There's more from Bloomberg. BMW is launching a campaign to highlight technology features from the i8 to be used in other BMW vehicles. Called BMW Innovations, the program will include television ads showing how the i8's full-color heads-up display, LED headlight technology and Surround View Camera System are making their way into cars such as the 3 Series, 5 Series and X3, respectively. BMW Innovations also includes digital and social media campaigns, as well as hands-on technology presentations at dealerships. See the new ads below, and learn more in the press release. EVSR is set to return to Mt. Washington for the Alternate Energy Summit. It is the team's first time back since EVSR set the electric vehicle record at the Climb to the Clouds hill climb earlier this year. EVSR will run the cars up the hill again, and it will hold a workshop about electric racing, called "Redefining Motorsports - A How-To Guide for Creating a Revolution in Speed." The Alternative Energy Summit takes place on September 13 and 14 as part of National Drive Electric Week, and is free to the public. Read more in the press release, below.
