Mercedes Benz E450 Review

Introduction
Mercedes has introduced the E450 variant of the V214 E-Class sedan for chauffer-driven owners who occasionally enjoy driving as well. It’s a good balance between luxury and performance. Powering the E450 is a 3.0-litre, inline 6-cylinder turbo-petrol M256 engine that makes 375 BHP and 500 Nm torque. It’s mated to a 9-speed torque converter automatic transmission that sends power to all four wheels and it can do the 0-100 km/h sprint in 4.5 seconds. It’s priced at Rs. 92.50 lakh (ex-showroom) and is available in the AMG Line trim. We got to spend some time with the car, so let’s get into the details.
Since the Mercedes E-Class has already been reviewed by Team-BHP, this report will only focus on differences in the E450. To read the full official review,

At the front, the big differentiating factor is the AMG Line bumper:
The same goes for the rear. Nothing different apart from the rear bumper:
On the sides, you get a different set of wheels:
AMG Line bumper looks more aggressive than the E200 and also gets air curtains to direct the airflow towards the wheels. Also note that you get projector LED Digital lights instead of reflectors:
The front brake discs are larger in size compared to the E200 and the E220d:
AMG Line 18-inch alloy wheels look okay, but nothing special. The regular set of alloys on the E200 looks better IMO. The wheels are shod with 225/55 R18 Nexen N’Fera Sport tyres:
Chrome treatment on the rear bumper feels unnecessary:
Dual exhaust tips are fake. You get twin exhausts that are tucked under the bumper:

