2009 VW Jetta TDI Road Test: Turbocharged Torque

Torque is described as a force that tends to turn things and, in the case of the 2009 Jetta TDI, its abundance turned me into a fan of this latest in a long line of Volkswagen "oil-burners" by providing strong performance and flexibility along with exceptionally high levels of fuel economy.

Torque is what you get when you, for example, tug on the handle of a wrench to tighten or loosen a nut. Doing so exerts a twisting force still expressed here, in Ye Olde English, in lb-ft, as nobody on this side of the Atlantic has any idea what a newton-metre is.

Torque in an engine is generated by burning a fuel/air mixture in a cylinder, with the pressure of the expanding gases pushing the piston, which is linked to the crankshaft by a connecting rod, downwards.

As this occurs, the angle generated by the crankshaft "throw" increases and the rod, like the wrench handle above, rotates the crank. And that, with a few things such as clutches and transmission gears in between, is what makes your car move.

The Jetta TDI, with its turbocharged diesel engine, does this with a degree of vigour, accompanied by a high degree of overall flexibility not normally experienced in the compact-car category. Most small-displacement gasoline engines don't produce a lot of torque, and what they do is generated at higher engine speeds.

The TDI's four-cylinder engine delivers a disproportionate (for its displacement) amount of low rpm "grunt" that lets it charge off the line like a V-6 but also maintains that strong pulling power at highway speeds.

This allows it to coast along at minimal revs in top gear while sipping fuel at such a frugal rate that 1,000 km per tank wouldn't be an unlikely achievement. In fact, the number on the trip computer that estimates how much distance I had before needing more gas disconcertingly went up for the first hundred kilometres or so that I drove the car.

The TDI's arrival last year marked the return of the popular diesel engine option to the VW lineup in North America — it hadn't been able to sell a diesel here in 2007 due to U.S. emission standards — and the Jetta range now offers three engine choices, each of which gives the car a different driving character.

There's a gasoline-fuelled, 2.5-litre, four-cylinder that makes 177 hp at 5,700 rpm and 177 lb-ft of torque peaking at 4,250 rpm. With six-speed automatic transmission, it delivers very good performance and fuel economy ratings of 10.5 L/100 km city and 7.2 highway.

Also available is a performance-oriented, gas-burning, turbocharged 2.0-litre unit rated at 200 hp at 5,100 rpm and 207 lb-ft of torque from 1,700-5,000 rpm. This makes the 2.0 TSI Jetta a very quick car indeed and, thanks to the turbo, produces plenty of torque over that wide rpm range, which helps it garner very good fuel economy ratings of 9.0 city and 6.8 highway.

The 2.0-litre, four-cylinder diesel engine in the TDI delivers the least power, 140 hp at 4,000 rpm, but the most torque, 236 lb-ft, all of which is available from 1,750 to 2,500 rpm. Its fuel economy ratings are 6.8 city and 4.9 highway. The on-board readout was showing an average of 7.1 L/100 km when I returned it.

The "oil burner" appellation used above is in reference to the bad old days of low-powered and stinky diesel engines. This new one makes 40 hp more than the previous 1.9-litre unit and burns ultra-low-sulphur diesel very efficiently and cleanly and is also quieter.

And the direct shift gearbox (DSG) is a treat, snapping off lightning-quick shifts automatically or allowing you to select gears yourself. Although it takes a while to get used to the fact that it only revs to about 4,500 rpm between the gears, acceleration is surprisingly strong.

And its direct steering, firm suspension and good brakes also contribute to making it a very enjoyable car to drive.

The Jetta TDI is available in base manual transmission Trendline form at $24,275, in Comfortline trim at $26,775 and Highline versions go for $29,775. Our DSG-transmission-equipped tester had a sticker price of $31,175 and an all-in-but-the-taxes cost of $33,510. By comparison, a base gasoline Jetta 2.5 goes for $21,975 and a base 2.0 TSI for $27,475.

The base TDI comes with the usual features at this price, plus cruise control, climate control, 16-inch wheels, exterior temp gauge, a single CD audio system and front, side and side-curtain airbag systems.

The Comfortline has some extra chrome trim, a power-reclining driver's seat, heated seats, leather-wrapped wheel and a premium six-disc audio system. The Highline adds a compass, leather upholstery, a multi-function wheel, a sunroof and a rear armrest/pass-through.
In typical VW fashion, the interior is designed to meet more utilitarian than utopian standards for style. There's rather-uninspired plastic aplenty, not only where you can see it but also feel it — the surprisingly nasty and hard-edged door pull, for example.

