Jalopnik's Acquired Spy Photos of the 2014 Corvette C7

Back in early December we showed you the mock-ups done by the guys at Jalopnik of what they claimed was the C7 Corvette prototype, and it looks like they were pretty close. The lines along the roof and a-pillar, as well as the flairs around the rear wheels all seem dead on. The front lines--particularly those on and around the hood--look a little different, and thankfully they 2014 Corvette looks to be retaining the classic round tail-lights, unlike the Camaro inspired taillights on their mock-up. All in all, from what I can tell in these photos, the car looks to be a gorgeous one. The long and sleek lines are reminiscent of the European super cars without sacrificing the classic Corvette styling. Of course, we're still two years out so this model may see changes, and the camo disguise blanketing the car definitely make telling exactly how the finished product will look a difficult tak. Either way, Corvette spy photos are the holy grail of automotive spy shots, and these are some great ones:

GM Produces 100-Millionth Small Block

GM Produces 100-Millionth Small Block Engine

A ZR1 LS9 Engine just produced by Chevrolet was the 100-Millionth manufactured by the company.

In the past 56 years, since Chevrolet began producing small block engines, the bowtie emblazoned automotive company and the small block engine has been synonymous with one another. In that time, every iconic car produced by Chevrolet has been known and linked to their famous small-block engine design in some manner. Most recently, the fifth generation Camaro has become a small block powered icon on both road and track, much like it's LS small block powered big brother, the Corvette.

The sheer number there--100,000,000 for those who like lots of zeroes--really highlights the durability, reputation, and potential of the small block and speaks to the iconic nature of the GM engine. It is fitting then to also consider that the first small block, introduced in 1955, was built for the first generation Corvette and the 100-millionth produced was a hand-crafted work of art LS9 made specifically for the sixth generation Corvette's special edition ZR1--the fastest Corvette ever produced.

Chevrolet 1955 Small Block V-8 Engine

Of course, the transition from the first small block to the modern pinnacle LS9 is a long one, filled with numerous exciting and memorable engines. In 1992 Chevrolet first introduced its second-generation Small Block, known as the LT1, in to its Corvette. This engine became an absolute staple on tracks across the globe, and adorned various vehicles from that Corvette, to the F-Body Camaro and Firebird, and the B-Body Impala SS and Caprice Police car. The LT1, which featured a newly developed reverse cooling, is still being used in races all across the globe today.

Chevy LT1

Following the second generation, Chevrolet then introduced their first LS Engine in 1997. This third generation small block, which was first placed in the C5 Corvette, was an even greater step forward. The LS engines are all-aluminum small blocks, and the first of them, the LS1, was rated a naturally aspirated 350HP and 365 lb ft of torque--numbers that, today, are still incredibly impressive for a naturally aspirated 5.7L engine. The LS engine was then featured, in some form, in numerous different vehicles and even had a more powerful, LS6 version introduced in the C5 Z06 Corvette in 2001. This LS6 featured the same 5.7L displacement as its LS1 brethren, but put out a stomach churning 405HP and 400 lb ft of torque.

Corvette LS6 Small Block V8 Engine

Those numbers were fairly mind-shattering for a naturally aspirated engine of the LS6's size and weight, at least, until 2005 when the first of the fourth generation small block was released. In 2005 the Corvette went from its fifth generation vehicle to the now current sixth generation, and with the change in body also came the biggest change: the introduction of the Chevrolet LS2. The LS2 was almost identical to the LS6 engine in performance and displacement, but also featured a much more even Torque curve through-out the RPM range, and had the potential to be modified for incredible gains. It was from this base LS2 that the LS7--the now revered 505HP and 470 lb ft torque monster--was produced and introduced to the 2006 Corvette. Just one year after the update of the small block, this engine seemed to be where everything was building, and the Z06 became the undeniable greatest performance bang for the buck on the globe. Within the year, there were Z06's running against quarter-million dollar European exotics on racetracks all across the globe, and each one came with the distinctive sound and tone that only a Chevrolet small block V8 can deliver through the exhaust.

Of course, Chevrolet wasn't finished there (thankfully, they're dedicated to the production of envelope-pushing performance machines) and we saw such engines as the 430HP LS3 (now outfitting the base-level C6 Corvette and the Chevrolet Camaro SS), the LSA (a 556HP Supercharged monster that can be found in the world's fastest production sedan, the Cadillac CTS-V and will also hit the streets in the body of the new super-Camaro ZL1 this year), and the engine that would be made as number 100,000,000--the LS9.

