Auto 2010: 2010 Lexus IS250 and IS350 Convertible
March 17th, 2010
Lexus had models like Audi A5 Cabrio, BMW 3-Series Convertible, and Volvo C70, when it unveiled the IS C in 2008 at the Paris Motor Show. And it seems they desire was a success, as the model easily combines the award-winning design of the IS sports saloon with outstanding open-top engineering ingenuity.
In two different version, the IS Convertible is offered: IS250 and IS350. The IS250C is powered by the same engine as the sedan version: the 2.5-liter V6 delivering 205 hp. The engine is mated to a six-speed automatic transmission. The IS350 is powered by a 3,6 liter V6 engine that delivers a total of 306 hp.
The IS 250C uses the front double wishbone and multink rear suspension format from the IS sedan range to give, which means it should have the same spirited drive as the sedan. According to Lexus, there are significant chassis revisions to handle the structural differences that come with the loss of the roof.
The 2010 IS250C has a MSRP of $39,440 when equipped with a six-speed manual transmission; the IS250C with a six-speed automatic transmission will be $40,610. The IS350C will have a MSRP of $44,890.
Auto News: Getrag’s new Boosted Range Extender Hybrid
March 16th, 2010
With every motorshow, the world threatens to move towards the electric vehicle that passes by with the various concept cars that are being released. With range extender electric vehicles like the Chevrolet Volt and the Proton EMAS proving to be a plausible solution for reduced emission and fossil fuel reliance motoring in the mid-term future, transmission manufacturers are getting worried – with electric motors taking over the duty of driving the wheels and the combustion engine re-designated for generator duty, there will be no need for transmissions.
At the METAV 2010 manufacturing and automation showcase, the Getrag presented a Boosted Range Extender, which is basically a two-cylinder internal combustion engine combined with an electric motor, an alternator and a Powershift 2-speed transmission. Getrag’s configuration calls of the components to be mechanically integrated together in one package, thus losing the packaging flexibility of range extender solutions that separate the electric motor from the combustion engine such as in the Proton EMAS.
The combustion engine can also be coupled to provide power whenever needed in parallel hybrid operation. But the combustion engine will also run in series hybrid mode, charging the vehicle’s batteries for the electric motor usage using the alternator mentioned earlier. In fact, this is a series-parallel hybrid like the Toyota Prius but seems to use a Getrag 2-speed gearbox and only 1 electric motor instead of 2 electric motors like in the Prius.
A compact Ford Fiesta hatchback is a teaser of what car the new range extender engine, which might just be skilled into as a demo unit.
It’s based on a 30/50kW electric motor, a 10kW generator, a 5kWh usable capacity battery and a 30kW internal combustion engine. The range achieved was 600km total when the combustion engine helped, but electric drive range on the NEDC cycle was 50km, while electric drive range at 50km/h constant was 70km.
