With 197bhp, 300Nm of torque and a top speed of 234km/h, a high performance version of the new 1.6-litre SIDI turbo engine will globally premiere in a Vauxhall Cascada at the upcoming Frankfurt Motor Show. The engine is one of the newly-designed Vauxhall four-cylinder SIDI (Spark Ignition Direct Injection) units and will join the existing 167bhp 1.6-litre SIDI turbo, available from its launch. The new power unit delivers 11 percent more power, including 300Nm maximum torque with overboost - 70Nm more than the comparable 1.6-litre turbo predecessor. At the heart of the SIDI turbo is a new engine block that can withstand a maximum combustion pressure of up to 130 bar in the cylinder. The block is made of grey cast iron with an aluminium baseplate. A different type of piston was also developed on top of a reduced compression ratio. Vauxhall engineers also achieved a high power output with exceptional refinement by optimising the car

Is Mazda committing to new rotary engine with SkyActiv technology?
FaezClutchless posted a blog entry in MyAutoBlog
Over the past one year, Mazda has hinted that their rotary engine usage has come to an end. The company had to struggle with stringent emission laws and fuel economy in its RX8 model and it looks like the RX8 would be the last Mazda model to feature the rotary engine. But a recent Twitter update by a Mazda PR employee shows otherwise. A recent twitter update revealed that Mazda is working on a new rotary engine for a new model and they will also feature their SkyActiv technology into it. The actual tweet also thanked supporters for their continuing support of the rotary engine and the RX8. No expected timeline was mentioned as to when we will see this. From what I could remember, SkyActiv focuses on three key areas: (1) Advanced engines with world-beating compression ratios (2) Highly efficient transmissions (3) Sophisticated lightweight chassis technology for high levels of crash safety performance and driving pleasure. If Mazda is going to increase compression ratios on its rotary engine, I wonder how that will help fuel economy, especially on its RX model. For Mazda fans, don -
The hardcore Mercedes-Benz E63 AMG isn't the only E-Class model that gets a new heart for the 2012 model year. According to sources in Mercedes-Benz, both the E350 and E550 models will receive new powerplants currently found elsewhere in the automaker's lineup. The E350 will now be powered by the automaker's new 3.5-liter V6 with direct-injection, an engine that is found under the hood of the C350 sedan and SLK350 roadster. Rated at 302 horsepower and 273 pound-feet of torque, the new engine provides power increases of 14 hp and 15 lb-ft over the current V6 while the use of direct-injection and a seven-speed automatic transmission will return improved fuel economy. The eight-cylinder E550 will ditch its naturally aspirated 5.5-liter V8 in favor of a twin-turbocharged 4.6-liter unit with direct-injection, currently found in the CL550 coupe. In the E-Class, this engine will be good for 402 hp and 443 lb-ft of torque, an improvement of 20 hp and 52 lb-ft respectively.

[extract] Ferrari could be working on its own super-performance version of Fiat's Multiair valvetrain technology, which effectively allows the cam profile to be altered dynamically through hydraulic actuators. Leaked documents indicate that Ferrari is developing a high-performance V8 engine with the Multiair valvetrain arrangement. Ferrari laid out the system in two-dimensional illustrations, which may indicate Formula 1-like air control over the valves in addition to the Fiat
