    2011 PORSCHE 911 GT3 R HYBRID 2.0

    Porsche 911 GT3 R Hybrid will mark its return to this year’s edition of the Nürburgring 24 hour race on June 25. The car is more powerful yet lighter and more fuel efficient than its predecessor, it is which carries the geeky ‘Version 2.0’ moniker. The 2011 edition of the Porsche 911 GT3 R Hybrid carries the geeky ‘Version 2.0’ moniker

    The racer’s hybrid powertrain comprises of a 470HP 4.0-liter six-cylinder boxer engine at the rear and two electric motors driving the front wheels. In the Version 2.0, the output of both electric motors has increased from 60kW (80HP) to 75 kilowatts (100HP) each, meaning that seconds at a time, pilots will now have an additional 200HP at their disposal.

    Porsche claimed that extra power is automatically activated through use of the throttle pedal and can be very useful when overtaking. Porsche has also optimized the hybrid system with the electric flywheel accumulator that stores energy now housed with the other hybrid components in a carbon fibre safety cell on the passenger’s side.

    In addition, thanks to the optimisation of the hybrid system’s high voltage components, the large louvres in front of the rear fenders were no longer necessary. The Germany company claims that these changes help reduce drag and lowers fuel consumption.

    Other changes for the 2011 model include the thoroughly updated cockpit as most of the displays and controls have moved to the steering wheel. According to Porsche, drivers can operate the rest of the functions via backlit buttons now situated on the centre console.

    2012 MERCEDES BENZ C63 AMG COUPE

    AMG division has been floated on a high-performance version of its recently launched C-Class Coupe. Stuttgart’s answer to the 450HP Audi RS5 and the 420HP BMW M3 coupes is built around the revised 2012 C63 AMG saloon and sticks with Mercedes-Benz’s familiar 6.2-liter naturally aspirated V8 lump.

    V8 powerplant in the 2012 C63 AMG Coupe will be offered in two states of tune. The basic version churns out 457HP and peak torque of 600Nm in EU-spec, and 451HP and 443 lb-ft in US-trim, for a 0 to 100 km/h sprint in 4.5 seconds [0-60mph in 4.4 sec] and an electronically limited top speed of 250 km/h [155mph].

    The AMG SPEEDSHIFT MCT 7-speed automatic that offers several modes including the Controlled Efficiency “C”, “S”, “S+” and “M” modes. These are selected through the new rotary control borrowed from the SLS AMG Gullwing model. Mercedes says gear changes in the “S+” and “M” modes take just 100 milliseconds. In addition, there’s a RACE START function that is said to allow “the driver to explore the vehicle’s full acceleration capability”.

    2012 Mercedes-Benz C63 AMG Coupe gets a modified chassis with a separate three-link front suspension, a reinforced multi-link independent rear suspension and a wider track at both ends, plus more negative camber all round and anti-roll bars with a larger cross-section. The high-performance braking system with composite front discs and the three-stage ESP (On, Sport and Off) complete the performance upgrades.
