Infiniti G37 Review

When Infiniti's first G35 coupe stormed onto the scene in 2002, it proved a worthy alternative to BMW's 3 Series — the best you could get for $35,000 at that time. Now, as the new 3 Series reassumes control of the segment with a rip-snorting 300 horsepower in the 335i, it seems time for Infiniti to hatch the latest G.

That the redesigned G35 sedan already provided a compelling alternative to the 3 Series didn't matter. Infinitidecided against matching that car's 306-hp, 3.5-liter V-6, instead building a 3.7-liter engine for the appropriately named G37 coupe. The larger V-6 sends an estimated 330 hp to the rear wheels through a five-speed automatic or six-speed manual transmission.

Three trim levels are available: base, Journey and Sport 6MT, which is sold exclusively with the manual. Infiniti G37s hit dealerships in August 2007.

Exterior
The G37 looks much like you'd expect for a two-door offshoot of the new G35. The curvaceous body integrates large — but fairly subtle — fenders, while the bumper boasts one of the more sinister interpretations of the familiar air dam and side portals you see on many cars. Twin L-shaped headlights flank the slatted grille. The taillights aren't all that different from those on the previous G35 coupe.

Adding the Sport package to a G37 Journey gets you a sport-tuned suspension, exterior ground effects and massive 14-inch front disc brakes — the same size as those on a Corvette Z06. The Sport package also swaps the G37's standard 18-inch alloy wheels for 19-inchers. The G37 Sport 6MT includes all the enhancements standard.

Infiniti's 4-Wheel Active Steer system is optional on the Journey and 6MT. It turns the rear wheels as well as the front ones, which purportedly improves high-speed handling and makes it easier to turn at parking-lot speeds.

At 183.1 inches long and 71.8 inches wide, the G37 is nominally bigger than the 335i coupe. It's even a bit wider than the G35 sedan.

Interior
Apart from having a smaller backseat with room for two instead of three, the G37's cabin is not much different from that of the G35 sedan. The coupe's interior is a vast improvement over the first-generation G35, and now features such novelties as aluminum trim modeled after Japanese Washi paper.

Standard features include power front seats, automatic climate control, a six-speaker CD stereo and leather upholstery. Heated seats with power side bolsters, a moonroof and a navigation system with real-time traffic monitoring are optional.

Under the Hood
Sporting an elaborate air induction system similar to (no surprise) BMW's Valvetronic, the 3.7-liter V-6 makes an estimated 330 hp and 270 pounds-feet of torque. It teams with a five-speed automatic transmission in the G37 base and Journey, while the Sport 6MT gets a six-speed manual. Cars with the Sport package include a limited-slip differential for better traction while cornering.

Infiniti estimates that the G37's engine actually delivers around 1 mpg better gas mileage than the 3.5-liter V-6 in the G35. With the EPA's revised fuel economy ratings for 2008, that should translate into roughly 21 mpg in combined city and highway driving for a manual-equipped G37.

Safety
All G37s come standard with six airbags, including side-impact airbags for the front seats and side curtain airbags for both rows. Active head restraints, four-wheel-disc antilock brakes, traction control and an electronic stability system are also standard.

Infiniti's Intelligent Cruise Control, which can match highway speeds with the car ahead, is optional. It includes a Preview Braking function that preloads the brakes for faster response if the car in front slams on its brakes. Also optional are pre-crash seat belts that can tighten in response to emergency braking, as well as adaptive headlights that can swivel several degrees to better illuminate corners.

Jaguar XK-Series Review

The Jaguar E-Type or XKE is widely regarded as one of the most beautiful, iconic cars of all time. Introduced in 1961, it has been lusted after ever since, appearing on teenage boys' bedroom walls, grown men's garages and in movies like the "Austin Powers" series, where it served as the international man of mystery's Shaguar. More than three decades since the XKE went to cat heaven, its spirit lives on in a new breed of sleek Jaguar coupes and convertibles. The latest Jaguar XK-Series maintains classic design cues like the oval grille, but adds a thoroughly modern all-aluminum body and high-tech features designed to better defend Britain against German competition.

Lamborghini Gallardo Review

Although it's probably difficult for most people to think of a nearly $200,000 automobile as "affordable," that's the position the Lamborghini Gallardo coupe and spyder convertible find themselves in within the Lambo product lineup. But no matter -- sports cars with exotic looks and the performance to match have a built-in ownership audience.