Corvette ZR1 LS9 Small Block V8

The LS9 is an absolute marvel worth talking about as well, especially considering that everything before it brought us to this point. The LS9, which can only be found in the top of the line Corvette ZR1, produces an amazing supercharged 6.2L engine based on the LS3 block and putting out a ferocious 638bhp and 604 lb ft of torque. Those numbers, in combination with the Corvette's lightweight body and wide, aggressive stance, have produced a vehicle that runs track times that best it's $250,000+ competitors. Today, the ZR1 is the undeniable greatest bargain on wheels that exists for the performance minded consumer, and, as such, is the only engine fitting to be given the designation as number 100,000,000 of its kind.

Of course, Chevrolet's not stopping at 100,000,000 and the future of the small block engine holds a great deal of excitement. Already, official reports have come out that Chevrolet is updating their engine for the seventh-generation of their Corvette, and we may see the introduction of such features as direct injection and an upgraded combustion chamber design, as well as the improved performance and efficiency numbers to match. GM enthusiasts should expect to see the next small block engine first hit the streets in the C7 Corvette, scheduled for release some time in 2014.

GMI Gets a Week with the Volt

For all of you followers of the Volt, the online GM media tracker GMinsidenews.com got a week with Chevy's lime lit electric vehicle. The consensus is, not surprisingly, that it's a great car, and a very worthy adversary of the Leaf and Prius. The author of the article, Nick Saporito—an editor for the online company, thoroughly enjoyed driving the Volt. He writes about how well it charges, how it handles and the changes in lifestyle that owners and hopefully employers would benefit from making in their daily routines and buildings. Here's the article in full and what he had to say:

Living Electric: 2011 Chevrolet Volt
Living with the revolutionary Volt doesn't require revolutionary changes.
www.GMInsideNews.com
July 22, 2011
By: Nick Saporito

Having already spent time behind the wheel of Chevrolet's extended range electric vehicle, I knew what to expect. I expected a vehicle that — despite being a technological marvel — is a very livable vehicle that does not fundamentally alter the driver's daily life. And to a large degree, living with a Volt for a week left me with some very predictable opinions.

Perhaps the biggest change one should expect when driving the Volt has nothing to do with the car's technology but everything to do with its image. Living in the Midwest, far from any of Volt's initial launch markets, I felt like I was piloting a rock star. From the carhop at Sonic to random store parking lot patrons, the car got an immense amount of attention. Even the local GM dealership had to check out the Volt.

Having driven a variety of new vehicles, many of which are designed to be attention-getters, none captured the amount of attention the Volt got. Though the Volt's design is quite attractive for a small car, I think a lot of the attention is instead based on the fact that many people are pleased to see the "home team" generate a car that is both technologically mighty and socially responsible.

Going from my gas-only Pontiac G8 to the Volt did lead to one small change in my garage layout. There are no electrical outlets on the driver's side (of that parking spot), so in an effort to prevent running electrical cords all over, the Volt was parked on the other side. We find it likely that many Volt owners will have to modify their garages to some degree, either by changing parking spots or installing new electrical outlets.

In the back of every Volt is a 120-volt charger for the car. This was the only charger we could utilize with our test car. The charger itself is fairly compact, about the size of a small shoebox. The 120-volt charger does its job well, but the nearly 10-hour charging time (from a completely drained battery) is perhaps not ideal. During the first few days with the Volt we could not get it to 100-percent charge, largely due to the fact that this reviewer rarely ever stayed out of the car for 10-hours straight.

Another charging note is that this particular Volt liked to honk the horn frequently while charging. The honk was fairly subdued and I later found out from the owner's manual that it was honking because charging was stopping momentarily, then restarting. Despite further research, I never was able to determine what ceased the charging, but it is worth noting that at times the car was charging in extremely hot conditions. The battery fans were almost always running while the car was charging at night. Neither the honking nor the fan noises were ever loud enough to disturb anyone in the house, even in an attached garage.

Volt owners can (and should) opt for the 220-volt charger. The upgraded charger has to be hard-wired into your home's electrical system, meaning professional installation is a must for most. The beefier charger reduces the charge time to less than half of that required by the 120-volt charger.

One issue Volt owners are likely to run into is their employer, should they desire to charge the car at work. During my week with the car it became clear that there were virtually no parking spaces at my employer designed for an electric vehicle. Perhaps that is the beauty of the Volt - it does not have to be charged all the time.

My thoughts on driving the Volt are already on record, and living with the car only amplified my initial thoughts from last year's media drive. The car is tremendously fun considering its main purpose is as an "eco friendly" form of transportation.

During the week-long test, it was difficult for this reviewer not to drive the Volt in sport mode almost continuously. Many cars have various drive mode settings, but only the Volt's is so drastically different from normal mode. The improved acceleration is obvious and downright fun.

Really the only pitfall from a performance perspective is the car's slick, fuel-economy-enhancing tires. A set of stickier rubber would complement the Volt's already surprisingly fun-to-drive package.

