Premium generic and hybrid attributes l.jpg
Premium Generic and Hybrid Attributes delivering a significant CO

  • When applying hybrid technologies to established, premium vehicle lines, two sets of vehicle attributes need to be considered

    • Generic vehicle attributes, e.g. vehicle acceleration, load-space capacity etc.

    • New hybrid vehicle attributes, e.g. EV range, charging requirements etc.

  • In order to design a credible hybridised proposition it is necessary to balance hybrid attributes with generic vehicle attributes, maintaining premium luxury.

Phev effects on premium attributes case study 1 acceleration l.jpg
PHEV Effects on Premium Attributes delivering a significant COCase study 1 - Acceleration

Unless compensated for, a PHEV system will degrade maximum vehicle acceleration via two mechanisms:

  • Weight (incremental to base vehicle)

  • Power delivery limits and delays due to engine cranking.

Crank Delay

PHEV Effects on Premium Attributes delivering a significant COCase study 1 - Acceleration

  • Additional weight can be compensated for if the HEV system can provide incremental motive power on top of the IC engine.

  • EV launch limits and engine crank delays can be compensated for by careful gear sizing, and by using electric propulsion to offset engine crank delays.

More weight needs

more power to

compensate

HEV motor fills

in the gap left by

the crank delays

Jaguar & Land Rover Hybrid Technologies


Phev effects on premium attributes case study 1 acceleration23 l.jpg
PHEV Effects on Premium Attributes delivering a significant COCase study 1 - Acceleration

If compensation is the minimum requirement, an obvious stretch target is to use the HEV system to significantly (and recognisably) improve the acceleration performance.

For example:

  • 72kW/120Nm (at the crank) electric boost on top of a 240bhp engine can make a 3 tonne vehicle accelerate like a 2 tonne equivalent.

  • 80kW/160Nm (at the crank) electric boost on top of a V6 diesel will accelerate like an equivalent V8 diesel.

  • 160kW/330Nm (at the crank) electric boost on top of a V6 diesel will accelerate like a V6 diesel with no turbo-lag whatsoever.

    Clearly some of these are easier to achieve than others, and it is up to the individual OEM to decide what acceleration performance is appropriate for their HEV vehicles, and therefore what size of hybrid system is required.

Estimated CO2 car emissions by journey purpose and journey length (GB, 2002 / 2006 average)

63% of a cars total daily journeys per day < 25 miles therefore one overnight charge is sufficient in this case.

37% of a cars total daily journeys per day >25 miles and would require the engine to start.

Sustainable limit l.jpg
Sustainable Limit delivering a significant CO

  • The ultimate transport?

    • Walking/Cycling

      cycling at 9.4mph = 23.3 kcal/km

      walking at 4mph = 40.4 kcal/km

      Food results in 1.4 tonnes CO2/person/year = 1.5 gCO2/kcal

      cycling at 9.4mph = 34 gCO2/km

      walking at 4mph = 61 gCO2/km

An interesting sanity check on possible lower limits points to a practical lower limit in the region of 40gCO2 / Km.