The somewhat stark look and feel is ameliorated by stitched padding on the armrests, rather-nice mesh-finish aluminum trim and thin aluminum bezels around the gauges that perk up the plainness a bit.

The cabin is quiet enough at highway speeds, the leather-clad front seats are supportive and comfortable, the rear seat will handle two in comfort, headroom is good front and rear and the trunk capacity is fine at 400 litres.

In fact, if I had to cover a lot of mileage on an annual basis, I'd be happy to do it in the TDI, and would likely save some money if I kept doing it long enough. But the potent 2.0 TSI turbo's fuel economy numbers are pretty good, too, and it would still be my choice among the Jetta triad.

2010 Ford Mustang GT Road Test

A Mustang with a Track pack?

Corvettes and Vipers grab the glory for Old Glory at temples of speed such as Le Mans. The lumbering, log-axle Mustang is just a quarter-miler for the tattoo-and-tobacco crowd, right?

Actually, mes amis, the Mustang is America’s other road-racing workhorse. It has its own pro series, the eight-race Mustang Challenge. And there were more than a dozen Mustangs on the grid at Daytona this past January when a Roush-prepared Mustang finished second in the three-hour Koni Challenge race. It made all its rights and lefts better than Porsche 911s and BMW M3s.

No, we wouldn’t expect that hierarchy to hold on the street, even if the 2010 Track-pack Mustang GT is billed as the hairpin-and-carousel king of the newly reskinned Mustang lineup. Still, Ford’s old pony has a long history of making incremental improvements as it ages, and the Track package shows that the late-night lights still burn in some windows at Ford.

Building a Track-pack Mustang on the order form starts with a GT Premium and its 315-hp, 4.6-liter V-8 and five-speed manual, for $31,845. The $1495 Track package swaps out the 3.31 or 3.55 axle for a 3.73 limited-slip rear end with carbon friction plates. The shocks are less forgiving in both compression and rebound, the anti-roll bars are thicker, and dual-piston front brake calipers with performance pads from the 2009 Bullitt model do the stopping. Also, the stability-control system is retuned to tolerate more sideways play.

Finally, some very expensive Pirelli P Zero summer tires are fitted with white gloves. The size is 255/40ZR-19. The replacement price at Tire Rack: $398. Each. Avoid parking in dark alleys.
Off to the track we marched, taking along a standard Mustang GT rolling on its Pirelli P Zero Nero all-season tires for comparison. The results were illuminating.

Besides new sheetmetal, all 2010 Mustangs are recalibrated for less squish, less wiggle, less pogo, and less teeter-totter in the turns. Lay on the Track-pack version, and the strings are pulled even tauter.

The body isn’t allowed to slump to the outside as much. Helm response quickens, and corner placement gets finer. The sticky Pirellis earn their tariff, maintaining a gummy, squeal-free grip that keeps the front end carving smooth arcs.











Mustang steering has always been numb, and the Track pack doesn’t force any more circulation into it. Don’t bring along a Miata, as we did, or you’ll just get depressed. The Mustang’s flat seats allow you to flop around—we had knee bruises at day’s end—and the brake pedal started melting after a few laps, requiring frequent cool-downs.

At $33,340 before discounts, a Mustang GT with the Track package stampedes into territory prowled by the Nissan 370Z, among others. Some would say, “So what?” More is at issue than test numbers cavorting on paper. The Mustang is America, Manifest Destiny rolling on radials. Lining it up next to a Z—we did it once, back in 2002—is like serving sashimi with succotash.

And the Mustang is as fun as firecrackers on the Fourth. Everything is oversized and executed at volume 11, from the broad sweep of the double-hump dash to the big-grab shifter to the Yankee roar of the V-8 getting to 60 mph in 5.1 seconds.

It’s easy to be fast and pitch it sideways in a drift. And a sport mode in the new-for-2010 stability control allows a little more hooliganism within the safety net.

The quality is better for 2010, especially inside, where stitched panels on the doors and tighter-fitting, squishable plastics have relieved the gloom of cheapness in the previous model. But curses were muttered when the jagged splinter of an indifferently applied spot weld in the trunk tore an expensive down comforter. A Friday build, perhaps?

Though freeway ride suffers some with the Track package, Mustang fans who prefer candy-cane curbs to Christmas trees get a lot more control of their fillies. And for not much extra cabbage.