Stopping to unplug the car every morning to depart on my commute was a small novelty that, frankly, was kind of cool. Even better was the fact that charging the Volt only cost $1.00 per day on my electric company's rates. Shelling out that $1.00 was a far cry from my normal $60.00 haul at the fuel pump with my personal car.

Another novelty that comes with the Volt is the car's pedestrian alert chirp. While a serious feature with serious uses, I can't lie… it was entertaining to chirp the car when people were already checking the car out as I drove by.

During my week with the Volt I burned only 3.4 gallons of fuel, ultimately yielding in excess of 100 MPG with the car. It is worth noting that I charged the car every night (which was not always to 100 percent) and took the car on three road trips that required extended range mode.

My Volt tester was the 420th Volt built according to the car's infotainment system. Every Volt keeps track of its lifetime fuel economy rating, and this particular tester's lifetime fuel economy average was around 50 MPG, which likely includes a lot of long-distance trips considering the region of the country it is utilized in.

Overall, living with the Volt is much as expected: simple. Future Volt owners are likely going to have to adapt their garages and beg their employers to install charging stations to avoid the fuel pump at all costs. Other than that, owners are getting an eco-car that would run circles around the arch rival Toyota Prius both on the race track and runway.

2011 Chevrolet Volt
MSRP: $43,390 (The first 250,000 Volts sold can qualify for a $7,500 Federal Tax Credit)
EPA Ratings: 93 eMPG / 37 MPG Gas Only
Observed Fuel Economy: 102 MPG (electric/gas combined)
Test Car Historical Average: 50 MPG (electric/gas combined)

Pros: Electric car without much hassle, simple to drive, fun to drive.

Cons: Charging takes awhile, will likely require garage/employer modifications, still pricey technology.

Nissan Leaf Ad Strikes at Chevy Volt


For those of us in the Chevy community quietly watching our beloved matriarch pull herself up from the ashes of bankruptcy, some of the others in the car community make it a point to point out some of her shortcomings…even when the shortcomings are worldwide problems. The makers of the Leaf- Nissan; in their latest advertisement for their 100% electric vehicle have taken it upon themselves to point out that the Volt still needs to be fueled with traditional gasoline. Although this is not an unknown fact to any consumer who has taken the time to research the Volt, it is not its primary selling point…Hence the name Volt. But before we go into a full on rant about why Nissan shouldn't have let that commercial air, and how Chevy is doing its best—let's take a look at the competition a little closer.

When we really break it down between the lower-end hybrid competition, who really wins? Is it the harshly marketed Nissan, the Americans, or another competitor? We decided to leave out the Lexus GS Hybrid, and the Tesla Roadster as the market for those cars is aimed at a higher income demographic than what we're examining. Keep in mind however, the average right now for gas in the US is $3.84 a gallon and if you drive 250 miles

a week (assuming you get 22 mpg on average in your current vehicle), that's $177 spent a month on gas. If The Dude were to have anything to do with this analysis, he might say, "There's a lot of ins, a lot of outs, new stuff has come to light, man." The four we'll pick apart in the shorthand of online journalism are obviously the Chevy Volt and the Nissan Leaf but then we'll stick them against the long time running Toyota Prius and Honda Insight.

First, let's take a look at Chevy's pride and joy—the Volt. The Volt has a 1.4L DOHC inline four, with a Lithium Ion (Li-ion) rechargeable battery system that operates two motors—a 111 Kw drive motor and a 54 Kw generator motor. The fully charged battery can take the Volt 25-50 miles depending on the terrain, driving habits and external (ambient air) temperature. So, the sum of this put together gets the occupant an estimated 370ish miles when combined with the gasoline engine; all said and done, a 38 mpg average. Not too shabby. The sticker for the Volt is $41,000 when it's "competitively equipped" according to Chevy.

Nissan's Leaf is a completely electric vehicle, with no gasoline engine. The range for the Leaf on a full charge is a claimed 92 miles, but in actuality it usually falls within the 60-70 mile range before being depleted especially if you run the A/C and live in an area with traffic—just like stop and go traffic burns significantly more gas in a traditional car/engine set up—it bears the same burden on a battery. The charge time of 7-8 hours for a full charge on 220 volt outlets is also somewhat of a hindrance, although there is a quick charge option that can be achieved in roughly 30 minutes to charge the battery to 80% but repetition of this process will harm the battery over time. While a great cause for promoting zero-emissions, it won't do you any good if you have to travel any great distance, but as an "around town" car it would be great. The price tag for this puppy clocks in at $33,720. For a zero-emission commuter it seems like an excellent option…but it does bear the question, how much would it cost to charge? My immediate thought went something like this, "If I ran the clothes dryer (also uses 220v outlet) for 7-8 hours a day, my electric bill would skyrocket!" Not so. In Atlanta, where a KwH is 11.3 cents an hour, the required 22 KwH's of charge the Leaf requires equates to $2.49. Even if you had to fully charge the car every night (meaning you had run the battery down to "Empty" every day), you're looking at adding $77 a month to your electricity bill. Considering this is your gas bill for the month, not too bad. In fact, that's $100 less than what the current average for gas costs per month are.

