Tokyo world premiere for Mazda TAKERI concept
Mazda TAKERI Concept features a SKYACTIV-D diesel engine
Mazda will roll-out a new midsize sedan concept at the 42nd Tokyo Motor Show next month. The company will showcase its first regenerative braking system as part of the world premiere of the Mazda TAKERI, which is also equipped with a SKYACTIV-D diesel engine and an i-stop idling stop system.
Like the new Mazda CX-5 SUV (which was shown in Frankfurt this year but will make its Japanese debut at the Show), the TAKERI is based of Mazda's new "KODO - Soul of Motion" design language - meaning that we'll likely see styling elements of the TAKERI appear in production models down the track.
The appearance of Mazda's first regenerative braking system is notable because this car isn't a hybrid - it runs on a diesel engine. Like conventional hybrid systems, kinetic energy is captured and stored during braking, but in this case, rather than being fed back to an electric motor, the energy is stored in a capacitor and used to power the vehicle's electric equipment. This reduces engine load and results in excellent fuel economy according to Mazda.
As mentioned, the new Mazda CX-5 will also take to the stage with its full range of SKYACTIV technology. SKYACTIV is the blanket term Mazda uses to describe its next-generation technologies including two gasoline engines (1.3 and 2.0 liter), a 2.2 liter diesel engine (found on the CX-5), plus new transmissions, body and chassis.
There's no further details on the TAKERI at this stage but stay tuned - we'll be taking a closer look when doors open at the 2011 Tokyo Show.
I have long encouraged taking the auxiliary systems load of the engine, and didn\'t mind the car I drove that turned off the AC when accelerating.
Having a relatively low peak load should extend the life of the capacitor, or battery when the system hits production.
I hope the vehicle\'s electric equipment includes the power steering, AC, and water pump.
What about adding either an electric motor to the drive system to take the load from a full stop where overcoming inertia costs a huge penalty against mileage OR a mechanical system with a flywheel for the same purpose?
Like the KERS systems in use in Formula One Racing. I love the spin off technology that comes to us from this great racing platform. (If only we had a US team!).
I do mind the AC turning off at stop lights during certain situations, like when I am suited up for business and roasting. At that point I want it on full blast even if I am upside down and under water.
I love being alive during the age of technology\'s wild ride!
Hi giz mag I enjoy reading your mag a lot. Comment about the new Mazda, there are 2 massive problems with nearly all new consumer cars.
1. built to be redundant so the consumer will have to buy the next bit of crap, 2. they run a toxic diesel fuel that is now spelling mass extinction..... I drive a 1970 electric car power from the sun and wind and my transport will see this new Mazda out. We can no longer afford to take on this over complicated consumer rubbish,
This is perfect! It also reduce the extra weight to form a hybrid car! Lighter = more fuel efficient.
I hope the price wouldn\'t be ridiculous.
Mazda may be in uncharted territory with a
small diesel, capacitor charged regenerative
braking and the i-stop idling system.
This may be a less expensive and less toxic
answer to the hybrid batteries for use in cars.
A capacitor discharge for electrical starting
and acceleration from a stop and A/C use
while stopped will be a selling point.
A turbo-charger for highway speeds and
hill climbing might be a benefit too.
But it is a DIE-sel and won\'t sell in the USA.
(I would buy one if the MPGs are high !!!)
Buzz and BomR76.
You need to go back to school. Diesels are no longer the smelly, belching things they used to be. A current VW Polo gets about 90 miles to a gallon of diesel. It also burns pretty clean. You just can\'t buy one because Washington is full of self-servings interest groups and gutless politicians.
Even the US diesels that sell here are decent. Yes diesel is dirtier than gasoline. However, some cars get 40% better mileage with the diesel. I have a buddy that has a 2009 Jetta with a manual and he gets almost 50 mpg. Without having to worry about disposal of the heavy metals that make up batteries and what landfill they will go to. Much less the cost of replacement on a battery pack for a car.
This seems a strange combination of capabilities. If you can do regenerative braking by removing energy from the car\'s motion at a 30 HP rate, for example, you must already have a generator and storage mechanism (super-capacitor) capable of handling 30 hp. With only slight changes in programming/controls, this combo is a 30 hp motor. Why would you throw away an extra 30 HP in acceleration, when you already have all of the pieces in place to do this? A better combo would seem to be an engine sized 30 HP smaller, with the pervasive economies that would permit, using the regenerative braking system as a engine booster also. If not needed as an engine booster, the stored energy could always be used for automotive accessories. Am I missing something?
The disadvantages of the high discharge rate required for electromotive drive, the expense of of large electric motors, the weight and cost of the increased numbers of capacitors, and most importantly that this system is designed to pay for itself over the life of the car something none of the hybrid systems currently available will do.
Hi VoiceofReason -from buzz, I am one of the lucky few being dyslexic could never get the hang of writing and reading!!!so sorry not much good going back to school. What I have done is not use toxic oil fossil fuel for 10 years!!! Regarding batteries I have taken them to bits and they are simple, well real lead batteries can last, some with a bit of care can go for a hundred years!! So why do car batteries last only 2 or 5 years because? the batterers we buy use lead past! so the market can sell you the next bad one. batteries if you re-use the case are over 90% recoverable. We run 4 cars non on fossil fuel all carbon neutral from a 1999 Axim 100mpg to a 1966 morris ethonal gas power from veg wast
I also have taken petrol -Diesels engines to bits they are simple too. Our 1970 Land rover uses original engine re-built once runs home made bio-disel Registers nil emission at test station!! also run a home made Wommbel truck based on a 1971 Mini using a 1986 LT 6 V.W Turbo D engine chip fat. Yes V.W do make the best diesel after Toyota but they are still sorry but I think crap.... I do love new technology so I would like you to think I am not a total idiot! But we do need to know the truth. What do you think of a system change to non-profit renewable energy.. Run a ceramic engine with hemp body using fuel made at home but how would the big boys make there $$$$ now that is a problem which I gess the do not teach at school Thank you VoiceofReason
PS my 1975 EV has re-gen braking!energy from sun and wind! now if Mazda could do that I would buy one.
