Blue Devil / ZR1

Motor Trend Corvette ZR1, Nissan GT-R, Ferrari 599 GTB and Porsche GT2

Finally, someone had the balls an epiphany to line up four supercars and take them head to head down the strip. Motor Trend pitted the Corvette ZR1, Nissan GT-R, Ferarri 599 GTB and the Porsche GT2 in this race for bragging rights. America’s best against Germany, Japan and Italy. It’s one thing to compare performance specs on paper and quite another to actually see 4 cars with a combined 2,260 horsepower thunder down the strip.

The 480 horsepower all wheel drive Nissan GT-R gets the jump on the three other cars and takes the lead. The rear engine 530 horsepower Porsche GT2 then sprints to the lead of the pack with the 612 horsepower V12 Ferrari 599 GTB hot on its heels. But then the superior torque of the ZR1 digs in and within seconds the king of the hill takes the lead and finishes by over a car length.

This was a great video to watch and we hope the magazines do more of these head to head comparisons.

Warp Speed in a Box: Corvette ZR1 638-hp LS9 Crate Engine

by Keith Cornett on October 29, 2008

The 638-hp LS9 6.2L V8

Listen up resto-mod and performance car builders! Beginning next fall you’ll be able to buy the 638 horsepower supercharged LS9, the new engine built by GM to power the 2009 Corvette ZR1. The engine comes fully dressed and needs only an external oil and coolant tanks, an ECU and wiring harness. The engine features roughly the same dimensions as the 6.2L LS3 so its installation possibilities are plenty.

The LS9 features a mind-blowing 638 horsepower and 604 lb.-ft of torque, more than enough power for winning bragging rights at the track or car show. The heart of the Corvette ZR1 is expected to be made available during the third quarter of 2009. There is no pricing available yet for the LS9, but a quick search of crate engines shows that the Z06′s LS7 is being sold for around $14,000 so expect to pay a bit more.

Here is the press release from GM Performance Parts:

GM PERFORMANCE PARTS SET TO UNLEASH THE SUPERCHARGED LS9 CRATE ENGINE

LAS VEGAS – The LS9 6.2L supercharged V-8 is the power behind the most powerful and fastest production car in GM’s history – the 2009 Corvette ZR1. In the third quarter of 2009, it will be available as a complete crate engine package from GM Performance Parts. It delivers a stunning 638 horsepower (476 kW) and 604 lb.-ft. of torque (819 Nm).

The LS9 crate engine will be the ideal all-in package for enthusiasts and racers who want the ultimate LS power plant for their project cars, from resto-modified vintage Corvettes, muscle cars and street rods to late model F-bodies and “shoebox” Chevys. The supercharger and charge cooler are integrated in the engine’s valley for a lower profile, allowing creative builders to fit the engine in a variety of applications with plenty of hood clearance.

The engine’s 6.2L displacement is shared with the LS3, but the LS9 is built for high-revving power with a supercharger. It uses stronger cylinder head castings and steel cylinder liners that are honed with a deck plate installed to maximize performance and cylinder sealing.

High-rpm-validated lightweight reciprocating parts, including titanium intake valves, are used, along with high-flow cylinder heads that draw the charge forced on them by a sixth-generation supercharger. A new, four-lobe rotor design delivers greater power at the low end and sustains it longer through the rpm band for broad, on-demand power, whether off-idle or at speed. A dual-brick charge cooler is integrated on a unique manifold system that mounts the “blower” in the engine’s valley, with charge cooler on top.

GMPP’s LS9 crate engine assembly comes fully dressed, including the ignition system, supercharger assembly, exhaust manifolds and more. It also includes the production dry-sump oil pan and provisions for the charge cooler’s liquid cooling system. Builders will need an external oil tank, external coolant tank (for the charge cooler) and an ECU/wire harness.

Motor Trend tests the 2009 Corvette ZR1

Late last week we brought you the results of Motor Trend’s Corvette ZR1 instrumented test results. In their testing, MT claimed they hit a wind corrected 200.4 mph on the five mile high speed loop at Chrysler’s Arizona Proving Grounds. Video surfaced today showing a three camera view of test driver Didier Theys hitting that mark. Although he backs it down when the speedometer hits over 200 mph, it looks as though the ZR1 still had some legs for more.