Interior design is almost identical to the lower variants:
Given that this is the AMG Line trim, Mercedes should’ve provided the AMG steering wheel:
While the E200 & E220d get the open pore black wood-like finish on the center console, the E450 gets piano black:
Rear seats set a benchmark in this segment for comfort:
Driving the Mercedes E450 3.0L Turbo Petrol AT
3.0-litre, inline 6-cylinder engine puts out 375 BHP @ 5,800-6,100 rpm and 500 Nm @ 1,800-5,000 rpm. It is mated to a 9-speed torque converter AT:
The previous generation was available with a V6 internationally which was essentially a V8 with 2 cylinders chopped off. In this generation of the E-Class, Mercedes has brought back the inline 6-cylinder engine. This M256 engine is an extended inline 4-cylinder engine (M254) that we saw in the E200. It’s basically the same engine with 2 extra cylinders. They share the same cubic capacity per cylinder (500 cc) and also have the same bore & stroke. In fact, we drove this engine last year in the GLE 53 AMG, but it was in a higher state of tune (429 BHP and 560 Nm). The M256 engine gets a 48V onboard electrical system with an integrated starter alternator which provides additional power and torque at low speeds and low rpms. It is mated to a 9-speed AMG Speedshift TCT 9G torque converter AT.
Fire up the engine and there’s no AMG-like drama. The engine purrs silently at idle. You can just slot it into D and drive off. The throttle response is good, but you might feel that it’s a bit too sharp at low speeds. Once you get used to it, you can modulate it easily. The highlight of this engine, when we drove it in the GLE 53 AMG, was its smoothness. Even in the E450, despite all the power and torque available, the engine is smooth and you don’t feel any spike in power delivery. Driving around in Comfort mode in the city, the E-Class feels at home. The gearbox goes through the gears without letting you know. There’s enough power on tap to just roll comfortably and make those quick overtakes if needed. Once you get used to the dimensions of the car, you won’t have any trouble manoeuvring the E-Class even on the busiest streets with ease.
But this engine is all about performance. So, once on the highway, you can really get to experience its potential. Thanks to the integrated starter alternator (ISG), the engine has good power at the low end which means the turbo feels very seamless. You will get up to highway speeds very quickly. Cruising is a comfortable affair and overtakes on the highway are also done with ease. The engine never feels strained and just keeps delivering more power. Given the 6 cylinders and the 4MATIC all-wheel drive tech, I had to try out some acceleration runs and the E450 didn’t disappoint. The car's claimed 0-100 km/h time is 4.5 seconds which is very much believable. The all-wheel drive offers excellent grip during launch and prevents any wheel spin. There’s so much torque and power that keeps the car pulling strongly until you get off the throttle.
The 9-speed torque converter automatic is fairly quick. This is not an AMG performance version, so you don’t need aggressive shifts like the 7-speed dual clutch. You can barely feel the shifts while driving around. It also always seems to find the right gear and is never confused. There’s also a manual mode that can be activated from the touchscreen which allows you to take full control of the shifts. All in all, the 9-speed torque converter gearbox suits the engine and the character of the E-Class very well.
The E450 has a total of 4 drive modes: Eco, Comfort, Sport and Individual. These modes alter the throttle and steering response:
In
Eco mode, the throttle response is dull and the gearbox upshifts earlier to maximise fuel efficiency. This mode provides the smoothest ride and honestly, with the power and torque that the engine produces, it is good enough to be used in the city as well as on the highway.
The
Comfort mode is the default mode which is in between the Eco and Sport modes. It works well in town and on the highway and offers a good balance between efficiency and performance.
In
Sport mode, the engine becomes more responsive and eager to react to throttle inputs. The transmission holds a gear for a longer time and the steering firms up too. Unlike most other cars, the Sport mode in the E450 is not very aggressive. The engine’s inherent smoothness means that the power delivery does not feel very spiky even in the city.
Individual mode gives you the option to customise your driving experience to your requirements.
Noise, Vibration & Harshness (NVH)
You can barely hear the engine in the cabin at idle and while driving around in the city. The engine note at high revs is nice and sounds sporty. It’s not too loud nor is it forcibly muted and the engine doesn’t sound strained. It’s not the usual AMG-loud with pops and bangs, but a note that most people will enjoy.
Wind noise and road noise are well controlled at 100-120 km/h.
The bonnet gets insulation and the a heat shield on the right. This is because the exhaust manifold, turbocharger and catalytic converter, which are all hot components, are placed on the right side of the engine:
Suspension
Ride Comfort
When we drove the E200, the ride comfort was very good, especially for Indian road conditions. We are glad to report that the E450 retains the comfortable suspension. At slow speeds, the suspension feels absorbent and small bumps and potholes are soaked up well. You do have to be mindful of the fact that it’s a German sedan, but other than that, you won’t find any issues with the suspension at slow speeds. However, you hear the bumps or potholes inside the cabin if taken at speed. As the speed increases, the ride gets flatter. There is a bit of vertical movement over road undulations, but it’s not excessive.
Handling & Dynamics
Straight-line stability is good and you or the passengers won’t realise that you are cruising at triple-digit speeds. The car masks speed quite nicely. The downside of this comfort-oriented setup is that you’re not really encouraged to attack corners. The all-wheel drive setup provides that extra grip in corners, but you do feel some body roll. The E450 rides on the same 225/55 R18 Nexen N'Fera Sport tyres as the E200 and they provide decent grip. The important thing to remember is that this is not an out-and-out performance version of the E-Class. This is a luxury sedan with a more powerful engine. So it focuses on a comfortable ride quality. While the E200 is primarily for chauffeur-driven customers, the E450 is for people who occasionally like to get behind the wheel.
Steering
The E-Class has a very light steering that is easy to use in the city and on highways. It is fairly direct which makes the car very easy to drive. Manoeuvring this long car through the city and even taking 3-point turns doesn’t feel very cumbersome due to the user-friendly nature of the steering. It weighs up a fair amount on the highway and makes cruising quite comfortable. From an enthusiast's point of view, however, it is still light (even in Sport mode) and although direct, it doesn’t feel very confidence-inspiring in corners.
Braking
Given that the E450 is heavier due to the engine and all-wheel drive setup, the front brake discs are larger in size than the E200 or E220d. When you are driving within the limits, the brakes work perfectly and more importantly they are very predictable. Under hard braking, the car stops without much drama. The E-Class is also equipped with Active Brake Assist.
