Honda CR-Z finally revealed in full

Having been the subject of brochure leaks and other sneak previews for many months now, Honda's hybrid CR-Z has finally been officially unveiled at the Detroit motor show.

The production car, though less dramatic than the concept, still looks great and remains remarkably close to the original design. Sharing styling cues with both the first and second-generation Insight hybrids and the first two generations of CRX, Honda claims that the car will be great fun to drive despite its modest power output of 122bhp and 128lb/ft of torque (at a low 1000-1500rpm). All this is provided by a 1.5 litre VTEC four-cylinder with Honda's IMA (Integrated Motor Assist) hybrid system.

The 60mph from rest benchmark comes up in just under ten seconds - not a figure that will set the world alight, but enough in a compact and lightweight hatch to have some fun, especially on UK roads. Honda's intentions for a great drive are spoken loudly by their decision to offer a six-speed manual transmission as well as the CVT typical of normal hybrids, and the CVT itself offers a paddle-shift mode. As with many modern cars with "sporting" intentions, the CR-Z offers a three-mode drive system with normal, sport and economy settings.

Economy on America's EPA cycle is estimated (in UK gallons) at 43mpg city and 46mpg highway for the CVT model and 37mpg/44mpg for the manual transmission, though this is of course determined by whether you choose to drive it like a hot hatch or like a hybrid...

The CR-Z is expected to go on sale in the Summer. If there's one car that Tarmac test drives this year, the CR-Z will be it! (Yes, those promised drives will start happening eventually...)

Tommy Kaira hybrids

Japanese car tuning and manufacturing firm Tommy Kaira have now turned their attention to hybrids, it seems, in a break from their normal line of hot Nissans. In contrast to the wild GT-Rs, Skylines and Z-cars that usually benefit from Tommy Kaira's body and engine upgrades, the Toyota Prius 3 and Honda Insight might seem a little tame, but the big wheels, beefy exhausts and squat stance used rather suits the shape of each car - especially the Insight.

Of course, one has to question the motive for performance tuning on hybrids. When manufacturers have spent so long perfecting aerodynamic shapes in wind tunnels and choosing low-rolling resistance wheels and tyres, it seems nonsensical to take several steps back by increasing drag and resistance with kits like these.

You also have to wonder who'd actually buy the kits. I certainly can't see them being popular with the Ecomodding crowd, and many car "enthusiasts" seem to take a dim view of hybrids, expecting they'll spell doom and gloom for performance motoring, so there doesn't seem to be an obvious market there earlier.

But of course, the main market is in Tommy Kaira's native Japan, where customers aren't beyond tuning tiny Kei cars, let alone relatively powerful hybrids. Perhaps there, where aerodynamics have little effect in inner-city traffic, the draw of a tuned hybrid is much greater.

And of course, a belated happy New Year to all Tarmac's readers. Best wishes for 2010!

Most frugal car in the real world? Autocar finds out with a race...

Manufacturers make big claims about their fuel economy figures. Occasionally, even these claims can be bettered, as Toyota's now closed blog for the iQ managed back in January, extracting 72mpg when Toyota themselves only claimed 65mpg. Often though, real-world driving prevents us from extracting the optimum economy from our cars.

Autocar's test then perhaps sheds a little more relevance on achieving high miles to the gallon. Armed with a Ford Fiesta Econetic, a Vauxhall Corsa Ecoflex, an Insight, a Prius, a BMW 116d and a Smart ForTwo CDi, they each hit the track at Bruntingthorpe with a single litre of fuel and a driver trying to achieve as many miles in the hour as possible. By working to distance rather than outright economy, it avoided the whole race becoming a slow eco-trundle.

The most efficient at the end of the hour? Ford's Fiesta Econetic. It achieved almost sixty miles at the hands of Matt Prior, equivalent - unsurprisingly - to roughly 60mpg. A little way short of Ford's 76mpg combined figure perhaps, but much more representative of what drivers can expect in their daily grind, and a long way from shabby.

The other cars in the test all managed to average around 55mpg, including the diminutive Smart despite being driven pedal-to-the-metal until it spluttered to a halt after 53 minutes.

80mpg from diesel-powered first-gen Insight

Yes, you read that correctly. AutoBlogGreen has released news that a company called Red Light Racing has installed Volkswagen's 1.2 litre, 3-cylinder Pumpe Düse TDI in a first-generation Honda Insight and the net result is 80mpg in US gallons - a staggering 96mpg imperial.

The engine has been taken from Volkswagen's Lupo 3L, a model that was only available in mainland Europe and itself made 94mpg imperial, equivalent to 3 litres/100km. The Lupo however was solely diesel-powered - and Red Light Racing state that they haven't even hooked up the Insight's hybrid motor to the diesel unit yet and once they do there could be another 15-20% improvement.

The Lupo 3L was highly modified from the standard Lupo TDI - like the Insight, it used aluminium in much of its construction, and also in common with the Insight it used low rolling-resistance tyres and a stop-start function to save fuel when stopped in traffic. The engine produces 61bhp and makes 140Nm of torque, which is 9bhp less than the Insight's 1.0 litre petrol IMA unit but a useful 27Nm more torque. Coincidentally, both Lupo 3L and Insight weigh in the region of 850kg, so the engine seems ideal for use in the Insight, though according to Red Light Racing the installation naturally wasn't too straightforward.

Diesel clatter aside, the new engine should provide very pleasant driving characteristics too. The final quote goes to Red Light Racing, clearly a company after Tarmac's heart: "The main idea was to take existing hardware, hack it, and make a vehicle that could be produced by major manufacturers or individuals that would deliver tremendous fuel economy without a tremendous leap in technology. I believe we succeeded."
