Kia Motors is about to launch its first ever global hybrid car with the introduction of the Optima Hybrid into the U.S market next month.
The Optima Hybrid uses a Kia-developed powertrain with lithium polymer batteries that won’t need replacing for up to ten years or 240,000kms.
The Optima Hybrid will be a full parallel hybrid vehicle with its 2.4-litre GDi direct injection petrol engine mated to a small electric motor driving the front wheels via a six-speed automatic transmission. A special clutch is fitted between the engine and motor, enabling the petrol engine to be de-coupled from the powertrain so that Optima can be operated in zero-emission, full-electric drive mode from standstill up to 100km/h ( 9.2 seconds) or in a co-operative electric-petrol mode at any speed.
Together, the 2.4-litre petrol engine and 40kW electric motor produce a combined power output of 154kW and 265Nm of torque and when it’s running on electric alone produces no emissions. Overall combined emissions are estimated to be 99 grams of CO2/Kilometre.
Kia says the system’s configuration does not have a requirement for a high-capacity electric motor and generator, saving weight and cost. Fuel economy is rated at 6.2L/100km in the combined cycle. This is aided by lowering the car 5mm and including an ‘active air flap’ in the front grille, smooth under-floor panels, low-drag wheels and low rolling resistance tyres.

Mazda’s next rotary powered machine is often the subject of rumour and speculation with claims that the RX-Series of vehicles may end with the RX-8. But fresh reports are suggesting that there will be an RX-9 and what’s more, it will use a hybrid drivetrain borrowed from Toyota.
These latest rumours have some weight behind them because last year an agreement was signed between Mazda and Toyota that would have the Zoom-Zoom company licensing the same hybrid tech that powers the Prius. Back then, Mazda announced that its first hybrid vehicle would reach the market in 2013. But nobody really thought it would come in the form of an RX-9.
Naturally a rotary engine will still spin under the vehicle’s bonnet, but it will likely take on a low-powered form with the hybrid system adding extra grunt. Doesn’t sound so flash right? Well not when you consider the rotary motor’s traditional design flaws of weak torque at low rpm, leaky seals and high fuel consumption. If the borrowed hybrid system can solve these issues it may be what saves the rotary engine from production car extinction. Continue reading “New Mazda RX-9 could use Toyota’s hybrid drivetrain” »

In 2014 Holden is on track to launch its next-generation VF Commodore and the new model comes carrying serious expectations and some new technology. Fans can expect significant savings in fuel economy, improved aerodynamics, new electric power steering and it will also be the first Aussie-built car to use mass produced aluminium panels in its construction. To remain competitive with vehicles like the Toyota Camry Hybrid, Holden’s Commodore will be saving weight wherever it can.
Total fuel savings will be in the region of 7% off the current figures of the VE Commodore range (pictured). This will drag the 9.1lt/100 km combined rating of the 3.0 L V6 SIDI down to a more acceptable 8.4 lt/100 km. The older 3.6 L Alloytec V6 will drop to 9.1 lt /100 km (26 mpg) down from its current 9.8 lt/100 km. The fuel saving measures are partly funded by the Australian federal government, which has used AU$39.8 million from the discontinued Green Car Innovation Fund.
The entire VF model’s development will apparently cost just AU$189 million which is a huge decrease on the rumoured one billion that was spent on the VE Commodore. Continue reading “New VF Holden Commodore to save weight with aluminium panels” »

Honda’s promising CR-X successor, the hybrid CR-Z could still be the excitement machine badge fans have been hoping for. Honda’s tuning arm Mugen is preparing to come to the rescue with a high performance version named the CR-Z Mugen and the first official photos of this hot hybrid hatch have been dropped.
Being prepared for a official debutl at the UK’s Goodwood Festival of Speed this July the hotter CR-Z looks suitably staunch but it’s the performance ability that Honda fans want to know about. While exact details haven’t been released, Honda has revealed that early tests with a prototype car based on a standard CR-Z and a mid-tuned engine has given a 0-100km/h sprint time matching that of the European market Civic Type R at 6.6 seconds. But that wasn’t enough, and Mugen has pushed on by increasing output a further 15 percent and reducing the chassis’ weight by 50 kilograms, overall performance is now expected to be more rapid than the Type R’s.
That seems a fair result form the CR-Z’s supercharged 1.5-litre i-VTEC four and electric assist motor. The CR-Z Mugen will also get tweaks like upgraded brakes and suspension, a carbon fibre bonnet and forged alloy wheels. For styling, there is a new body kit with a high rear wing and diffuser to improve dynamics. Continue reading “Honda drops images and details on its CR-Z Mugen” »

