Lexus is taking the “green car” experience to another with the presence of its LS600hL at the 2008 Johannesburg International Motor Show (JIMS).
It is one of the “ultimate” environmentally-friendly luxury cars, and Lexus says it is under serious investigation for imminent introduction to the South African market.
The key characteristic of the LS 600h L is the hybrid drivetain.
A 5-litre petrol V8 engine is augmented by two electric motors supplemented in turn by a large capacity battery pack.
This combination powers up to 326 kW of peak power, enough to blast the LS 600h L from 0-100 km/h in under six seconds via a dual-stage electronically controlled continuously variable transmission.
Transmitting power to the road is an all-wheel drive (AWD) system changing through a new transfer case that is ultra quiet, compact and equipped with a unique Torsen limited-slip differential (LSD) that is 30 percent lighter in size and weight than previous Torsen systems.
To maximize the AWD system's performance, the LSD features a rear biased torque distribution of 40:60 under normal straight-line driving.
The innovative V8 engine features an electric-motor driven Variable Valve Timing with intelligence and Electrically controlled intake cam (VVT-iE).
A newly developed Hydrocarbon Adsorber and Catalyst (HCAC) system is linked to the two-way exhaust to help prevent hydrocarbons contained in the exhaust from being released into the atmosphere during cold start up when the catalysts are not up to temperature.
The LS 600h L is defined as a "full hybrid," capable of operating in electric-only mode or with a combination of the petrol engine and electric motor.
As with the RX and GS PERFORMANCEHYBRID models, the LS600hL’s “600” suffix refers not to the cubic capacity of the engine but, rather, a power output comparable to that of a conventional, 6.0-litre petrol engine, whilst the ‘h’ suffix indicates the presence of Lexus’ hybrid system.
The claimed combined fuel consumption figure is 9.3 litres/100km and CO2 emissions are 219g/km.
