Supra successor may be all-electric sourced from Tesla; MR2 returning too?

Rumors of a revival of the Toyota Supra and MR2 have been swirling for years right up until just this week when high-level Toyota employees all but confirmed their return.
But now The Detroit Bureau has put together news from different sources suggesting that the next Supra might be all electric. The report cites recent comments from Toyota senior executives hinting at plans to work with Tesla on a new joint project. The FT-HS Concept (shown above) seems a logical inspiration for a new Supra.
And on the other side of the equation is Tesla's design chief Franz von Holzhausen who was quoted last year saying his company was looking at its next project, probably a sports car, that would follow next year's intro of the Model X. He went on to suggest the car would compete directly with BMW's 3 Series, which, in coupe form, could be a worthy competitor to a Supra as well.

Recharge Wrap-up: Ferrock a carbon-negative cement substitute, Audi makes e-diesel

A cement alternative uses recycled materials and traps CO2 rather than producing it. Invented by David Stone at the University of Arizona, Ferrock uses recycled steel dust and glass to produce a substance stronger than conventional concrete. Cement has a high carbon footprint from the high heat needed to process the limestone. Ferrock needs no such heat, and it actually uses CO2 to harden, making it, as Stone calls it, a carbon-negative material.

Part of the Firmware 6.2 update, Valet Mode allows the owner to disable certain performance features and block personal information when letting someone else drive the car. It limits the car's to speed to 70 miles per hour, and caps output at 80 kW. It can also disable mobile app access, Homelink, Bluetooth and wifi and the "Places" function, which stores addresses for you. The folks at Teslarati did find some shortcomings in the new feature, though. Read more at Teslarati. Audi has produced its first batch of e-diesel made from water and CO2. The fuel is made by reacting hydrogen from the water with CO2 to make long-chain hydrocarbon compounds called "blue crude." That can then be refined similarly to crude oil to make e-diesel, which is a fuel free from sulfur and aromatic hydrocarbons. That e-diesel can be used on its own, or mixed with fossil fuel diesel to power a vehicle. "In developing Audi e-diesel we are promoting another fuel based on CO2 that will allow long-distance mobility with virtually no impact on the climate," says Audi Head of Sustainable Product Development Reiner Mangold.

Fuel of the future: Research facility in Dresden produces first batch of Audi e-diesel - The verdict: Pilot plant produces high-quality diesel fuel - No need for mineral oil: e-diesel made from water, CO2 and green power - Minister Wanka: "Synthetic diesel using CO2 is a huge success" Audi has taken another big step in the development of new, CO2 neutral fuels: A pilot plant in Dresden has started production of the synthetic fuel Audi e diesel. After a commissioning phase of just four months, the research facility in Dresden started producing its first batches of high-quality diesel fuel a few days ago. To demonstrate its suitability for everyday use, Federal Minister of Education and Research Prof.

If Tesla Model 3 is successful, Sergio Marchionne will copy it

Fiat Chrysler CEO Sergio Marchionne hasn't hidden his disdain for electric vehicles, but he would copy the Tesla Model 3 if it is successful, according to Automotive News Europe. If Elon Musk "can show me that the car will be profitable at that price, I will copy the formula, add the Italian design flair and get it to the market within 12 months," Marchionne told Automotive News Europe during FCA's annual meeting in Amsterdam. In terms of pre-orders, the Model 3 is a success. Musk tweeted on April 7 that the company had over 325,000 reservations for the sedan, which he estimated were worth around $14 billion. The car will start at $35,000 before incentives. Marchionne, however, isn't optimistic Tesla can actually make the electric sedan work financially. "I'm am not surprised by the high number of reservations but you have then to build and deliver them and also be profitable," he told ANE. The FCA boss is a noted skeptic of EVs. In 2012, he said that the company only built the 500e because of California's zero-emissions vehicle mandate and to give engineers experience with the technology. He doubled-down in 2014 when he claimed FCA lost $14,000 on each 500e and said he would rather people didn't buy them. More recently, he infamously said "you'd have to shoot me first," before he'd allow a fully electric Ferrari. Related Video:
