There are many fans who have been waiting for quite sometime now for the grand launch of the Corvette C7. It has nothing to do with being hardcore Corvette fans, nor will the next Corvette be drastically enhanced in terms of technology or aesthetics. But the key thing is that with our growing awareness about our environment and its effects on our financial condition – all that we are curious to know is whether Chevrolet will get the hint and stop using the trade mark V8 engine. Tadge Juechter, the chief engineer at Chevrolet had revealed in a video a few months back of the Corvette being the company’s most favored product. This had led many to speculate that the next generation Chevrolet will continue its reliance on the V8 engine that made them famous, albeit with some modification that is necessary to keep pace with the times.
The 2013 Chevrolet Corvette – and not the 2011 edition as was earlier planned will have a 5.5 liter small block V8 engine under its hood in its front engine, rear wheel drive setup. The engine though will be more powerful in spite of its smaller volume, capable of churning out 440 hp. This is about 5 hp more than the 6.2 liter and 7.0 liter engines that the previous Corvettes dished out. The Corvette will now also have a better economy in terms of fuel performance while the engine will also feature a revised combustion system and aluminum block and heads.
We can say for certain that the engine will not be the only change about the new Corvette. For there are also rumors that the Chevrolet will at last raise the quality of the materials that is used in the sports car, which means an end to the almost incessant complains about poor quality of materials used for generations might finally comes to an end. The new Chevrolet sports car will see higher end seats that resemble bucket seats. If Chevrolet wishes to keep up with the times then they should definitely consider putting in high-tech features in the new Chevrolet. After all, if the Ford Focus is able to get technologically updated then we may expect better things from the Corvette as well.
Latest details about the new edition Corvette suggests that the car will have a European styled, small block, turbocharged V8 engine. The new engine will be a little bigger than the 3 liter displacement and will be of an overhead-cam design instead of the conventional overhead-valve design. A dry sump oil system that is friendly to the high performance road courses and not straight line acceleration capabilities will be used. We can expect to see an output of 125 Hp per liter and an overall of 400 HP. Seems like the Porsche 911 and the Lamborghini Gallardo have got a competitor.

Thomas Merker, chief engineer for the M-Class, put it this way: “We want nothing less than the best SUV in the market”. And that is the clear Mercedes intent for this truck.
Getting underway from a stop on the CBR is easy due to a rather low first gear, responsive cable-actuated clutch and one-finger-easy lever pull. Final drive gearing is 16/42, more reasonable for street use than some of the other bikes’ final drive because it helps maximize engine power.Speaking of power, or a lack there of, the Honda didn’t really astound us with its mid-pack outright horsepower output. You can argue that 153.08 hp @ 10,800 rpm isn’t anything to scoff at, but it does leave the CBR1000RR three horsepower down on the GSX-R1000 and about a half pony up on the RC8R. That’s not real impressive on paper. What saves the CBR is its fat, and class-leading, mid-range engine performance that outshines the rest of the Inline-Fours. The dyno graph shows how the CBR stays above the rest of the Fours from five to ten-grand. This, combined with the shorter gearing, makes it a real torque-monster on the street. Its maximum torque rings in at 77.79 lb-ft at 9700 revs, which is just a single lb-ft shy of the S1000RR – roughly 10 down to the Twins. This helps the Honda accelerate harder than some of the other bikes during the majority of riding scenarios.With its strong mid-range engine performance always on tap, the Honda offers the best fuel economy figure observing an average of 36.7 mpg. The CBR also benefited from having the second-largest fuel capacity at 4.7 gallons which gives it a range of 158.9 miles between fill-ups.
While the Honda’s powerband impressed us, its overall character, including sound, was lacking. When the engine is loaded it doesn’t really deliver the same sensation of speed as the other superbikes. The roar of the engine seems muted which doesn’t make it quite as exciting. The results from the sound test show that the CBR equaled the BMW’s decibel rating of 82 dB at both idle and 100 dB at half maximum engine speed, which really came as a surprise considering how quiet it seems on the road. We also noticed that the engine vibrated more than some of the other Inlines, including the silky-smooth ZX-10R and Yamaha R1.
“Of all the bikes in this test the Honda is probably the easiest for me to ride in the twisties,” comments Gauger. “You don’t need to put a lot of input into the bike to make it change directions it just kind of does it by itself… at least it feels that way. In my opinion there isn’t a better handling bike out there.”
