2012 Mercedes SLK350

Vehicle: 2012 Mercedes SLK350 with Distronic Plus Pkg and Premium Pkg
Price as tested: CDN$72500

Performance: “Sporty”, “light” and “compact”. Has Mercedes delivered with their 3rd attempt on their smallest roadster. We will have the answer at the end of the review.

“Better late than never” is no better word to describe Mercedes’s late to the directly fuel injected party. Folks at Stuggart is 6 years later than Ingolstadt and 4 years later than Munich neighbors when it comes to advancing this technology. Mercedes has named it CGI BlueEfficiency as their marketing buzzword for this direct injection, with or without the turbo boost, add on top of the equation.

The 2012 SLK comes in the form of both a 4-cylinder turbocharged (as in designation of “250″) which will come latter in its lifespin. The subject of our tester comes in the form of a 3.5 liter DOHC 24-valve V6, with directly fuel, variable valve timing and electronic throttle technologies. It produces 302 ponies and 273 lb/ft of torque at driver’s disposal. As with all the well-honed Mercedes 6-cylinders. It provides a sort of elegant performance with best combining with world-class smoothness, refinement and NVH, even when press it to the max. This is the elegantly elogated performance characteristics only found underneath tri-star. The throttle response is decently good, while the 7-speed maumatic provides excellent ratio. The top 6th and 7th are superb for SLK’s cruising character, while 1st and 2nd encourage proper launch of the vehicle off-the-line. The bonus to the whole equation is the paddle shifters mounted on top of the sports steering, is able to override at any given gear. That means driver is able to drop a cone whenever its merging on a fast freeway on-ramp or just plain having fun through the twisties. Despite of Mercedes designation of SLK’s L being “light”, we are solely disapointed of its hefty weight this willing motor has to carry through its wrist. 1540kg is nothing sort of heavy curb weight, even if it has a retractable hardtop, as weight penalty.

Handling: Given SLK is riding on the same underpinnings as the highly-praised C-Class silibings, it doesn’t come as a surprise this is an excellent foundation to begin with as a convertible. Mercedes has stiffed up the whole structure for SLK’s roadster purpose, especially in the form of A-pillars, an area which has to haul through when the vehicle tips over. The desired result is a roadster that is as solid as a rock when driven through railroad tracks and expansion joints. It doesn’t exhibit any kinds of cowl shakes and rattles. As it comes from Stuggart, everything else is solidly put together without feeling like wet noodle. Dynamically speaking, 3rd iteration of SLK is as satisfying as the impressive outgoing 2nd generation. Those of us who remember how unremarkable the original SLK would definitely find it a huge surprise. On our SLK350, it comes with standard Sports Package, which consists of a faster steering ratio and stiffer sports suspension. The quicker steering ratio really has given SLK driver much more confidence when pushing it through the twisties, although it still has Mercedes’s somewhat numb off-center feedback. What the sports suspension does is to create a fimer ride while encouraging driver to involve in its driving more than anything else. The level of suppleness and firmness don’t sacifice much of its controlled ride quality. The body rolls are minimal, understeer and oversteer are all well-tempted given SLK’s ESP remains Mercedes instrusive even when pushed into the limits. The level of agility and balance, by combining RWD and a well-calibrated chassis, make SLK a joy-to-drive.

Brakes: With 4-wheel discs and standard ABS, SLK stops accordingly. The stopping distance is short, while pedal feels strong and solid. Even after a couple of harsh stops, it remains fade-free. Best of all, ABS doesn’t step in unnecessarily while Brake Assist doesn’t grab driver’s right foot abruptly.

Interior: When the weather is chilly but its sunny, you can open the Magic Sky Control which is basically a large sunroof. When its all sunny and hot, you can enjoy getting sunburn by operating the retractable hardtop. In only 20 seconds, it transforms the SLK from a hardtop coupe into a proper roadster. While combining a large sunroof with a hardtop convertible is nothing new, VW EOS has come years before the current SLK. It certainly makes for a more compelling reason to shop for an SLK.

The interior design of SLK mirrors those of the “Gullwing” SLS AMG. Along with the supportive sports seats, come with a wide array of standard features right from an effective auto climate control and a flat-bottom sports steering wheel. All have been finished in a sort of class one expects from the home of Mercedes-Benz.

For a roadster, its amount of luggage space especially after the retractable hardtop completely fold down, is satisfying. Unlike so many hardtop convertibles in the market, SLK actually has an usable trunk.

Conclusion: “3rd time is a charm” is the best description of the new SLK. While the original SLK is nothing more than skin deep, the 2nd generation has improved things greatly. The latest generation actually built upon the success with its predecessor. As it got a great powertrain, handles relatively well and, most of all, without losing the hallmark comfort of what Mercedes has stood for years.