Just to recap those performance test numbers from Motor Trends, the Corvette ZR1′s 0-60 mph was a blistering 3.3 seconds and it flew through the quarter mile in 11.2 seconds at 130.5 mph. The Corvette ZR1 also pulled 1.10 g on the skid pad and stopped 60-to-0 in just 97 feet.

2009 Corvette ZR1 on the Nurburgring

Back in June when GM Development Engineer Jim Mero drove the 2009 Corvette ZR1 around the Nurburgring in 7:26.4, we wondered out loud what that time could have been if one of Corvette Racing’s drivers, particularly Jan Magnussen, had the opportunity to drive the 6.2L Supercharged Corvette around the world’s all-important 12.9 mile track. According to several sources, we’ve learned that on Monday, October 27th, Jan Magnussen drove the Corvette ZR1 to a time of 7:22.4, besting the previous time by 4 seconds!

Jan Magnussen’s extensive knowledge of the Nordschleife and his employment with Corvette Racing makes him the perfect candidate for a second Corvette ZR1 attack on the ‘Ring. It was Magnussen that left Corvette’s first mark on the Nurburgring with his Corvette Z06 lap time of 7:42.9 back in 2005.

There is somewhat of a conspiracy afloat about this time, as it was originally posted to FasterLaps.com here and then the entry was deleted. It’s posted again here with credit from Autoblog which listed the information from the original post:

Lap time ID: 49063045e0652
Car: 2008 Chevrolet Corvette ZR1 (476 kw)
Track: Nordschleife
Lap time: 7.22.4
Driven by: Jan Magnussen
Submitter IP: 24.208.168.135
Date & time of submission: 27/10/08, 23:19:01

Without proof including video or a substantiated third-party eyewitness, this time will remain suspect. We also can’t imagine that GM wouldn’t take the opportunity to roll-tape as Nurburgring times have become such an important selling tool for the new super cars, Corvette ZR1 included.

Lastly, this story really leaves us wanting more. How about a race-prepped ZR1 complete with racing tires, roll bar and that really fast looking velocity yellow paint? Now that would be something to see!

Motor Trend tests the 2009 Corvette ZR1

Motor Trend hauled a Corvette ZR1 down to Arizona where they strapped their performance measuring instruments to the 638 hp King of the Hill and went wild on Chrysler’s Proving Grounds. No, the merger ain’t done yet, but Chrysler’s five mile high-speed loop is one of the few places in the US that has the space to test the Corvette ZR1′s top speed.

In addition to bringing their instruments, Motor Trend also brought a test driver who knows how to drive, former IndyCar driver and Daytona 24 Hours winner Didier Theys who drove the Corvette ZR1 and recorded the best performance numbers we’ve seen yet. The magazine hit the magic 200 mph mark, corrected due to a 25-mph headwind, and was still pulling according to the VMAX.

In the other measurements that matter, the Corvette ZR1 performed superbly. 0-to-60 mph was achieved in 3.3 seconds and the ZR1 blew through the quarter mile in 11.2 seconds at 130.5 mph. The huge Brembo carbon ceramic brakes stopped the Corvette ZR1 from 60 mph in just 97 feet. Finally, the lateral acceleration averaged at 1.1 g.

Motor Trend enjoyed their time spent with the new Corvette, and frankly, who wouldn’t. Check out the article’s opening statement:

Prepare to be humiliated. If, that is, you’re a sports-car maker other than Chevrolet. Call it what you will — “Blue Devil,” “King of the Hill,” even “Steve” – the all-new 2009 Corvette ZR1 is a world-beater.


Here is a comparison of the three instrumented Corvette ZR1 tests:

MAGAZINE 0-60 MPH 1/4 MILE SKIDPAD BREAKING
Motor Trend 3.3 Secs 11.2@130.5 1.10 g 97 ft
Popular Mechanics 3.7 Secs 11.5@127.8 1.04 g 94.9 ft
Car & Driver 3.4 Secs 11.5@128.0 1.07 g 142 ft*

* Car and Driver’s breaking distance test is 70 mph to 0, the other magazines are rated at 60 mph to 0.