Jaguar has officially confirmed that its striking and environmentally friendly C-X75 supercar prototype will be taken into production.
The hybrid model first debuted as a concept at the Paris Motor Show last year and many thought that’s as far as it would go, but Jaguar have other ideas. The C-X75 is a hybrid supercar that produces less than 99g/km of CO2 emissions but for performance can rival the best supercars in the world and boasts a top speed of over 322 km/h (200mph).
The C-X75 will be an all-wheel drive machine with a “downsized, highly-boosted petrol engine coupled with two powerful electric motors,” says Jaguar, although the automaker is staying tight-lipped with any more details than that.
Jaguar will team up with the Williams F1 team to build the C-X75 and with Formula 1 preparing to switch to four-cylinder engines by 2013, it is possible that the C-X75’s powertrain will use similar or the same technology being developed for the Williams F1 team.
As a concept car the C-X75 used four 145-kW electric motors (one at each wheel) with two small turbine engines to create electrical current. But the production C-X75 will likely opt for a more conventional setup. Continue reading “Jaguar sending C-X75 hybrid supercar into production” »

Good news for fans of Honda’s long-dead NSX supercar with fresh reports that the model line is on the way back from oblivion.
At the recent Shanghai Auto Show the Japanese automaker revealed plans for the development of a new hardcore sports car that will become spiritual successor to the iconic NSX.
Honda Motor Company president, Takanobu Ito brought the big news and said the new car won’t feature the stonking V10 engine that had been planned for the next NSX, as the company scrapped this project back in 2008. But Ito did promise that the future NSX would be “exhilarating to drive and also environmentally friendly”. With those words in mind, it’s likely the car will use an electric motor to boost power for a conventional gasoline engine, much like the CR-Z sport hybrid. But unlike the limp CR-Z, the NSX successor will be positioned as a full-blood high-performance hybrid vehicle.
The initial plans for an NSX successor were cancelled by former Honda president Takeo Fukui, who told fans it was a cost-saving measure. Before the project was shelved the new car was expected to have a front-mounted V10 engine pumping out at least 500 ponies. It was this drivetrain, in concept form, that was later used by the Honda HSV-010 GT racecar. Continue reading “Honda restarts next-gen NSX development” »

Honda’s new Insight hybrid is a little like the Terminator – a character made famous by the sci-fi films of the same name. Like the staunch film figure the Insight is here on earth to terminate something – excessive fuel usage. And like the film’s character the Insight isn’t the first model but is stronger, and more advanced than its predecessor. But unlike the Terminator we’ve seen on screen, the Honda Insight isn’t going to be killed off after two hours. The Insight represents a genre of vehicle that is here to stay and while Toyota’s Prius may be winning the battle so far, it feels like the hybrid wars are just beginning. Honda’s Insight is a machine that’s important for the future so Car and SUV enlisted for a test drive today.
The first generation Insight, a two-door coupe is a rarity on NZ roads, but is easily spotted because it looks odder than a $3 note. For the sequel, Honda has opted for a more practical four-door hatchback body shape and few of its predecessors styling cues remain.
Up front, Honda’s corporate face is accented by blue-tinted headlight lenses and a grinning front bumper with recessed fog lamps. Along the flanks, flattened wheel arches are partially filled by 15-inch 7-spoke alloy wheels – standard on our tested S spec model. At the rear an almost flattened rear windscreen works into a tinted vertical glass panel in a look that’s reminiscent of the second generation CR-X. Despite the aggressive styling, the windows are large and visibility is very good all around, including its radical rear. There are clear similarities in wedge like shape between the Insight and Toyota’s Prius caused by both cars’ designers chasing down optimum aerodynamics.
