Seriously Dramatic In Generation Powertrain Changes

Almost every brand these days has mastered the mid-cycle facelift. A quick update or two a little more than half way in to the product's lifespan to keep the model fresh and the newer competition at bay. Often this yields little more than some new lights, bumpers and other easily changeable pieces. It's rare to see significant powertrain changes for the mid-cycle facelift but occasionally automakers will have a strong urge to yank out the old and put in something completely different. At times patience runs out even before the scheduled facelift. Here are a few of the most dramatic "in generation" powertrain changes with some surprising and amazing results.

Mercedes Benz E55 to E63 AMG

It's especially rare to see an engine change for a high performance version considering the limited volume at play but that is exactly what Mercedes did when it went from a supercharged 5.4 liter V8 to a sweet sounding naturally aspirated 6.3 liter V8 for the last generation E Class AMG.

Hardest Working Powertrains In the Business

As with sports teams, smartphones and cars in general, not all horsepower ratings are created equal. The more instrumented tests you see the clearer it becomes that 200 horsepower from one brand does not necessarily result in the same performance as 200 horsepower from another. There are certainly some serious underachievers in the industry but for now let's keep it positive and take a look at three of the hardest working powertrain combinations (in alphabetical order) that make a mockery of physics and their competition.

Audi S6 4.0T V8

The current Audi S6 dropped a pair of cylinders and 1.2 liters of displacement between generations. It did gain a pair of turbos but on paper it lost 15 horsepower and gained only an irrelevant 8 lb-ft of torque. On paper the S6 represents a rare case of a new generation delivering less horsepower than before, something almost unheard of for a performance model. Thankfully, the S6 is an overachiever for the ages with magical turbos, all wheel drive grip and a dual clutch gearbox with launch control working in tandem to knock of nearly two seconds (3.7) from the sprint to 60 and add 11 mph (115) in the 1/4 mile trap speed versus the previous generation. It's one thing to compare models 6 years apart but let's see how the 4.0T compares to its contemporary competition. The Cadillac CTS Vsport brings the same 420 horsepower, more torque and less weight to the table yet it's almost a second slower to 60 and about 2.5 seconds to 130. The CTS Vsport is no slouch but it's hard to believe that the S6 is only packing 420 horsepower when it delivers performance on par with the 556 horsepower CTS-V.

Best Non Exotic Exhaust Notes

You are walking down the street and all of a sudden someone turns the corner and gives it some gas and you hear a glorious sound that makes you turn around to see if you can guess correctly what it is. Every so often you turn around and see an exotic that surprises you but more often than not it's something a little more ordinary. Below are some of the best exhaust notes from cars that you can spot on a regular basis.

Mercedes-Benz C63

The AMG 6.2 liter V8 that powers 63 series AMG models is on its last legs as it is replaced by smaller turbocharged V8 engines. Lauded for its excellent power the naturally aspirated V8 is one of the best sounding engines this side of super cars and exotics. The AMG V8 has the perfect balance between a low rumble of an American V8 and that of a higher revving European V8 which makes it a hard combination to beat.




Mustang V8

The Mustang has always had a fantastic V8 sound even when the 4.6 liter V8 was barely stronger than some V6s at the time. Nevertheless, Mustang V8s almost always deliver a fantastic rumble that while not as high revving as the AMG V8 does rev a little higher than your traditional American V8 giving you more glorious sound through the rev range. While the latest 5.0 cammer sounds fantastic one of my favorites is the 2003-2004 SVT Cobra that is always one of the louder street legal cars that you will spot as most are usually modified.




Audi V8

The now nearly retired Audi 4.2 V8 is another fantastic sounding V8. Most often found in the last generation S4 and the pre face lift S5 the 4.2 also has some additional revs to play with as well for a throaty sound across the entire rev range. The 4.2 also sounds pretty good in the Q7 but is far too quite in the A6 and A8 versions. Much like the AMG V8 the naturally aspirated V8 is being replaced in all but its high power version by the smaller supercharged V6 that delivers more power but lacks the sound.




To balance out all of the amazing exhaust notes one can hear on a daily basis there is always one sound that drives me insane, the various versions of the Infiniti 3.7 V6. The VQ's pitch just doesn't sound right to me especially at lower RPM and the worst offender is the FX version that always produces a loud drone even when accelerating at an extremely pedestrian pace.

