What's Hot
No packaging compromises, seamless transition between electric and diesel power, superb interior.
What's Not
Noisy at idle, couldn???t get close to fuel economy claim
Typical Mercedes Benz class, with the promise of low, low fuel consumption and greener motoring. But is it really that thrifty?

What's Hot: No packaging compromises, seamless transition between electric and diesel power, superb interior.
What's Not: Noisy at idle, couldn’t get close to fuel economy claim.
X-FACTOR: Typical Mercedes Benz class, with the promise of low, low fuel consumption and greener motoring. But is it really that thrifty?

Vehicle Style: Medium luxury hybrid sedan

Engine/trans: 150kW/500Nm 2.1 turbo diesel 4cyl, electric motor | 7sp automatic
Fuel Economy claimed: 4.0 l/100km | tested: 6.2 l/100km



Mercedes-Benz’s C 300 Bluetec Hybrid has finally arrived in Australia, sitting at the top of the C-Class range and ready to do battle with the Lexus IS 300h, Infiniti Q50 Hybrid and BMW ActiveHybrid 3 in the medium luxury hybrid segment.

Priced at $74,900 the C 300 Hybrid sits between the $59,500 IS 300h and the $100,200 ActiveHybrid 3, while it’s specced identically to the C 250 and C 250 Bluetec.

So given it retails for $4500 more than the C 250 Bluetec - which has the same diesel powerplant and same level of equipment as the C 300 Hybrid - what do you get for the extra spend?



  • Standard equipment: Leather upholstery, powered front seats, dual-zone climate control, active cruise control, auto-dimming mirrors, rain-sensing wipers, dusk-sensing LED headlamps, front and rear parking sensors, keyless ignition.
  • Infotainment: Sat-nav, 7-inch colour display with rotary controller, Bluetooth phone and audio integration, digital radio tuner.
  • Storage: Boot capacity 408 litres with rear seats up. 40/20/40 split rear seats.

Besides an instrument cluster that houses a Hybrid-specific gauge for power flow and regenerative braking, the interior is largely identical to that of the C 250 Bluetec.

And just like every other C-Class, the C 300 Bluetec Hybrid just oozes class.

It’s perhaps the best-looking interior in its segment and has the premium feel of an S-Class.

Throw a few options at it (our tester had the optional panoramic glass sunroof, head-up display, high-end sat nav and AMG pack), and it looks even more impressive, albeit at a greater cost.

Same too with the trim.

If you want something other than piano black lacquer and brushed-alloy trim you’ll need to spec one of the many option packs.

The C 300 Hybrid however gets proper leather upholstery as standard rather than synthetic Artico 'pleather', and it comes it three colours: black, beige and grey.

The C 300 Hybrid is the only model in the C-Class range to not be available as a wagon, though happily the battery pack doesn’t eat into storage space.

That means you still get 408 litres of seats-up cargo space, as well as an uninterrupted pass-through with the 40/20/40 split rear seats folded down.



  • 150kW/500Nm 2.1 litre turbodiesel 4cyl, 20kW electric assistance motor
  • Seven-speed automatic with paddle shifters, rear-wheel drive
  • Double-wishbone front suspension, multi-link rear suspension.
  • Electric power steering.
  • Disc brakes at front and rear, regenerative braking

Start up the C 300 Hybrid, and you’re greeted with a great deal of engine-clatter at idle.

It’s particularly noticeable when the window is down, but it becomes much less coarse when in motion. Thankfully, with engine start-stop, the occasions where the engine is at idlie are few and far between.

Move away, and the electric assistance motor seamlessly cuts in to lessen the load on the C 300’s 150kW/500Nm 2.1 litre turbodiesel.

That assistance motor has only got 20kW, but provided there’s enough charge in the battery and you’re gentle enough with the throttle, the C 300 can accelerate from standstill entirely under electric power.

Exercise an almost monk-like level of restraint with the accelerator, and you can even reach 60km/h without awakening the engine. It’s mighty tough though - for you, and those driving behind you.

The EV motor can also sustain a speed of around 75km/h if the ground is perfectly level.

There's no EV-only mode though, and you'll need to have a feather touch on the throttle if you want to keep the Diesel engine from firing up.

Try as we might though, we couldn’t come close to Benz’s claim of 4.0 l/100km.

On an easy-going drive from Melbourne Airport to the Yarra Valley we netted an average fuel consumption of 6.2 l/100km.

That’s in the ball-park for a hybrid in real-world use - you'll do better in city driving - but we’ll need to drive the C 300 for longer than a day and in more mixed conditions to properly assess its consumption.

Besides fuel economy, the C 300 Hybrid drives well.

It’s fairly silent and smooth, the seven-speed auto slurs through its gears and the steering has the same non-linear rack ratio as other C-Class models, gifting it with an agile feel.



ANCAP rating: 5-Stars - this model scored 36.46 out of 37 possible points.

Safety features: The C-Class has what is probably the most extensive list of standard safety equipment in its class, with nine airbags, (dual front, front and rear side, full-length curtain and driver’s knee), ABS, EBD, ESP, a collision warning system and pedestrian-safe active bonnet.

The C 300 Hybrid adds to this with the Driver Assistance Package Plus, which comes as standard. The package includes active cruise control, lane-keep assist, a pedestrian warning system, and active blind spot monitor.



There’s actually a surprising number of hybrid options in the midsize luxury segment, with the Lexus IS 300h currently the most popular. Besides the C 300 Hybrid, here are the other contenders:



Our first drive of the C 300 Hybrid was brief, and experience has shown that the benefits - and deficits - of these kinds of new-age powertrains only become apparent after a longer time behind the wheel.

It's a bit paradoxical, but stop/start city driving generally suits the characteristics of hybrids better and delivers the better fuel savings.

Is it worthy of your hard-earned? On the basis of this run, the jury is still out on whether C 300 Hybrid has proved its mettle as a green-cloaked fuel-sipper.

We'll need to assess it over a longer test with more mixed driving.

If it can’t better the 6.2 l/100km fuel consumption we recorded at the launch, then we’d recommend you save $4.5k and stick to the surprisingly frugal C 250 Bluetec instead. Stay tuned.
