The return of real Japanese innovation

Hilton Holloway
Last week I spent two days in Berlin with Mazda getting an intensely detailed low down on the mechanical building blocks that will underpin the vast majority of its future models. We even managed to spend two hours sampling Mazda’s new engines and transmissions on the German roads, which were bolted into an early version of Mazda’s clever new platform.

And yesterday I returned from an intense briefing on Mazda’s new design philosophy and the unveiling of the stunning Shinari concept car - which is a clear hint at the shape of the all-new, 2012, Mazda 6.



Mazda’s long relationship with Ford is being slowly unwound and the car maker’s finest minds have sat down and thought very long and very hard about how a comparatively small independent company (which makes a varied 1.2 million vehicles per year) can survive in the global market.

I’m convinced that Mazda’s design and engineering teams have cooked up a solution that’s so clever and so brilliantly engineered that the rest of the car industry will look on in admiration.

Mazda’s future is based around just a single scalable steel spaceframe platform, two basic (but completely re-thought) petrol and diesel engine designs, and manual and auto transmissions.

The programme kicks off with a 2.2-litre diesel engine that not only has an low 14:1 compression ratio, but can also meet super-strict Euro 6 pollution regulations without a NOx trap and is even cheaper to build than today’s Euro 5 diesel engines. Hooked up to a six-speed manual ‘box, this engine - when fitted in the next-gen Mazda 6 - promises a CO2 output of just 105g/km. And that’s without any of the clever fuel saving devices fitted to, say, an Efficient Dynamics BMW 3-series.

The new 2.0-litre petrol engine is (unusually in these days of forced induction) normally aspirated and runs an unusually high 14:1 compression ratio. Mazda has been aiming for a beefy torque curve, smooth manners and impressively low consumption.

It has also thought outside the box with the new platform, which makes use of simple box-section pressings under the floor and super-strong ‘ring’ structures for the upper part of the platform. This relatively simple construction will be able to be scaled down to the Mazda 3 and up to the US-market CX-9.

Mazda engineers are also working hard to make the chassis much more in tune with European tastes, tuning out the high-pitch road noise and resonance that the Japanese ear doesn’t find a problem with, and giving the chassis a much firmer and more stable feel at motorway speeds.

Having sampled both engines and both transmissions in the new platform I’d say - even 20 months out from production - that Mazda is a long way towards achieving its goal.

Of course, all this superb effort needs to be clad in an eye-catching skin. Typical contemporary Japanese styling won’t do.

Which is why Mazda showed us the Shinari concept, a very strong hint towards the form of the new Mazda 6.  In the late summer light of Milan, this car was a genuine stunner. The interior (led by an ex-Audi designer) is exceptional, especially the cockpit and switchgear design.

Of course, a production version of  this car would have to have at least a taller glass house and real bumpers. But if Mazda can get near turning this 6 mule into something approaching the Shinari, it will have pulled off an engineering and visual coup.

I don't fully understand the title of this article..."The return of real Japanese innovation"? These days, Japanese car makers aren't comprised of just Japanese people...for instance, the Furai and Nagare were designed by someone called Franz von Holzhausen...

Mazda also have an R&D centre in Europe, as do most of the Asian brands (if I'm not mistaken Toyota, Nissan, Kia etc also have design and research centres in Europe)...so most probably these new designs and engines are highly influenced by European designers and engineers too.

Nevertheless, the engines sound promising...although I'm also quite keen on the type of engine combining the best of petrol and diesel, such as Merc's DiesOtto engine; on a car the size of the S-Class, a 1.8-litre engine is enough to accelerate it from 0-60mph in under 8 seconds while achieving over 50mpg and 127g of CO2/km (and this is technology of 3 years ago)...it will be interesting to see how these technologies (Mazda's new engines and DiesOtto) shape up.

It all sounds very positive and very like Mazda to go it alone.

I actually like the styling of the current European Mazda 6 - on the lower spec cars where you have a blacked out grill - rather than the "sports" spec car in the picture.

What capacity are they talking about for the other petrol engine? Mazda have a very large range of car sizes (obviously) from the 2 right up to the CX-9 - currently they use a 1.3, 1.5, 1.6 (ford), 2.0, 2.3 turbo, 2.5, 3.6 (ford) - perhaps for the smaller vehicles they'll just bring in engines from another manufacturer?

Prompted by your praise I took another look at the Shinari's interior. (Boy, how that advert annoys suddenly flipping out of view interior pics from exterior!)

The interior has shades of TVR in its design, dare I say it, although one supposes better constructed. There is a fine mixture of adventurous architecture, switch hear innovation, and pure simplicity. Very commendable.

Sounds good. Just read a review of the 2.2 diesel and am impressed by the torque. How they achieved 14:1 compression-ratio with a diesel is worthy of investigation..

I don't want one with a taller glasshouse - I never wear a hat when I'm driving.

When you say "return" of real Japanese innovation,

was there ever any in the first place?

Apparently Mazda decided not to downsize the 2.0l petrol because they believe that when HCCI becomes a reality in a couple of years time, everyone will be reverting to "normal" sized engines again, without the expense of turbos.

And apparently the diesel runs such a low compression ratio to reduce friction, thus making it more efficient, but if that's true why doesn't everyone do this?

theonlydt September 2, 2010 11:06 PM

Honda use a low compression ratio in their DTEC diesel and touted the use of a low compression ratio for the same reasons - though apparently another reason was the all aluminium block, despite being stronger than most due to a unique manufacturing method, wouldn't like higher compression ratios.

As Mazda have had a large design input into the latest generation of Ford petrol engines are they planning all of this for themselves or planning to sell it to other manufacturers?

Perhaps they could go back to wet liners for their high compression approach. I alwyas thought the French and Italians did a lot with these and now that everyone takes a sealed approach to cooling systems the poor maintenance issues should be manageable.

Never mind this Mazda, real innovation is coming.  A Japanese firm is making a fast charger for Electric Cars that will give an 80% recharge on a Nissan Leaf in just 6 minutes!  So to all thos doubters, you will get about 150 mile range in 6 minutes, thats sounds like progress to me.