Plymouth Prowler Retrospective: Could Have Used a V8

There are some things in life that go so well together that they are famous for being together; peanut butter and jelly, mac & cheese, burgers and fries and so on. Hot Rods and V8s go together just as well, ever seen a Hot rod without one? As a modern take on the Hot rod the Plymouth (and later Chrysler) Prowler certainly had the styling to look like one, but lacked the horsepower and the requisite V8 to truly be one. For these and other reasons some saw the Prowler as a disappointment, Time magazine even rated it as one of its 50 worst cars of all time. With that in mind let's take a look at the Prowler's legacy and see what this unique vehicle was all about. We'll compare the Prowler to its contemporary competition in areas of styling, performance and value to see if it really deserves to be called one of the worst of all time.

Design

Certainly the Prowler looked and still looks like nothing else on the road today. If you disagree, ask yourself when was the last time you saw Formula 1 style wheel and suspension combination? The Chip Foose inspired Prowler draws attention with classic Hot rod proportion, wider and higher at the rear than at the front. Looking sleek and wide the Prowler looked great with its 17 inch wheels upfront and 20 inch wheels at the rear at a time when no one else was even thinking of 20 inch wheels. The 20 inch wheels were not the only mechanical element ahead of its time; aluminum construction gave the Prowler a relatively light curb weight of around 2,800 pounds. Upfront inboard mounted shocks handled suspension duty. The Prowler also used a rear mounted transmission as seen on the Corvette. The 4 speed automatic transmission was connected to a 3.5 liter V6 upfront. Overall the Prowler certainly looked like a performance Hot Rod and had some trick technology to boot.

Powertrain

Before we begin this section it's important to consider that it's been over a decade now since the Prowler stopped production so the horsepower numbers of that time period will look tame all across the board. Chrysler's decision to adapt its LH sedan powertain components (of 300M/Dodge Intrepid fame) has certainly been questioned by many critics. The Prowler first used 3.5 liter V6 with 214 horsepower which was updated for the 1999 model year to 253 horsepower and 255 pound feet of torque. At the time the Chrysler V6 was around 30 horsepower more powerful than any other mainstream V6 from Acura, Lexus or even BMW's inline six in the 5 series. At the time the most powerful Porsche Boxster had a 250 horsepower 3.2 liter flat six while the non M BMW Z3 topped out at 230 horsepower. On the domestic front the C5 Chevrolet Corvette produced 345 horsepower from its then new LS1 V8. Chrysler on the other hand did not have a powerful V8 option to consider. Its most powerful V8 at the time, the 5.9 Magnum, produced 250 horsepower (torque was greater @ 345 lb-ft), essentially ruling it out as a performance improvement over the V6. The LS1 challenging Hemi would not go on sale until after the Prowler ceased production. Based on the lack of a powerful V8 available at the time Chrysler's decision to use a "parts bin" sedan V6 was reasonable and financially sound, but hindsight would indicate that something like a V8 version of the Viper V10 would have made the Prowler a true modern day hot rod.

Performance

While the Prowler lacked a V8 soundtrack (the V6 was quite loud though) and was limited by a four speed automatic gearbox its acceleration performance was not too bad for its day but slightly slower than its competitors. The Prowler accelerated to 60 in 6 seconds flat or about the same as the regular Boxster but around half a second slower than the BMW Z3. More expensive competition like the Corvette, BMW M Roadster, Mercedes SLK 320AMG all featured more power and were about a second and a half quicker to 60. Despite its light weight the Prowler was not known for great handling being more of a cruiser than a sports car.

Value

By using "parts bin" components for the powertrain and the interior Chrysler was able to keep Prowler's price to a competative level between 40-45,000 dollars throughout its life cycle. Closest convertible competition such as the Corvette convertible, BMW Z3 Mercedes SLK320 and the Porsche Boxster were priced in a similar price range, between 38-45,000. While the Prowler enjoyed a competitive sticker price dealer markup of 10,000 or more was abundant during the first few model years indicating the public's interest in the Prowler.

The final tally of 11,702 Prowlers produced tells much about it as a vehicle. Featuring styling that turned heads like nothing else except a few Italian exotics it was not for everyone. A V8 would have made it that much more desirable but it's certainly can not qualify as one of the 50 worst cars of all time under any circumstances.

