Although the word “hybrid car” can already be described as common in the vernacular, many do not yet know what exactly this term actually means and, above all, what types of hybrids there are. What are the respective advantages and disadvantages of the individual hybrid types??
It is particularly important to the manufacturer Lexus to present the hybrid as such and that is exactly why Lexus asked us to put together a small “Hybrid 1 × 1” with a focus on full hybrids.
The mild and plug-in hybrids
Let’s start with the so-called mild hybrids. These have a small electric motor, but cannot drive purely electrically. That is why 48-volt systems also belong to this category. Some engineers even attribute vehicles with a start-stop system to the mild hybrids. It goes without saying that mild hybrids do not have to be charged externally. Plug-in hybrids, on the other hand, have to be charged externally because they have a high-voltage battery. You can drive purely electrically and are, in layman’s terms, an electric car that also has an internal combustion engine.
The full hybrid in detail
With that we have already arrived at the full hybrids. In general, full hybrids are simply called “hybrids”. You can cover a short range purely electrically. As a rule, it is said that the electric drive of a full hybrid must be able to produce 20 kW per ton of vehicle weight in order to earn this title. So if a vehicle weighs 1.5 tons, the electric drive must have at least 30 kW of power. In order to achieve this, full hybrids also have a high-voltage battery. A big advantage is that such vehicles do not have to be charged externally. They are self-sufficient with the help of recuperation. A generator stores the kinetic energy that would otherwise explode as electricity in the high-voltage battery. This energy can then be used again later for (electrical) sailing or starting.
Driving with a full hybrid is partly purely electric, partly with a combustion engine or even with both at the same time and in combination. In general, every manufacturer and every model has its own philosophy of how a full hybrid should work. Accordingly, hybrids cannot be compared with one another in terms of their technical structure.
A real full hybrid: the Lexus CT 200 h F Sport
The Lexus CT 200h F-Sport also belongs to the full hybrid category. The small city runabout has a 1.8 l petrol engine with 99 hp and a 60 kW electric motor. This means it consumes a combined 4.4 liters per 100 km. So you notice: a hybrid uses comparatively little fuel and thus saves money. In addition, it is environmentally friendly, because in the city or in stop-and-go mode it is powered purely electrically, driving locally emission-free – and noiseless. The CT 200h F-Sport moves with a combined CO2 emission value of 101 g / km. The big advantage of a hybrid is definitely in the city – and countless hybrid taxi drivers have known that for years.
It is precisely because of its positive properties that Lexus has long relied on hybrid technology. In fact, every series from Lexus is therefore also available as a hybrid without exception. So there should really be something for everyone interested in hybrid.

The consumption values for the Lexus CT 200h F SPORT: Combined CO2 emissions: 101 g / km Urban CO2 emissions: 108 g / km CO2 emissions extra-urban: 93 g / km
Combined fuel consumption: 4.4 l / 100km Urban fuel consumption: 4.7 l / 100km Extra urban fuel consumption: 4.1 l / 100km
The stated values were determined according to the prescribed measuring method. These are the “NEDC CO2 values” in the sense of Art. 2 No. 1 Implementing Regulation (EU) 2017/1153. The fuel consumption values were calculated on the basis of these values. The information does not relate to a single vehicle and is not part of the offer, but serves solely for purposes of comparison between different vehicle types. The values vary depending on the selected optional equipment.
Further information on the official fuel consumption and the official specific CO₂ emissions of new passenger cars can be found in the “Guide to fuel consumption, CO2 emissions and power consumption of new passenger cars”, which is available at all sales outlets and at DAT Deutsche Automobil Treuhand GmbH (www .dat.de) is available free of charge.
