Weekly Motor Fix: Mercedes-Benz C350 AMG — how the Germans do it

15 June, 2015

It’s not often I get to shoot something German and late-model, but the chance came up over the weekend of June 13–14 to shoot this Mercedes-Benz C350. A car I would normally overlook, I was pleasantly surprised that although it has a diesel power train, it produces 620Nm of torque, which is only 20Nm less than a 7000cc LS7 engine produces factory in a range of high-performance GM machines — including the Z06 Corvette.

Is that what the C350 is all about though? Not at all — the C350 was designed by Mercedes to be a BMW 3–series competitor, and this one being AMG-enhanced is the equivalent to an M-spec BMW. However, I’ve driven an M-spec turbo diesel 335D, and although comparably powerful, it was nowhere near as elegant as the C350 is, in my opinion. The C350 is all about being elegant, while having enough power to impress the gentlemen on the way to golf.

The exterior is somewhat ordinary for a German car of this time however, yet the subtle front lip, side skirts, and rear bumper are all a nice addition to guide your thoughts towards performance. The 19-inch AMG alloys solidify this notion, as the factory 17-inch items are extremely civilian in comparison. The 19-inch alloys are wrapped in 235/35R19s up front and a much larger 265/30R19 down the back. Why does the diesel AMG need such a big rear tyre you ask? Well, it has a 0–100km/h time that demands such traction.

As mentioned earlier, the factory diesel power plant produces huge amounts of torque in factory form; numbers that have you wondering why we even bother with petrol engines nowadays. The C350’s diesel engine is definitely one of the most impressive things about the car. The 3000cc north-south mounted V6 features Mercedes BlueEFFICIENCY technology and stop-start wizardry to bring fuel economy figures down to 47mpg — on a full tank it can travel up to around 1000 kilometres with ease. With 195kW and the aforementioned 620Nm of torque, the C350 does 0–100km/h in six seconds flat with seamless shifts thanks to the updated 7G-Tronic transmission.

Inside the cabin you are met with all of the essential modern-day tricks. With 10Gb of hardrive space for media, dual-zone air conditioning, and nine airbags protecting the occupants, why would you leave? The air-conditioning pump is even driven by an electric motor rather than a pulley system to further enhance the already impressive fuel economy.

The seats are extremely comfortable, as you can expect of a car of this calibre, but probably not as supportive as needed with a car as capable as this. There are three memory settings for the front seats — something found essential for the family car with shared drivers. Although the interior felt overwhelmingly plastic, there were fine touches throughout with high-quality materials to even things out.

But how did it feel on the road? If you’re looking for a weekend sports car, don’t purchase a C350. However, if you’re hunting for a vehicle that performs slightly further than the average driver can actually manage, it might just be for you. It tends to oversteer when pushed, although with the amount of torque on tap it’s not difficult to bring the rear around when required. The 19-inch alloys with the lower-profile tyres do add a sharper turn-in at the expense of ride comfort, but again, this is the AMG-enhanced model, so is to be expected. Braking was impressive — 295mm cross-drilled rotors up front are a nice addition and certainly don’t succumb to fade. Definitely a good performer.

More to the point

This Daimler SP252 is so rare, few people know it exists. It’s one of a kind. It’s the only surviving, in fact the only SP252 ever completed; the would-be successor to the SP250 Daimler Dart. It is also the last sports car to have been designed by Jaguar’s legendary founder, Sir William Lyons.
Perhaps one of the original Dart’s biggest problems was it’s somewhat-divisive looks. It certainly went well enough to win fans, although Sir William wasn’t among them. It crushed the opposition in the Bathurst six-hour race, finishing five laps ahead of anyone else, and it was snapped up by police forces in Britain, Australia, and New Zealand, as it was the fastest thing on the road.
So you’d think a stunning new body with the magic Lyons touch would have been a surefire success. Why this car never made it into production is still something of a mystery, as the official explanations barely stack up.

Polishing to perfection

The secret to a show-stopping finish is colour sanding, no matter which paint system you use. Even a good painter, no matter how experienced or talented — like my mate Bruce Haye, CEO at Ace Panel and Paint in Whitianga — can’t shoot to a perfect mirror finish. To get that level of perfection, you need to colour sand.
It used to be called ‘rubbing out’ or ‘cutting’, and it was done with pastes that came in cans. They worked — sort of — but the compounds really just rounded off imperfections instead of eliminating them, and they removed a lot of paint in the process. But now your new finish can be made flawless, thanks to microfine sandpapers that come in 1000, 1500, 2000, and even 2500 grit ranges, and Farecla G3 polish — available from automotive paint suppliers.