2009 Corvette ZR1 at Milford

Last week we brought you the first instrumented test results on a 2009 Corvette ZR1 performed by Car and Driver. This week, Popular Mechanics strapped their Racelogic VBOX GPS-based data recorder to the new supercharged 6.2L Corvette and went at it on one of the test tracks inside GM’s Milford Proving Grounds. PM’s enthusiasm for the car can be summed up in one word: WOW.

One of the more interesting parts of this test is how Popular Mechanics goes into much detail about the ZR1′s launch control works, something we haven’t heard a lot about. Here’s their description of what it is and how it works:

The system automatically limits engine torque to keep the rear tires hooked up. It’s different from traction control because launch control actually allows some wheel spin and progressively feeds in power to produce jack-rabbit starts. With it, even novice drivers can maximize nearly all the thrust the ZR1 has to offer.

With the launch control engaged, the ZR1 hits 60 mph in 4 seconds and does the quarter mile in 12 seconds at 127 mph. Turning off the computer aids and relying on technique and driver skill, the Corvette ZR1 nailed 60 mph in 3.70 seconds, 100 mph in 7.80 seconds, 150 mph in 16.61 seconds. The quarter mile was run in 11.50 seconds at 127.82 mph.

Last week’s Car & Driver instrumented test also had the ZR1 running the quarter in 11.50 seconds at 128 mph.

As a further comparison, Popular Mechanics last test of the Z06 showed the 505-HP Corvette hitting 60 mph in 4.37 seconds and the quarter mile in 12 seconds at 120.90.

Finally, Popular Mechanics called the braking and skidpad results impressive with the ZR1 pulling a 1.04 g on the skidpad and braked 60-to-0 mph in 94.98 feet.

Here are the full results Popular Mechanics’ Corvette ZR1 Instrumented Test:

Car and Driver’s Corvette ZR1 Instrumented Test Results

by Keith Cornett on October 9, 2008

2009 Corvette ZR1

While many of the major car magazines have test driven the new 6.2L supercharged Corvette ZR1 and dubbed it the “Best Vette Ever”, Car and Driver took their test drive a step further by strapping their measuring equipment into the newest Corvette and recorded the first performance data by a neutral party. The verdict? How about one of the best super cars ever!

How’s this grab you for performance:

  • Zero to 60 mph in 3.4 seconds
  • Zero to 100 mph in 7.6 seconds
  • 11.5 seconds, 128-mph quarter mile

Oh, but there is so much more. On the skidpad, the Corvette ZR1 pulled 1.07 g’s and those massive 15.5 inch ceramic rotors stopped the Blue Devil from 70 mph in just 142 feet – the shortest stopping distance Car and Driver ever recorded for a production car. The editors claim they tried to reach the Corvette ZR1s maximum velocity of 205 mph but ran out of room.

Calling the Corvette ZR1 the “giddy bargain among ultra high-performance automobiles”, the Car and Driver team says just one “stab of the accelerator pedal should serve as a reminder that not only is the ZR1 the best Corvette ever, but it is among the best sports cars available today.”

Check out the full review where some of the worlds best super cars including the Aston Martin DBS, Lamborghini Murcielago LP640, Mercedes-Benz SL65 AMG, Dodge Viper and the Ferrari 599GTB Fiorano are compared to the new King of the Hill, the 2009 Corvette ZR1.

Is the Sun Setting on the Corvette ZR1?

A proverbial bombshell was dropped last night when Patrick Gramm of DigitalCorvettes.com posted news about GM halting Corvette ZR1 production. Patrick was told by a source that ZR1 production was to be halted and the model may have been cancelled despite no known issues that would warrant a production stop.

The story was given credence with Corvette Conti’s post about Corvette ZR1 orders with production dates suddenly disappearing from the system. Corvette orders are assigned a Target Production Week (TPW) and when those TPWs start disappearing, people get nervous.

