Hennessey Z700: Track-Ready 2010 Corvette ZR1 with 705HP, 775HP or 1000HP

Eager to satisfy those who believe that too much horsepower is never enough, Hennessey Performance Engineering has introduced an uber-Corvette in the form of the 2010 ZR1-based Z700. The American tuner claims that the track-orientated Z700 is to the Corvette what the GT3 RS is to the Porsche 911 and the ACR to the Viper. To be produced in a limited run of 24 units for the 2010MY, the Z700 features an array of performance enhancements including an upgraded version of the ZR1's LS9 V8 engine.

The upgraded supercharger, exhaust and air induction systems help lift output from 638 horsepower to 705 horsepower at 6,400 rpm and peak torque to 717 lb-ft at 3,200 rpm. The result is a zero to 60mph (96km/h) sprint time of just 2.9 seconds while the quarter mile is covered in 10.6 seconds at 134 mph. The standard 2010 Corvette ZR1's times are 3.4 seconds and 11.3 seconds at 131 mph respectively.

And if that ain't enough, Hennessey also offers two optional power kits that boost output to 775HP and a massive 1,000HP.

Additional mods on the Z700 include a set of lightweight carbon fiber wheels wrapped in Michelin Pilot Sport Cup tires, which Hennessey says reduce rotating weight by nearly 60 lbs, a lowered suspension and a new aero parts such as the carbon fiber front splitter, canards and rear spoiler that are said to add over 300 lbs of downforce.

Inside, the tuner has upgraded the ZR1's cabin with lightweight carbon fiber seats and Alcantara steering wheel and shift knob.

The price for the basic Z700 including the 2010 ZR1 donor car has been set at $207,150 US or at today's exchange rates, €149,312. That's almost double the price of the factory 2010 Corvette ZR1 638HP that starts from $104,920 and four-times the cost of the basic Corvette Coupe 430HP V8 that begins from $49,515.

James Robbins’ Corvette Design Study: Close But No Cigar

Here at Carscoop, we love us some Corvette design studies. Heck, if we wanted to we could probably serve up a new one every day of the week.

Today’s CAD mock up comes from transportation design student James Robbins. Think of it as a C6.5, a stopgap measure between the current gen Corvette and a future C7 model. The design brief required Mr. Robbins to use the basic proportions of the C6, which limited what could be done with the design.

Now here’s my two cents:

I find the shape of the bootlid and the V-shaped side intakes to be quite pleasing to the eye, but the ugly Dodge Viper / Ferrari 458 Italia taillights don’t fit the car at all. Also, the front end styling is a bit too conservative and I feel that more could have been done with the glasshouse. The overall design is good but it’s hard to say if that’s due to Mr. Robbins’ tweaking or the C6’s nice proportions.

I can’t help but feel that with a little more work around the head- and taillights, this could have been a real stunner. As it stands, it’s a good effort though just not quite there. But don’t take my word for it. Voice your own opinion in our comments section.

Chevy Releases Official Prices and New Photos of Corvette Grand Sport

Along with the announcement on the production of the 1,500,000th Corvette, General Motors today also confirmed pricing for its 2010MY Corvette Grand Sport models. The coupe version of the Grand Sport starts at $55,720 while its convertible counterpart from $59,530 with both prices including a $950 destination freight charge. The new Grand Sport combines the Corvette's LS3-based powertrain with wide-body styling, a wider track, beefier Z06-size wheels and brakes and a race-spec suspension.

With the standard exhaust system, the LS3 6.2-liter V8 engine is rated at 430 horsepower and 424 lb.-ft. of torque (575 Nm), however, customers can opt for a two-mode exhaust system that increases power ratings to 436HP and 428 lb.-ft. (580 Nm). The LS3 can be matted to either a six-speed manual or six-speed automatic transmission.

"The Corvette Grand Sport achieves a 0 - 60 time in less than four seconds, pulls 1.0g on the skid pad and still boasts an impressive 26 highway mpg," said Karen Rafferty, Chevrolet Product Marketing Director. "These numbers are unmatched by any of Corvette's competitors."

List of special features for the Grand Sport:

• Wider front and rear fenders – including specific front fenders with integrated Grand Sport badges
  
• Z06-style front splitter and tall rear spoiler
  
• Functional brake ducts and extra cooling
  
• Unique 18-inch front and 19-inch rear wheels; painted finish standard and chrome finish optional
  
• Large 275/35ZR18 tires in front and 325/30ZR19 tires in the rear
  
• Z06-size brakes, including 14-inch (355 mm) front rotors with six-piston calipers and 13.4-inch (340 mm) rear rotors with four-piston calipers
  
• Specific manual transmission gear ratios
  
• Specific rear axle ratio on automatic-equipped models

General Motors Builds 1.5 Millionth Corvette

While GM was preparing for bankruptcy, the Corvette reached yet another major milestone in its almost six-decade-long history with the production of the 1,500,000th car. The commemorative model left the production line at GM's Bowling Green Assembly plant on May 28, but the company decided to delay the announcement for a couple of weeks for apparent reasons. Similar to the first, 500,000th and 1 millionth Corvettes built in 1953, 1977 and 1992 respectively, the 1.5 millionth Corvette is a white convertible (3LT) with a red interior and a black top.

"The 1.5 millionth Corvette is a great example of how Chevy is America's Brand," said Karen Rafferty, Chevrolet Product Marketing Director. "For nearly 60 years we have built America's Sports Car and this milestone is a solid proof point."

1985 BMW 557i with Corvette V8 Heart Transplant

Owning a mint condition E28 BMW 5 Series would be a dream come true for most bimmer fans. However, the owner of this Euro-spec 1985 528i was probably not impressed by the stock 2.8-liter powerplant’s 184-ponies, so he performed an engine swap.

If it was up to me and money wasn't an object, I would've probably tried to fit a V12, but the 1999 Chevy LS1 V8 isn’t a bad fit either - that is, if you really feel the need to hear an American V8 burbling under the hood of a vintage German sedan.

The seller of the car claims that the new engine has clocked up only 6,600 miles since the open-hood surgery was performed and that he has invested more than $35,000 in the vehicle over the years.

According to the description, the spiced up Bimmer features a set of 750iL-sourced front and 540i rear brakes, custom headers and exhaust, modified suspension (with Bilstein shock absorbers and H&E springs) and wheels from a 540i.

There are interior appointments as well, such as power sport seats, XM radio and improved soundproofing. Judging by the photos, it’s looks like the car was taken care of. The body looks OK, the engine bay is neat and the seats have just the right amount of wear and tear, which gives the leather character.

Furthermore, the car’s papers seem to be in order, too, so it could make someone very happy in the future. For now the seller’s reserve was not met, as the bidding stopped at $11,400.
