Volvo C30 Electric tested in rough winter conditions
The Volvo C30 Electric has been exposed to rough winter conditions in order to ensure that the battery-powered car runs smoothly in temperatures as low as -20° Celsius. Volvo Cars' requirements on the C30 Electric are just as stringent as on all other Volvo models and the battery-powered car is exposed to the same test regime. On top of this, several new test methods have been developed for the electric vehicles. All in all, over 200 different tests have been performed. "We must ensure that the C30 Electric performs as intended when driving, parking and charging in a variety of conditions, from normal to very cold or hot. Northern Sweden is the perfect place to do sub-zero temperature testing," says Lennart Stegland, director of Volvo Cars' Special Vehicles. The Volvo C30 Electric is equipped with three climate systems: * One supplies the passengers with heating or cooling. * One cools or warms the battery pack as necessary. * The electric motor and power electronics are water-cooled. Bio-ethanol powered heater The C30 Electric has a innovative solution that makes it possible to get comfortable heating in cold winter conditions without compromising the battery driving range. Climate control in the passenger compartment takes place via a bio-ethanol powered heater fitted in all cars. The car's ethanol tank can carry 14.5 litres of bio-ethanol. It is also possible to run the climate unit on electricity from the batteries. In electric mode an immersion heater warms up the coolant in the climate unit. "The driver can program and control the climate unit to suit the trip. Ethanol is the default mode that is used when the battery capacity is needed for driving extend mobility to its maximum. However, on shorter distances electricity can be used to power the climate system," explains Lennart Stegland.
2012 Mercedes-Benz CLS 63 AMG official promo
Mercedes-Benz has announced full details on the 2012 CLS 63 AMG model. New for the CLS 63 is now AMG's 5.5 liter biturbo V8 engine, which replaces the outgoing naturally aspirated 6.3 liter V8. The new 5.5 liter biturbo unit features a peak output of 410 kW (557 PS/550 bhp) and 800 Nm (590 lb-ft) of torque with the AMG Performance package. The standard engine configuration is rated at 386 kW (525 PS / 521 bhp) and 700 Nm (516 lb-ft) of torque. Both units are mated to the AMG Speedshift MCT 7-speed sport transmission. Fuel economy on the standard CLS 63 AMG now comes in at under 10 liter/100 km (a noteworthy achievement) - with a 9.9 liters per 100 km rating on the European cycle (NEDC). That represents a remarkable 32 percent improvement in fuel-economy over the predecessor's 6.3 liter unit with an output of 378 kW (514 PS/510 bhp) and 630 Nm (465 lb-ft) of torque. That new fuel-economy rating comes by means of a stop/start system, engine technology such as piezo injectors and an aluminum crankshaft, as well as the use of aluminum panels in the body. The 0 to 100 km/h sprint is 4.4 seconds for the standard model and 4.3 seconds for the CLS 63 with the AMG Performance package. The standard variant has a top speed electronically limited to 250 km/h (155 mph). The CLS 63 AMG comes with 3 drive modes: 'S' (Sport), 'S+' (Sport plus) and 'M' (Manual) and features AMG Ride Control suspension for a smoother, more exact ride quality with 3 modes of its own: Comfort, Sport and Sport Plus. The 2012 CLS 63 AMG comes standard with high-performance LED headlights, AMG light-alloy wheels in a new triple-spoke design with 255/35R19 and 285/30R19 tires front and rear, respectively. The AMG Performance package also offers a ceramic high-performance composite braking system, carbon fibre/black piano lacquer trims elements, door sills with illuminated AMG logo, carbon-fiber spoiler lip for the boot and red brake calipers, a seperate set of 19-inch light alloys in a double 5-spoke design and, aside from the aforementioned performance Boost, the package includes a top speed limit bumped up to 300 km/h (186 mph). Prices in Germany for the 2012 Mercedes-Benz CLS 63 AMG start at €115,846.50 including 19 percent VAT. The AMG Performance package rings in at €7735 (VAT included).

2011 BMW M5 F10 on Nurburgring
Although questions are raised as to whether or not the next M5 will have an engine that produces more than the 500 horsepower in the current M5's V10, it is expected to have an engine that generates 30% more torque than the V10. That would raise maximum torque from 380 ft-lb to nearly 500 ft-lb. This car's performance could match, or exceed, the 555 hp and 501 ft-lb of torque found in the 4.4-liter twin-turbo V8 used on the BMW X5 M.