Future Audi S6 and S8 Engines Revealed

Audi just recently unveiled its brand new A6 and the A8 has only been on sale for a few months, but the brand is soon to augment its lineup up with high performance S models. Long rumored to receive a turbocharged V8 to replace the naturally aspirated V10 of the previous generation we can now confirm the horsepower output of the S versions. The S6 and S8 will both feature a 4.0 TFSI engine, the S6 will have 408 horsepower while the S8 will have 518 horsepower. It's likely that the S6 (and S7) will use a single turbocharger while the S8 will rely on a twin-turbo setup to deliver the extra 110 horsepower. The S6 will use a 7 speed dual-clutch gearbox while the S8 will have an 8 speed auto. The regular A8 will also use the 4.0T, delivering 420 horsepower in that application. The S6 and S8 are set to go to production towards the end of 2011 so expect a public debut soon. In related news the new A6 will also receive the long expected twin-turbo 3.0TDI engine with 313 horsepower in August.

The last generation S6 and S8 also shared a common engine, the 5.2 liter V10, but with a much more similar state of tune. The S6 V10 made 435 horsepower while the S8 made 450. This time it appears that the S6 will be repositioned in the same manner as Audi has done with the S4 previously. The S6 will become the sole V8 option (until the RS6) in the A6 lineup much like the S4 is the only V6 option for the A4. And for those concerned with the horsepower drop from the V10 I suspect that the new S6 will easily outperform its predecessor much like the latest supercharged V6 S4 had done compared to the old V8 powered S4.

Chicago Day One Recap

Day one at the Chicago autoshow is over and the emerging trend is high horsepower V8s. Going against the grain of the past few autoshow seasons Chevrolet, Dodge and Hyundai dominated day one with their new performance offerings. Chevy introduced the ZL1 version of the Camaro with a supercharged 550 horsepower/550 lb-ft of torque LSA V8. The highest performing Camaro of all time also receives the expected agressive exterior enhancements along with a beefed-up drivetrain, magnetic ride suspension, and bigger brakes. An all black interior and a dual mode exhaust are also exclusive ZL1 features. The ZL1 is set to bring the challange to the Mustang GT500 in about a years time.



Not to be outdone Dodge also unveiled the SRT8 version of its new Charger. Looking a little like a four-door GT-R the latest SRT8 features more unique styling compared to the first generation SRT8. The biggest change aside from the 465 horsepower/465 lb-ft of torque 6.4 liter Hemi V8 is the large blacked-out Evoesque grille upfront. The SRT8 also receives unique 20 inch wheels, Brembo brakes, a larger rear spoiler, and heavily bolstered seats. Dodge predicts high 4 second 0-60 time along with a 1/4 mile time in the high 12 second range when the Charger goes on sale this fall.



Rounding out the day was a yet another V8 powered sedan, the Hyundai Genesis R-Spec. The Genesis R is the first application of Hyundai's new 5 liter direct injected V8. The 429 horsepower/376 lb-ft V8 will be paired up with a new 8 speed automatic in the 2012 Genesis which also receives new Audiesque LED daytime running lights, updated tailights and restyled fascias. Hyundai also promises to up the sport factor on the R-Spec with bigger stabilizer bars and brakes, and recalibrated steering.

EcoBoost V6 F-150 To Tow More than Competitor V8s

Ford says that its 2011 F-150 equipped with the twin-turbo 3.5 liter EcoBoost V6 will tow up to 11,300 pounds, giving it more towing capacity than even the V8 powered competition. Payload capacity likewise tops the competition with 3,060 pounds. Even though the EcoBoost V6 outshines the competition it is still only the second strongest engine in the 2011 F-150 lineup with 365 horsepower and 420 lb-ft of torque. The top dog engine will be the 6.2 liter V8 that first debuted on the Raptor, it produces 411 horsepower and 434 lb-ft of torque. Also available on the 2011 F-150 is the Mustang sourced 5 liter V8 making 360 horsepower and 380 lb-ft of torque in this application, rounding out the engine lineup is a 3.7 liter V6 with 302 horsepower and 278 lb-ft of torque. Ford is promising the 2011 F-150s to deliver 20% better fuel economy than the 2010 versions. It will be interesting to find out how the different engines compare in fuel economy once the ratings become official.

The EcoBoost appears to be a very enticing proposition on paper, but only time will tell if pickup buyers will take a gamble on a high tech engine format previously not seen in their domain.