2007 Lamborghini Gallardo Coupe Shown

Since its introduction, the mission for this "baby Lamborghini" has been to maintain the style and attitude of Lamborghini's 12-cylinder cars but be more livable in everyday use. It's been a successful strategy, as there's been no shortage of takers who rightly lust after such a usable and alluring sports car. In fact, the Gallardo has become this Italian automaker's best-selling model ever.

In terms of layout and design, the Lamborghini Gallardo is a true exotic. There's a mid-mounted V10 engine, all-wheel drive and the availability of an F1-style transmission. To keep weight down, the chassis is a composite blend of alloy stampings, extrusions and castings. And except for the traditionally opening steel doors (no scissors), the exterior is constructed of thermoplastic-formed panels.

Inside, the Gallardo's handsome furnishings sublimely marry form with function and offer a surprising level of comfort for a vehicle of this type. Credit is certainly due to the influence of parent company Audi, whose expertise with interior design has been of no small benefit since the Volkswagen Group purchased Lamborghini in the late 1990s.

Without too much difficultly, one can claim that the Gallardo is Lamborghini's best sports car ever. If there's anything lacking, it's the outrageous spirit and flair so often associated with the company's more expensive or legendary offerings. But the trade-off of a little spirit for a lot of functionality has been a good one, and there's no doubt that the Gallardo is a true, world-class exotic.


Current Lamborghini Gallardo

The exotic Lamborghini Gallardo is currently available as a coupe or spyder convertible, with the coupe available in two trim levels: base and SE. Standard equipment includes 19-inch alloy wheels, xenon headlights, fully powered accessories and a CD audio system. A winter package adds heated mirrors and seats along with winter tires and specific wheels. A sport suspension, navigation system, carbon-ceramic brakes and rear back-up camera are also available. In keeping with its pedigree, the Gallardo's trim and paint can be further customized, too. The limited-production SE is similar to the base coupe mechanically, but has a specific two-tone color treatment and includes as standard equipment some of the base car's optional features.

A new addition for 2007 is the Gallardo Superleggera. This coupe-only model has been modified for even better performance. It features 10 additional horsepower, slightly different suspension settings and an approximate 150-pound-lighter curb weight thanks to extensive use of carbon fiber and reduced feature content.

For optimum dynamic balance, the 5.0-liter V10 engine is positioned just aft of the driver. It develops 512 horsepower (522 for the Superleggera) and 376 pound-feet of torque. Power is sent to all four wheels through a six-speed manual transmission. An automated, sequential-shifting manual "e-gear" transmission is also available, which can be placed in an automatic mode or shifted via steering-wheel-mounted paddles. Antilock brakes, traction control and stability control are standard safety fare, as are head-protecting side curtain airbags.

Audi's influence is obvious inside the Lamborghini Gallardo, with plenty of precisely fitting leather and soft-touch materials. Despite the fact that this is an exotic sports car, seating is comfortable enough to accommodate the occasional road trip. Though not as flamboyant as its extroverted exterior, the interior styling still befits a vehicle in this price range. Storage space is tight, though, with a minimal amount of room available behind the seats and in the nose-mounted trunk.

But once behind the wheel, you'll gladly leave everything behind in exchange for the sweet, sonorous symphony of its V10 at full throttle. With more than 500 horses at your command, the Gallardo is capable of spine-compressing speed in any gear. The big V10 and all-wheel-drive system do add quite a bit of mass, so it doesn't deliver the razor's-edge responsiveness of some of its rivals. And the powerful brakes can feel a bit inconsistent at the limit. But there's still plenty to like about the Gallardo. Its gearing practically begs you to rev the V10 for all it's worth, and its AWD system certainly gives it a clear advantage for safely wringing out maximum performance when the road ahead is slick and unfamiliar.

Past Lamborghini Gallardo Models

The Gallardo coupe debuted in 2004. An expanded lineup arrived in 2006 featuring the addition of the spyder convertible with an automatic folding soft top and the SE model featuring two-tone color treatments and a host of mechanical updates that ultimately extended to the regular Gallardo as well.

Mazda RX-8 Review

Most people know that Mazda builds sporty cars. But for driving enthusiasts, it's the company's history of building sport coupes with lightweight rotary engines that sets it apart from the competition. The Mazda RX-8 is the latest of these coupes, and it's the only one with a four-door configuration.