The Toyota Prius has a 1.8L DOHC inline four (a .4L increase over the Volt), with a Nickel Metal Hydride (Ni-MH) battery operating an electric motor/generator that puts out 60 Kw (80 HP), for a combined total of 134 horsepower. The Prius doesn't have the option of running on one or the other however- it is a constant combination of both. The Prius has an 11.9 gallon fuel tank and gets an EPA estimated 571 miles to the tank for an average of 48 miles to the gallon. The way the Prius works is like this: when pulling away from a stop or under a light load, only the electric motor powers the vehicle. In normal driving, power from the gasoline engine is divided by a power-split device between the wheels and the electric generator. The generator runs the electric motor to provide additional power to the wheels. Under full-throttle acceleration, the electric motor is supplemented by power from the batteries. During deceleration or braking, the motor functions as a generator to recharge the batteries. The batteries never need to be recharged from an external source. The gasoline engine also shuts down, creating zero exhaust emissions and using no fuel. The battery is regulated to maintain a constant charge. When the charge is low, the electric generator routes power to charge the battery. The Prius has a "competitively equipped" MSRP of $28,790 for the Prius 5—the top end model.

Last but not least, we have the Honda Insight. Clocking in right at $21,490—this is certainly the cheapest option for the crowd. It is powered by a 1.3L SOHC 8-Valve inline four that is coupled to an electric motor on the crankshaft of the engine. The motor acts as a generator during braking, steady cruising, gentle deceleration and coasting in order to recharge the battery. The motor also serves as the engine starter, quickly spinning the

engine to idle speed after Idle Stop and during normal vehicle starting. The system will automatically switch to a back-up, conventional 12-volt starter to start the engine if the IMA (generator) system is disabled or if the car is started at extreme cold temperatures. As an additional safety feature, Honda's hybrid configuration allows the car to operate like a conventional, gas-engine vehicle even if the hybrid-electric motor system is completely disabled. The Insight has a 10.6 gallon fuel tank and its EPA estimated highway mileage is 456 miles to the tank, or 43 mpg.

So, let's break this whole thing down and list the cars by most efficient first, then take the list again and organize it by price. We can obviously say that the Leaf is the greenest car out of the bunch with zero emissions, but at the same time is severely limited by range and its recharging capabilities making it the least practical. In order to place the cars on the list by order of efficiency we'll (for arguments sake) place them with fuel economy as the highest priority.

With the Leaf not using standard fuel, and being fully electric—it takes number one, followed by the Toyota Prius @48 mpg, then the Honda Insight @ 43 mpg, and lastly putting the Chevy Volt @ 35 mpg at the bottom of the list. However, since the Chevy Volt can be driven roughly 35 miles on nothing except electric power that alters the standings and could place the Volt in second.

This is what The Dude was talking about.

However if we were to arrange the cars by distance that could be achieved on a single tank/charge the standings dramatically change. The Prius takes first with 571 miles to the tank, the Honda Insight takes second at 456 miles, the Volt third at 372 miles and lastly the Nissan Leaf which is limited at best to 92 miles before needing an outlet to recharge.

Once again though, if we take the price tag as the main point of concern and rank them from cheapest to most expensive the tables turn again. The Insight from Honda takes first with a tag at $21,490; the Prius takes second at $28,790; Nissan hails for third at $33,720; and clocking in with a price nearly double the Honda comes the Chevy Volt with a $41,000 sticker on it.

Obviously this is Chevy's first attempt at the Electric Vehicle market, and they're trying hard to fit in. They need the Volt to do well, as they have invested millions upon millions into the Volt, telling project managers that they could have as much manpower and resources as they saw fit. The "blank-check" that upper GM management gave the Volt project was obviously given with the assumption that they would make back a large chunk or more than what they put into it. GM has a lot riding on the Volt, and the competition has had a head start with over a decade to figure the game out and set the bar. So, can we expect Chevy to come out with a cheaper version? Almost certainly. Can we expect an improved version, or luxury version, perhaps even a different platform? Absolutely. The big guys upstairs at GM were really pushing to have the Volt released as soon as physically possible, and not that it wasn't an enormous feat, but they have room to improve—which is always a good thing. If an American car company can make a reliable, efficient, and viable EV competitor in the worldwide market, then they might have just found a ticket to financial freedom. If however they don't pull the Volt off, and if it proves to be a flop, then GM has some big issues that they'll have to figure out how to sort out. Regardless of the competition, the Volt is a great looking car and deserves a special place in GM's collection. The Volt is a milestone for GM and proves they're incredibly serious about its production and improvement. Good on ya GM.
