Bigger, longer, wider, and ‘more’ in nearly every way, the 6 trades its formerly modest dimensions for a significantly stretched skin. Similar to these check this out  But by dropping the popular wagon and hatchback models, is a ‘one-size-fits-all’ the best way to go? Time will tell.

Ah, power. It corrupts absolutely, right? Well, not in the case of this car. Usually in front-wheel-drive cars, more than 260 horsepower is too much to handle. Check this out . Not here. And really, who doesn’t like driving a sleeper “wagon” that will do 240 km/h without breaking a sweat?

We see a 3 Wagon. And apparently there’s nothing sporty about wagons. But naming this hatchback ‘Sport’ has helped it find favour with many drivers around the world, and really, the more wagons the better. Great practicality mixed with unbeatable driving pleasure.

Porsche Boxster

The entry-level Porsche is proof positive that automotive exhilaration is possible without explosive acceleration.

The Boxster is decently quick (0-100 km/h in 6.6 seconds), but no more than that. The real joy in driving this mid-engined 2-seater comes from its way of doing things rather than what it does: the blood-curdling wail of the exhaust note at 5,000-plus rpm; the near-perfect blend of steering feel and effort; the way you can explore its handling limits without fear that it will turn around and bite you.  Used low km Toyota Nissan . Essentially unchanged for ’99, the Boxster is propelled by a 201-hp, 2.5-litre Boxer six mounted behind the (two) seats. A 5-speed Tiptronic automatic, which permits sequential manual shifting, is optional to the standard 5-speed stick. The soft-top is power operated, an aluminum hardtop is optional.

Mercedes-Benz SLK

The SLK is famous for its roof – the automatic retractable hardtop transforms it from coupe to roadster in 30 seconds. While the SLK is a two-seat open-air automobile, it’s not a performance or handling maniac like some of its roadster competitors. But SLK moves in that direction for 1999 with the new availability of five-speed manual transmission and optional AMG-designed Sport Package.

In addition to cosmetic enhancements (side sills, and new front and rear facias), the Sport Package adds handling muscle via a bigger version of its staggered wheel and tire set up (225/45ZR17 front, 245/40ZR17 rear). Motivation remains the duty of supercharged 2.3-litre “four” which cranks out 185 hp, and 200 lb. ft. of torque anywhere between 2,500 and 4,800 rpm. Also carried over is the driver-adaptive 5-speed automatic.

Ferrari 550 Maranello

The 550 Maranello is your basic front-engine, rear-drive, two-seat sports coupe -NOT! While the formula and styling seem traditional and North End Garden City Maples Used Truck Dealership, there’s lots about this Ferrari that’s over-the-top and/or futurama. Like the 456M 2+2 it’s based on, the Maranello has an aluminum body welded to an alloy steel frame.

The long front hood harbours an even more potent rendition (485 hp at 7,000 rpm, 419 lb.ft at 5,000 rpm) of the 5.5-litre, 48-valve, V12. The 6-speed manual is mounted as a unit with the final drive in the rear. There’s traction control so things don’t get out of hand, but no, Sheldon, you can’t have an automatic.

With the exception of the baulky shifter, this Ferrari is as user-friendly as a Corolla. But unlike the Toyota, this thing’s geared for 320 km/h and can get there in an awfully big hurry.

Test the exhaust emissions

The vehicle may also be connected to an exhaust-gas-analyzer by inserting a probe into the tailpipe. With the car running in Neutral, the mechanic can check the amount of carbon monoxide (CO) and hydrocarbons (HC) in the exhaust (other emissions can be tested with more sophisticated analyzers, but these two reveal a great deal). He will check the engine at idle and at higher rpm, comparing the results to specs for that specific make and model of vehicle. A good test means that the engine’s carburetion/fuel injection is working efficiently. Engine mechanical problems such as worn rings, valves, and valve guides can also be detected through an emissions test.

Tip:

In some states, an emissions check will be required before you can register the vehicle in your name. If not provided by the seller, it may be wise to get the required state certification at this time.

More Clout for Calibra

Sleek, attractive, and well finished, the Opel Calibra coupe came out of the box a pretty strong offering for the GM Europe team. Its 150-horsepower 2-liter 16-valve twin-cam four gave the top-line model an 8.2-second 0-60-mph capability and a top end of 138 mph. But the playing field changes quickly in the sport coupe game, and with Volkswagen fitting its new Corrado with a 178-horsepower 2.7-liter V-6 and Ford launching the 227-horsepower Escort RS Cosworth, GM felt it was time to give the Calibra a stout under-hood upgrade. Enter the Calibra Turbo. With the addition of a force-feeding system, engine output jumps to 204 horses and torque to 207 pound-feet. Matched with a new Getrag six-speed gearbox, it’s sufficient to propel the Calibra-in either front- or all-wheel-drive configuration-0-60 mph in under 6.5 seconds and push it to speeds in excess of 150 mph. Torque is so plentiful that sixth gear is useable from as low as 2000 rpm. Comfortable, quiet, and competitively priced, the Calibra Turbo is destined to be one highly sought player.

Where Does All the Horsepower Go?

When a car manufacturer  advertises that a V-8 engine delivers 250 horsepower, what does this mean? Technically, the term horsepower means the capability for doing so much work in so much time. One horsepower is defined as 33,000 foot-pounds of work per minute. So, the power necessary to lift 33,000 pounds one foot in one minute is equivalent to one horsepower. Suppose you weigh 200 pounds fully clothed. If you were to climb a stairway 10 feet high in slightly over 3 1/2 seconds, you would be developing about one horsepower.

Advertised horsepower, the figure you find in brochures and tabulations of data, is measured at the maximum power output point on a curve of horsepower vs. engine rpm. Normally, power output increases with engine speed up to a maximum. At higher speeds, the friction and flow losses cause power output to fall off. However, a car that advertises 250 horsepower may deliver only about half of that power to the rear wheels. Where does the rest of the power go? When rated for output, an engine is stripped. Accessories and power train elements subtract from this maximum power until, by the time the power reaches the driving wheels, half of the available engine power has been drained away. Some of the power-robbing elements include:

  • Dual mufflers reduce power output by roughly 7 per cent at high speed – single mufflers  by roughly 14 to 15 per cent.
  • Air cleaner subtracts another 3 per cent at high speed. Muffler and air cleaner losses are proportionately less at low speeds.
  • Heat-riser valve to speed warm up it takes its bit out of the horsepower pool to the tune of 2 to 5 per cent.