2008 Mazda RX-8 Grand Touring Coupe Shown

The heart of the Mazda RX-8 is its high-revving, 1.3-liter rotary engine called the Renesis. It's a made-up word: The "R" and the "e" stand for "Rotary engine," while "nesis" comes from the word "genesis." Odd name aside, the Renesis engine is an impressive bit of engineering: Unlike its forbears, it locates the exhaust ports on the side of each of the combustion chambers, rather than on the outer edge of the rotary housing. Sounds simple, but this one change allows for more power, higher fuel economy and lower emissions.

Because of the engine's compact size, engineers were able to mount it further back in the RX-8's chassis, giving the car a coveted 50/50 front/rear weight distribution. This, along with balanced suspension tuning, sharp steering and a svelte 3,000-pound curb weight, makes the rear-wheel-drive RX-8 one of the best-handling cars on the market. It's certainly among the best sports cars available for less than $30,000, and deserving of any consideration you give it.

Introduced for 2004, the Mazda RX-8 heralded the return of the rotary-powered sports car to the U.S. after a near decade-long hiatus. It also gave Mazda an image car with greater stature and performance credentials than the fun-loving Miata. Although the RX-8 hasn't been a runaway sales success, most people would agree it's been good for the company's reputation.

Although Mazda sells its sport coupe with either a manual or automatic transmission, the six-speed manual version is really the only way to experience an RX-8. It's not just the closer connection you feel to the car when moving the short-throw shifter among the neatly defined gates. It's the fact that manual-shift RX-8s get a more powerful version of the 1.3-liter rotary engine.

In a manual-equipped Mazda RX-8, horsepower crests at 238 at 8,500 rpm, with redline hitting at an amazing 9,000. Low-end torque has never been a strong suit of rotary engines, and with a mere 159 pound-feet coming together at 5,500 rpm, the RX-8 doesn't really feel potent below 4,000. Fortunately, the rotary engine loves to rev and is very smooth when doing it.

Inside Line testers have timed the RX-8 at 6.6 seconds to 60 mph and 15.1 seconds through the quarter-mile -- respectable numbers but not enough to win many straight-line acceleration crowns in this class. However, Mazda's rotary coupe quickly makes up ground when the road turns curvy.

Automatic RX-8s are tamer, redlining at just 7,500 rpm. If you're going to buy one, 2006 and newer models are your best bet, as they come with a more advanced six-speed automatic transmission with steering column-mounted paddle shifters. They also provide 212 hp at 7,500 rpm, compared to 197 in the '04 and '05 models, which came with a four-speed automatic.

In spite of its capability, the Mazda RX-8 rides comfortably enough to serve as a daily commuter, though with fuel economy typically hovering in the high teens, it's not the most economical choice. The rear seats are roomy enough to seat adults on short trips, and reverse-hinged rear doors allow the loading of bulky car seats.

RX-8s come standard with all the essential amenities, though manual versions come with a firmer suspension and 18-inch wheels, which are optional on the automatic. Further suspension upgrades are available via the Shinka special-edition package. You can also add luxuries like leather upholstery and a navigation system.

Although it has an extra set of doors, the Mazda RX-8 is a descendant of the two-door RX-7 sport coupe sold in three generations from 1979-'95. The RX-7 was yanked from the U.S. market due to poor sales and difficulty in meeting emissions standards, but lived on in the Japanese market through 2002. At the time of its U.S. demise, the third-gen RX-7 was a much more expensive car than today's RX-8, with a base price of $32,500 in 1995 dollars.

That's not to say it wasn't worth the extra money. Sold from 1993-'95, this model was turbocharged and capable of 255 hp at 6,500 rpm and 217 lb-ft of torque at 5,000 rpm. Zero to 60 took just 5.5 seconds, with the quarter-mile mark coming in 14 seconds flat. Not only was it fast, it was a superb handler, often inspiring comparisons to Formula cars. Harsh ride quality was the big downside. This car fetches high prices on the used market, though potential buyers should be attentive to excessive wear and tear and aftermarket modifications made by the previous owner.

Mercedes-Benz SLR McLaren Review

South Africa might seem a strange place to launch a 200-mph exotic sports-GT car that will find owners mainly in the U.S. and western Europe. More so when you consider that the most significant achievement by an SLR model was in Italy, at the Mille Miglia event of 1955. But Mercedes-Benz 
has conducted operations in South Africa for more than 45 years, including complete vehicle assembly. More important, the weather in mid-November is fabulous.