2010 Chevrolet Camaro SS Road Test

The arrival of the Chevy Camaro finally completes Detroit’s pony-car trifecta. Does the Reborn Ponycar Live Up to Its Name?

Since the last pill-shaped F-body Camaro rolled off the line in 2002, the long-fought, often contentious pony-car game has been one of solitaire, played solely by the Ford Mustang.

The Mustang went all retro in 2005, and the ensuing craze prompted Dodge and Chevy to rouse their own dormant nameplates (and fans) to take on the foe-less leader. Dodge was first in 2008 with its resurrected Challenger, and now—just as Ford is launching its significantly updated 2010 Mustang—Chevrolet has finally commenced production of its reborn Camaro, completing the new-age pony-car trifecta.

While we will save the official comparison test for later, we can aver that the neo Camaro offers the freshest and most modern package of the three. Built as it is on GM’s superb Zeta full-size platform, it sports a fully independent suspension, along with evocative, contemporary styling that thankfully misses being totally retro.

We entered into this first test of the long-awaited 2010 Camaro with high expectations. Indeed, with a 304-hp, 3.6-liter V-6, the base Camaro is nearly as powerful as the Mustang GT, and so we were champing at the bit to see what the Camaro could do in SS form, with a 6.2-liter V-8 stuffed under its hood.

How Quick Is It?

With the six-speed automatic, the Camaro SS can hit 60 mph in a scant 4.6 seconds, with the quarter-mile arriving in 13.1 at 109 mph. At 4.8 seconds, the Camaro with the six-speed manual takes 0.2 second longer to hit 60, but overtakes the automatic by the quarter-mile mark, clocking 13 seconds flat at 111 mph. (The L99 V-8 hooked to the automatic is rated for 400 hp and 410 lb-ft of torque, while the LS3/manual combo is good for 426 hp and 420 lb-ft.)

For comparison, both the 315-hp 2010 Ford Mustang GT and the 376-hp, 5.7-liter Hemi-powered Dodge Challenger R/T do the trick in 5.1 seconds. The better-matched but pricier Challenger SRT8—with a 425-horse, 6.1-liter Hemi—hits 60 in 4.8 seconds. So until Ford gets the Mustang GT into the gym and stuffs more power under its hood, Chevy has earned bragging rights in the segment where burliness arguably counts the most.

On a drive that took us along the scenic roads east of San Diego, California, we also found the Camaro’s roadholding to be quite stellar—it grips with 0.92 g on a skidpad—thanks in part to the independent multilink suspension out back and the stickiness of the fat, Z-rated 245/45 front and 275/40 rear tires mounted on 20-inch wheels. The variable-ratio steering rack delivers great on-center feel, similar to that which we’ve praised on the Camaro’s platform-mate, the Pontiac G8.












Quiet + Calm Ride = Surprising Comfort

The Camaro SS packs a few surprises, however. The engine is remarkably—and to some, disappointingly—quiet, at least from inside the cabin (based on the shell-shocked looks on the faces of people we blew by, it appears that it’s plenty loud on the outside).

For high-speed cruising, this is a good thing, as there is no shred of that exhausting boominess that can add misery to long-haul muscle-car motoring. But at the same time, we found ourselves wanting a bit more of an audible reminder that we were driving something with 426 freakin’ horses under the hood. Even at full tilt, the engine didn’t seem to have the trumpet-like blat of the Challenger R/T’s 5.7-liter, let alone the NASCAR-worthy howl of the 6.1-liter in the SRT8.

Another surprise is the eerily serene ride, which makes the quietness seem even quieter. Particularly at freeway speeds, the Camaro’s Zeta roots pay dividends, striking a brilliant balance between lively, grippy roadholding and wonderfully compliant damping. Meanwhile, the SS offers decent feedback through the steering wheel. A guy could cruise all day in this thing and never feel beat up.


















Drives Big

At higher speeds, however, is where one misses things like outward vision. The very low roof, high waistline, and wall-like rear pillars make the car drive big (not good for twisty two-laners), although the Challenger drives bigger yet.

Lane-changing is a point-and-squirt affair rather than anything involving an over-the-shoulder check. The exterior mirrors help, with the bonus that they give you a close-up view of the Camaro’s sexy hips. The interior mirror is utterly useless; all one sees when glancing rearward is an ocean of black roof and C-pillars the width of a Sequoia (the tree or the Toyota).

