Away from the show, there will be five models launched over the coming months: C200 petrol and BlueTec diesel; C250 petrol and diesel, and a C300 diesel hybrid that's engine is found in the current E-Class version.
In the NZ dealerships first will be the C200 and C250 petrol and C250 diesel, with the C200 diesel early next year and the hybrid in March.
In November, an array of C-Class wagons (or estates in Mercedes speak) join the range and by mid-2015 the C-Class line-up will be joined by the sports sedan C63, that has its public reveal at October's Paris motor show.
The C200 has a $2000 increase over the outgoing version and is priced at $71,900, with the BlueTec diesel at $73,400. The C250 petrol has an $86,900 price tag (add $1500 for the diesel version) and the C300 diesel-hybrid will cost $94,900.
Mercedes-Benz NZ general manager Ben Giffin reckons the C200 petrol will be the big seller for the company, taking 40 to 50 per cent of sales.
"It's such a fantastic package it's hard to go past - it's such a well put together car ... it is nearly as quick as the C250 previous model," he said.
What impressed Giffin most was the safety technology that is standard in the C-Class and that gives it the nickname of being the "Baby S-Class" due to the level of standard specifications and safety features.
"That's the most amazing thing - seeing the transition from the top of the range S-Class with the technology flowing down in our range making it affordable," said Giffin.
The C200 gets Collision Prevention Assist Plus (that brakes for you if you don't stop in time) and blind spot monitoring.
The C200 drive comes in different performance modes - comfort, eco, sport and sport plus.
There was a smooth driving quality and time to have a play with the different driving "modes": comfort, eco, sport and sport plus, as well as individual.
While eco is suited for city driving, comfort explains itself and individual allows you pick you requirement, sport and sport plus are ideal for driving at speed with my pick for winding, 100km-plus driving is the sport plus selection.
It makes the suspension firmer, cancels eco start-start and lets the engine become extra responsive.
This came to the fore when I swapped out of the C200 into the C250 with the Airmatic suspension system aligned with it.
The C200 drive was accomplished but with Airmatic the ride was smooth and the extra performance from the C250 engine it was my pick of the lineup.
But the look of the all-new C-Class line-up is impressive - a narrow boot, sculptured side panels, and avant-guard front grille gives it a sophisticated appearance.
Inside, the dash has clean lines and a simple centre stack with a new touchpad that was easy to use once it was explained to me: swipe for next track on Bluetooth soundtrack; pinch to zoom and write on the top destination.
There were a few niggles in the interior for me: The driver's foot well is too narrow and the rear seat is suitable only if you have average-height passengers - I tried it out on a 1.98m test subject whose head touched the panoramic sunroof.
Hmm, let's hope next week that none of the models being chauffeured in the C-Class are rocking beehive hair dos.