Piloting these left-drive-only coupes in a right-hand-drive market took only a short adjustment, leaving us free to enjoy the SLR’s addictive power against the spectacularly scenic backdrop of the Cape mountains. The audio soundtrack wasn’t bad, either, with a muted but shrill scream of a twin-screw Lysholm blower accompanying a distinctly staccato roar from the 617-hp V-8’s side pipes every time the driver stabbed the pedal.

Each of the engine’s cylinder banks enjoys a stream of condensed intake air from separate intercoolers, together producing a torque curve quite similar to the profile of Cape Town’s Table Mountain. There is already 440 pound-feet of torque by 1500 rpm, and well over 500 pound-feet between 3000 and 5000 rpm. This lends mind-boggling elasticity to the SLR, with passing performance that has to be felt to be appreciated.

We’ve become fairly accustomed to huge output from AMG-built engines, but most of those are housed in conventional steel models weighing quite a bit more than the 3800-pound, carbon-fiber-bodied SLR. This isn’t exactly svelte when one considers that carbon fiber weighs half as much as steel. Mercedes claims 3.8 seconds for the 0-to-60-mph scramble, and we think that might be a conservative estimate.

The carbon-fiber structure, produced in an all-new facility in Woking, England, is the real story of the SLR, and it celebrates the relationship between Mercedes-Benz 
and McLaren in the Formula 1 circus. Under McLaren’s management, this new plant conducts the high-tech assembly procedures that will give birth to 3500 examples of the SLR over the next seven years.

This carbon-fiber road car exploits that material’s amazing strength and feathery weight for high performance and safety. The entire body is a composite molding, with beautiful front and rear aluminum subframes bolted and bonded to the tub to mount the engine and undercarriage. Below the tub is a completely flat underbody.

When you flip open the long clamshell hood, it’s a surprise to see how little of the exposed interior is filled by the engine. For optimal weight distribution (the percentage, front to rear, is 51/49), the engine protrudes only two or so feet forward of the base of the windshield. Ahead of that is a monstrous snorkel reaching for cool air rushing in around the three-pointed star.

Other neat features visible under the hood are the forged-aluminum double control arms, along with an anti-roll bar mounted above the suspension and torqued by a Formula 1–style rocker assembly.

At each end of the car are conical crash members made of 25,000 carbon-fiber filaments wound from 48 reels using techniques developed by the textile industry. As exhibits from crash tests proved, these crash members provide remarkable absorption and resistance to impact damage.

The composite body is palpably stiff to the car’s occupants, never emitting a squeak or groan on the worst surfaces, despite a suspension on the firm side. Those A-pillar-mounted gullwing doors—opening to 107 degrees and attracting hordes of onlookers—would undoubtedly betray deficiencies in the structure if there were any.

The inside of the SLR is as exotic as the Batmobile exterior, with carbon-fiber seat shells covered in fine leather and a cockpit built of contrasting colors and textures. To start the SLR, you turn the stubby key, flip a cover at the top of the gear selector, and thumb the button that hides there to bring the 5.4-liter V-8 rumbling to life.

Mercedes’ strongest five-speed automatic (with manual override) still required internal reinforcements to handle the enormous horsepower of the SLR. It offers three levels of transmission performance—comfort, sport, and manual. In manual mode, the box shifts only in response to the wheel-mounted buttons or a side swipe at the selector, and it has an additional three levels of response and shift speeds set by yet another rotary knob.

We like that this manumatic can be made fully responsive to the driver, turning the automatic box into something very like the paddle-shift system in Ferraris and allowing you to hold gears for corner entries and such. We like the electronic braking system less. There’s an initial dead zone in the pedal travel, and one instinctively feels for the usual hydraulic takeup point, whereupon the giant eight-piston front calipers take a firmer bite on the 14.6-inch ceramic discs than you’d planned.


Other than that, the SLR is largely devoid of the syrupy control feel that coats most Mercedes cars. Its steering is deliberate and linear, the power delivery smooth but somehow raw, the ride firm and immediate. There’s quite a bit of grip from the made-to-order Michelin Pilot Sport tires, abetted by a McLaren-tuned chassis and Mercedes-Benz’s electronic stability program, which—for once—has a pretty high threshold. A pity it still steps in so intrusively, but with so much potential and so much value in the car, maybe that’s a good thing.

There were mixed reactions to the SLR’s styling at its first appearance, but the positive response by potential buyers now suggests that every example will find a home.