Also disappointing are the hard plastics that we had hoped were banished from GM interiors, but they’ve clearly found their way inside the Camaro.

Furthermore, the inset dashboard trim piece that was to be rendered—at least optionally—in a cool illuminated band of light-tube trickery has now become a cloth insert. And finally, as great as the high-mounted squircle-shaped gauges and cool center stack look, the script is tiny and the buttons can be ergonomically challenging in operation.
But the Camaro is beguiling.

It has a strong design, a strong heritage, and delivers seriously strong acceleration. It will do well with its established fan base, and should even earn a few more admirers in its new life.

And not insignificantly, the EPA just gave it excellent fuel-economy ratings. Could it be better? Absolutely, but at least its deficiencies involve its interior detailing more than its dynamics. Besides, in these tumultuous, unpredictable times, we should celebrate the mere fact that pony cars like this are here at all.

Welcome to the herd, little pony.

2010 BMW Z4 Road Test

Road Test: 2010 BMW Z4, which officially revealed at the 2009 North America Internationl Auto Show at Detroit. See details after the jump.

Two market segments in particular have been decimated by the Great Recession.

First, the Bentley-Ferrari-Porsche 911 area has effectively been castrated in the past six months.

Second, there are the smaller two-seater premium Euro roadsters we all love so well in the best of times: Porsche Boxster, Mercedes SLK, Audi TT Roadster, and BMW Z4. For these little guys, emasculation similes do not suffice.

BMW has slightly merciful timing on this new Z4. The last-generation coupe and roadster stopped production in Spartanburg right as the collapse was preparing to crush us all in July 2008. Now the new generation Z4 is cranking up in Regensburg, Germany, for a May 9th worldwide launch of deliveries just as a few signs are popping up that the start of the long bottoming-out could be upon us, bolstering at least a little confidence.

And we can all say bye-bye to the costly soft top and fixed top versions approach, since Munich decided a while ago that a folding hardtop covers all needs in this minor profit center segment. For this quickie drive review prior to the full story in next month’s Winding Road, we’ll focus on the key driving points and personality of the third-generation Z4 -- called the E89 internally by BMW.

Seeing the previous two Z4 roadsters sitting beside this new one pretty much tells the full story on how the car has altered its persona. In a modern way, the profile of the new Z4 is as beautiful to our eyes as that of the classic 507 or short-lived Z8.

The proportions are classic rakish Euro roadster with a clamshell-opening aluminum hood that is 5.5 inches longer than that on the last-gen Z4s. To the eye, this positions the two occupants much more to the rear axle though the wheelbase remains the same.

Then, given the packaging needs of the two-piece aluminum folding top, the shape of the rear end is raised a bit and it’s this line that ties it so closely to those classic proportions.

Then the front and rear ends are wider with light elements that emphasize this added width, a visual trick that is all the rage these days at every German builder. Thus, stared at from above, the footprint of the latest Z4 is basically rectangular as on most of the roadster bodies we lust after.

Inside, the form language carries over and everything is a little more generous and elegant than on the previous cars. Cockpit shoulder room is up almost an inch, elbow room by almost two inches, and these touches resolve one of the Z4’s old troubles: we felt hemmed in before and so the Z4 was never the choice for a longer distance drive.

This one stretches out a bit and matures up, thus attracting a different, possibly older, customer with more cash to play with. (The sDrive30i starts at $46,575 pre-tax with standard six-speed manual, the sDrive35i at $52,475.)

The only testers available in our Spanish try-out were top-of-the-line sDrive35i models with the new seven-speed dual-clutch Sport Auto transmission, though we did manage a quick try in a manually equipped 35i for you.

Both are terrific to be sure, but with the seven-speed we are miffed by the automated upshifts close to the 7000-rpm redline even in the Sport+ mode of the Drive Dynamic Control and kickdowns whenever we jam on it for overtaking.

This is a safety choice by BMW and it states clearly that this Z4 even at the top end is now meant for average drivers. Still, if you don’t mind anticipating the ECU police by 100 rpm or so, the shifting is swell and the exhaust sound is burly without being brash.

Playing with the new DDC -- normal, sport, sport+ -- also modifies the suspension and steering and the differences are more subtle than any previous mode system, but Sport+ is our overall choice especially if we find ourselves on these sensational roads above the Andalusian coast.

Our other favorite mode is roof down. The two-piece hardtop weighs 66 pounds more than the old ragtop, takes twenty seconds to open or close, and thankfully looks really good either open or shut.