We confirmed the order process with Kerbeck Corvette’s Sales Manager Dave Salvatore who told us that not seeing a TPW is completely normal, especially on early production cars. Dave says they did the same thing to the Corvette Z06s when they came out. “They do this so as not to get people mad or nervous if there’s a delay during the early production.”

Fact is, production has been halted on the Corvette ZR1 as well as the other three models this week as GM idled the Bowling Green Assembly plant to allow for a bit of constriction in supply. Salvatore says that he is hearing that once the plant’s operations resumes next week, Corvette ZR1 production will be doubled to make up for the loss numbers during the shutdown.

Finally, Autoblog weighed in, pulled out the rolodex and called GM’s Terry Rhadigan, Global Communications Director for Chevrolet, who responded with a terse statement designed to put this rumor to bed: “Not True”.

Going back to the Digital Corvettes post, there are several members with “sources” within the Corvette program that have provided reliable information over the last few years when it comes to Corvettes in general and the ZR1 specifically. They are saying that this rumor is not true and not what they are hearing. One of the members said the following:

The huge amounts of money that were spent on the ZR1 were for R&D. In other words, most of the money was spent before the car even went into production. That money is spent and gone…it’s never coming back. Killing the ZR1 at this point won’t get that money back and wouldn’t really save that much money in the grand scheme of things. There might even be penalties to pay to suppliers for cancelling the parts contracts. Even if you do cancel the contracts, how much are you really saving by not paying for the parts for a 2000-3000 unit/year vehicle program? Again, not that much in the grand scheme. It makes more sense to keep building this super-limited run vehicle and get all the money out of it you can. They will sell every one they build.

We count Patrick of DC as one of our online friends and his information is usually reliable. But I feel for the guy who may have led him astray on this if that’s the case. Patrick followed up with a comment in the thread that mentioned “balls” and “chopping block” so we’ll see where this story goes.

Top Gear Testing the Corvette ZR1

I warned you when we heard that Top Gear’s Jeremy Clarkson was testing driving the Corvette ZR1 out on the Bonneville Salt Flats about his tendency to talk glowingly about Corvettes and then bashing them. It’s beginning to look like that’s what we’re in for after we saw this quote about Clarkson’s time in the Corvette ZR1 in his very unflattering review of the Chrysler Sebring Cabriolet.

In the Sebring review, which Clarkson calls the “worst car in the World”, he’s ranting about the poor quality of American cars when he drops this in eight paragraphs from the end:

“I spent most of my time in America this time in a new Corvette ZR1. It is a fabulous car. Mesmerisingly fast, good looking and amazing value. But after three days the damn thing was beginning to disintegrate. It made me growl with annoyance and despair.”

The next seven paragraphs is typical Clarkson, bashing America and our lack of “history” as the root cause. I’m not going to go into any more details. His constant rants on the subject of American cars and therefore America itself is so tiresome. Unfortunately, he’s about to turn his sights on our favorite sports car and I for one could really care less…

[VIDEO] Another Corvette ZR1 on the Dyno pulls 549.9 RWHP!

by Keith Cornett on September 30, 2008

2009 Corvette ZR1 Dyno Sheet

The Vette Doctors of Amityville, NY had a customer bring his new 2009 Corvette ZR1 into their shop and this time we got three dyno runs on video. The sound this Corvette makes is impressive. I think that it would have been pretty cool to have been there in person to hear it.

The shop performed three base dyno pulls and their best run was 549.9 rear wheel horsepower and 500 ft-lbs of torque, better than what we saw last week when two Corvette ZR1′s averaged 535 RWHP on a dynojet. According to the post, these are adjusted numbers. That’s a 13.8 percent loss which again is within the normal parameters.

Now for the crazy part. The Corvette ZR1 is in the shop because the owner is “already looking for a little more power!”. Vette Doctors is working on some custom programming to get the full potential out of the new King of the Hill. They are also will be working with American Racing Headers to develop a ZR1 specific header system. The shop is hoping to have these changes on the car and back on the dyno in the next week and will be posting those new numbers as soon as they are available.
