To overcome the C - MAX Energi's
battery weight penalty, Ford installs a 2.0 - liter, 141 - hp gas engine that works with its 88kW electric motor for a combined 188 hp.
Not exact matches
The platform is also modular, so
battery and power outputs can be changed, while a combination of aluminium, steel and carbon fibre should mean the
weight penalty from
batteries is reduced.
That's an objectively good number, but it's difficult to say if it's worth the extra cost: when the plug - in
battery is depleted and the Energi runs in hybrid mode, it averages 4 fewer mpg than the Hybrid, due to its 259 - pound
weight penalty.
Infiniti says the
weight penalty for the hybrid system is 265 lb, which sounds quite optimistic given the enormous
battery.
With a bigger
battery comes a larger
weight penalty as well — the S500's pack weighs around 286 pounds, while the S400's
battery tips the scales at 165 pounds.
One point worth considering is that, with the C300h in AMG Line trim, you suffer a 120 kg
weight penalty thanks to the electric motor and its lithium - ion
battery pack.
Not only is the transition from pure - electric to petrol power smoother, the 2.0 - litre comes with a significant
weight - saving over the old V6, helping offset the added 150 kg
penalty of the 13.1 kWh lithium - ion
battery that lives in the rear wheel well.
Porsche insiders admit the 150 kg
weight penalty of an electric motor and
batteries would substantially take away from the spirited driving experience we've come to expect from a Porsche.
There is very little
penalty in
weight or performance thanks to a lack of
batteries: the electrical energy is provided by a generator which is hooked up to the engine.
Clever stuff, theoretically with no unsprung
weight penalty, although
batteries are still the great unknown.
