BMW's plans for a high-tech eco supercar has been revealed in the form of the BMW Z10 ED, a two-seat production of Technik division and will be the flagship of the company. The supercar is intended to highlight the latest drivetrains, electronic technologies, body architecture and auxiliary parts. The suffix "ED" stands for Efficient Dynamics which is BMW's lineup of fuel-saving technologies that also reduce emissions of carbon.
Tested and proven technology on the Z10 will be adopted by volume models in the next ten years. The Z10 will be produced in restricted numbers and will sell at an estimated £80,000. Initially planned as a one-off concept, plans were later switched to focus on greener car when BMW bosses abandoned the plan last year for a V10-powered mid-engined competitor to the Audi R8.
Speaking of the Z10, BMW representatives explain: "The idea is to bring all the very latest technology together in a way that will allow a high level of performance without overburdening the environment in a way that the current crop of supercars do."
Utilizing BMW's carbon fiber construction expertise together with the wide-ranging use of aluminum chassis components, the Z10 will not exceed 1,400kg in overall weight. The engineers of BMW have found a way and have actually patented a process that merges multiple parts into a single sub-assembly. Exploration of built-in door frames and sill panels for the Z10 is also in BMW's agenda, a decision designed to guarantee low curb weight and high bodyshell rigidity.
The Z10 ED will also be used to showcase BMW's downsizing plans considering the possibility of producing powerplants with smaller footprints, without sacrificing performance, by taking advantage of recent developments turbocharging, direct injection and thermal technology. Engines being considered for the hybrid include a brand new high-pressure turbocharged direct-injection straight six which will replace the current 3.0-liter engine that's being employed across the BMW range.
This motor comes in two guises; one utilizes a standard mechanical valve system in conjunction with double VANOS variable valve timing system, and the other features electronic valve control that permits variable compression ratio.
The new engine can be expected to deliver in the neighborhood of 400 hp with the latest BMW 7-speed dual-clutch gear in combination with stop-start technology, a built-in starter/generator and a enhanced version of the current brake energy regeneration system, thus adding 15 percent boost on efficiency. The brake energy regeneration system will be revised to store energy in an extra lithium-ion battery.