2007 Mercedes SLK280/E280 4-Matic

Short review of Mercedes SLK280/E280 4-Matic
====================================
Price as tested: CDN$60500 (SLK280) CDN$67175 (E280)

Beginning in 2007, Mercedes unveiled a new 3.0L V6 for both SLK and E-Class. This powerplant will also be available in the all-new C-Class for 2008.

The highlight of this little review is this new powertrain. With 228hp and 221 lb/ft of torque, this engine serves as a very nice gap between 2.5L and 3.5L V6. This 221 pounds feet of torque available at an useful 2700rpm is simply a delight to drive around town, while 228 horses has plenty of reserves for highway passing. Not to mention Mercedes’s nifty 7-Gronic transmission is a great partner to this powerhouse. Best of all, it got plenty of performance without sacificing Mercedes’s excellent refinement, NVH and smoothness.

While the 4-Matic is an excellent AWD system, we are lamented for the dismiss of RWD E-Class in Canadian market. Only the E320 Bluetec and E63 AMG are available with RWD. If you are not going for efficient Bluetec diesel or supersedan, AWD is the only way to go for buying an E-Class.

As for SLK, we continue to be smitten by its wonderful handling dynamics. It remains the best driving Mercedes in recent memory. Sharp, precise and sporty are what best describe the SLK. With the introduction of this 3.0L V6, it would only make SLK even more popular than ever.

Overall ratings: 4.5/5 (SLK280) 4/5 (E280)

2005 Mercedes-Benz SLK350

Vehicle: 2005 Mercedes-Benz SLK350 with Sport Package, AIRSCAFT, Bi-Xenon headlights with active curve illumination system and 7G-Tronic transmission
Price as tested: CDN$77535

Handling: New SLK’s driving dynamics is simply a delightful surprise, to say the least. Along with the wonderfully stiff chassis and a fined tuned suspension system, it has to be considered as one of the solidest convertible I have ever driven. There are absolutely no cowl shakes through the roughest pavements and railroad track. Its exceptionally well-balanced thanks to RWD 50/50 perfect balance. It shoots into every corner precisely thanks to the sports-tuned multi-link suspension. The Contential tires provide plenty of grips. The harder you pushed the SLK, the more rewarding it drives. When you are pushing the SLK hard into a corner, you quickly realize its not a typical Mercedes-Benz. It got springs firm enough for enthuisastic driving without sacificing the ride comfort soft springs provide. The outgoing car’s rough ride at low speed and floaty ride at high speed are things of the past. The steering is precise, responsive, sharp and provides tons of feedback. Its also weighty enough without losing the lighter weight during slow speed parking. The body rolls are next to non-existence. If there is one pet peeve, it has to be that typical Mercedes ESP instrusiveness. Although its less instrusive than the equivalent systems in CLK and SL, it still feels more instrusive than other system like Porsche’s PSM which has 3 levels of threshold. Mercedes needs to adapt this kind of ESP in SLK given its real sports car status.

Performance: The 3.5L 90 degrees V6 DOHC engine is simply a gem. Its smooth-revving with class-leading refinement, smoothness, flexability and trackability. In order to match SLK’s sports car status, Mercedes engineers have tuned the exhaust note with entertaining music. The rumbling sound has Teutonic’s solid character that are simply a joy to my ears. The throttle response is instant. The major contributing factor for this V6 engine’s lowly 2500 rpm @ 100 km/h is the impressive new 7G-Tronic. The gear ratios are well-spaced. This system encourages spirited driving because of the aggressively tuned ratios, however, it still won’t let you rev into redline before upshifting is a slight disappointment.

Brakes: The pedal feel also lives up to Mercedes’s usual high standard. That means exceptional pedal feel and modulation. The stopping distance is short while ABS won’t kicked in until absolutely necessary.

Interior: The interior is very logically layout. The instrumentation gauges are clear and analog. The tasteful combination of aluminum trim and plastic, its a nice breakthrough from previous SLK’s sober color theme. The sports seats are comfortable with great supports all around. Mercedes designers also realized the use of knobs for climate control and stereo system are logical instead of relying on buttons. The AIRSCRAFT is an impressive feature for SLK. Once you turned on the system, it heats your head like what heated seats to your butt. It has a desired effect for a below 10 degrees Canadian weather today. If there is one drawback, its the quality of plastic. While Mercedes has improved its plastic quality a lot over the last couple of years, it still lacks the expensive feel of what you expect in a Mercedes-Benz product.

Conclusion: The new SLK has to be the best handling Mercedes ever, and rightly so. Its sharp reflexes are great enough to please sports car buyers while its also comfortable enough to satisfy typical Mercedes loyalists. In short, a very intriguing package. The AMG version would only make this great car even better.
