Hyundai i40 Gets “Intelligent” Grille
Hyundai Motor Co.’s i-flow, a large sedan concept showcased at the Geneva auto show, is a test bed for a variety of technologies that will gradually find their way into the upcoming D-segment i40 sedan, Autocar reports.
The i-flow concept features an “intelligent” grille that dynamically controls engine cooling. The car also is fitted with solar panels on the roof and a thermoelectric generator that uses heat produced by the catalytic converter to power accessories.
The i-flow is powered by Hyundai’s first diesel-hybrid powertrain, a turbocharged 1.7-liter engine mated to an electric motor, lithium-ion-polymer battery and six-speed transmission. The powerplant is insulated to help cut the higher fuel consumption typical when starting a cold engine. Hyundai says the feature can maintain an engine temperature of 40°C overnight.
A conventionally powered version of the i40 debuts in Europe this year. A hybrid-powered version is due in 2011.
AMG Unveils Turbo V-8 Engine
AMG has developed a new 5.5-liter V-8 engine for the Mercedes-Benz S63 sports sedan that is more powerful than its 6.3-liter predecessor but also is 25% more fuel efficient. The engine, code named M157, will debut this summer.
If equipped with AMG’s performance package, the direct-injection twin-turbocharged engine generates as much as 571 hp and 663 lb-ft of torque. Yet fuel consumption is only 10.5 liters/100 km compared to 14 liters/100 km for its predecessor.
Low-Emission Cars Claimed 25% of European Sales Last Year
Western European sales of cars that emit fewer than 120 g/km of carbon dioxide jumped to 3.2 million units, or 25% of total car sales, last year, according to the industry association ACEA. The proportion compares to 16% in 2008, 11% in 2007 and 9% in 2006.
ACEA attributes last year’s surge to government scrappage plans that boosted demand for more fuel-efficient cars. The association says A- and B-segment cars accounted for 45% of total market sales in 2009, up 10 percentage points from the previous year.
The average vehicle sold in western Europe had a 1.6-liter engine, the smallest average displacement in western Europe since 1991.
Lawsuit Asks EC to Release Climate Data on Biofuels
Several European environmental groups have filed a lawsuit demanding that the European Commission release data about the negative impact of biofuels on climate change.
The groups have been trying since October to gain access to information they say may show that converting forests to cropland needed to grow biofuel materials will produce significant emissions of greenhouse gases. The EU has ruled that member states must use renewable sources—mostly biofuel—to supply at least 10% of their transportation fuel requirements by 2020.
The environmental groups say they want to determine whether using biofuels will actually reduce greenhouse gas emissions as intended.
