Cor,
I have a Mitsubishi i-MiEV and it has 3 drive options D, ECO, and B.
I have driven it in all positions and varied my driving speeds and styles. from
what I could tell I got no more range in any position if I watched how I drove
i could get the same range. The tendency in D or B is to accelerate harder and
then one does get less range but if you take it easy it's about the same. B
mode definitely brakes harder and will actually bring the vehicle to a stop. I
haven't delved further into this but suspect it's a function of the permanent
magnet motor. I suspect due to eddy current losses. Does the Leaf have a
permanent magnet motor and what are your observations on the Leaf for range
differences?

OK, so Nissan spends a lot of hoopla to say that BMW is right?
And BMW is not even the first, they just made it more popular.
Many other EVs have experimented with increased regen braking selection.
My 1994 US Electricar has the option by switching its "gear stick"
to a different "gear" to choose between light regen [D], forceful regen [2]
and crushing regen [1]. I usually drive the truck in [2] which does exactly
what I hear that the new Nissan Leaf is now bringing to the masses:
1-pedal driving for everything except the moments you did not anticipate.
It feels pretty natural t hover the pedal to coast and release the pedal to
decelerate.
Cor.

Why Future Cars Will Only Have One Pedal

e-Pedal tech
]
How innovative technology will change the way we drive forever.
When the new Nissan LEAF first hit the roads back in 2010, it took electric
vehicles from a niche interest into a mainstream reality, going on to become
the world’s best-selling EV.
Owners have found it to be a great all-rounder. Its green credentials may have
been why people bought the car initially, but it’s clear from surveys that what
surprised so many was the performance, especially the rapid acceleration and
fantastic handling, which went to make it such a fun car to drive.
Its latest incarnation, due to launch in Europe in January 2018, is set to
revolutionise our automotive landscape once again. Where the original LEAF
radically altered our assumptions about the kind of car we drive, this new
version will transform the way in which we drive.
Why? Because when you’re driving you’ll no longer be moving your right foot
from accelerator to brake and back again. Instead, thanks to the e-Pedal, your
foot will stay planted in exactly the same spot to execute both actions.
New Nissan LEAF with e-Pedal technology
How does the e-Pedal work?
Francesco Giacalone, Nissan Europe’s electric vehicle product Marketing
director, knows this radical new technology intimately, and he explains how it
works.
“It’s extremely simple really,” he says. “With a normal car, to slow down you
need to move from accelerator to brake, then back to the accelerator to speed
up again. With the e-Pedal you push down on the pedal to accelerate and ease
off to brake. You can even bring the car to a complete stop by removing your
foot sharply.”
The new Nissan LEAF does still come with a brake pedal, of course, although
this is only used when the driver wants to brake more aggressively or come to
an emergency stop. The e-Pedal is activated by a switch on the central
dashboard, and the chances are you’ll keep it in this mode for most of your
driving.
What are the advantages of the e-Pedal?
“One of the biggest advantages of the new e-Pedal is it improves the efficiency
of the LEAF’s regenerative technology,” says Francesco. “With a fully electric
powertrain you can exploit both brake and regenerative energy in the smoothest
possible way.”
Regenerative technology is where, under braking or deceleration, energy created
by the car’s movement is ‘recycled’ and sent back to recharge the battery.
Regenerative braking has been around for a long time, and in the previous LEAF
the B Mode further enhanced the car’s regenerative capacities.
“The e-Pedal is an evolution of the B Mode,” says Francesco. “When you lift
your foot off the accelerator, the car is already in braking mode, so it
automatically maximises the regeneration through braking. Previously, you would
be switching back and forth between accelerator and brake pedal and would lose
some regenerative capacity that way. Now you exploit 100 percent of it.”
Getting used to the e-Pedal
What about getting used to using the e-Pedal? Given we’re so familiar with
using two pedals (in an automatic) or three pedals (in a manual), won’t our
feet be fumbling around in the foot well after a pedal we no longer need?
“The feedback we get from testing is that once you’ve driven for about 15
minutes with this system, you’re all set,” says Francesco. “After that point it
becomes the way you want to drive. For me it’s like going from using an old
smartphone with the full keyboard to a smartphone with a totally digital
touchscreen. Once you try the touchscreen, you won’t want to go back to the
older technology.”
New Nissan LEAF
What change will the e-Pedal make to everyday driving?
The e-Pedal is particularly useful in stop-start traffic says Francesco. “In
commuting you might drive for 100 meters then brake, then drive for 20 meters
then brake and so on – this shifting back and forth between accelerator and
brake is happening a lot.
“In tests Nissan undertook with nearly a thousand drivers using the e-Pedal on
their everyday journeys, what we discovered is that this back and forth action
between accelerator and brake is reduced by a massive 90 percent.”
There will be major advantages to people who use cars on a professional basis,
like taxi drivers or people who use the vehicles for deliveries and so on.
“Driving this way becomes much more smooth, fluid and natural,” says Francesco.
“It makes driving much less stressful, and for anyone who’s job means they have
to spend hours driving around towns and cities, it will be a massive benefit.”
What else can we look forward to from the e-Pedal?
Electric vehicles are often criticised by petrol heads for lacking driver
involvement, but the e-Pedal will turn that assumption on its head, according
to Francesco.
“On fun, winding roads where there is little traffic, using the e-Pedal almost
feels like motorbike-style driving, making the car more sporty. When you
approach a corner you lift your foot off the accelerator to brake – the braking
uses an intelligent system that regulates the brakes and wheels – then without
removing your foot from the pedal you can start to accelerate out of the
corner. It’s a safe, fun drive that delivers excitement.”
The new Nissan LEAF’s battery pack sits low in the chassis, so this also helps
the car hug the road, while the new, sleeker design reduces drag and lift on
the car, giving it even more stickiness on the road for that sportier
experience, should you want it. So, the fun driving characteristics that so
surprised buyers of the original LEAF are not only still there, they’ve been
taken to a whole new level.
“Nissan’s commitment is to constantly innovate but to make this innovation
available to as many customers as possible,” concludes Francesco. “So the
e-Pedal, isn’t an add-on you pay extra thousands of Euros for, it’s available
at entry-level on the new Nissan LEAF, so it’s about bringing this excitement
to everyone.”
