Mercedes SLR McLaren generations
1 generation (2007–2009)
The 1st generation Mercedes SLR McLaren was offered from 2007 to 2009 exclusively as a roadster, with four modifications spanning 626 to 650 hp. Every version pairs a 5439 cc engine with an automatic gearbox and rear-wheel drive. The notable versions are the 5.4 AT (626 hp), accelerating to 100 km/h in 3.8 seconds, and the 5.4 AT (650 hp), which cuts that to 3.7 seconds. An earlier-listed 5.4 AT (650 hp) variant from 2003–2008 records 3.6 seconds and fuel consumption of 14.5 l/100km.
Which Mercedes SLR McLaren to buy
- 5.4 AT (650 hp) (1 generation): the most common choice, with 650 hp and 0–100 km/h in 3.7 seconds over the 2007–2009 run.
- 5.4 AT (650 hp) (1 generation): the most powerful configuration, reaching 100 km/h in 3.6 seconds from its 5439 cc engine.
- 5.4 AT (626 hp) (1 generation): the most economical of the lineup at 14.5 l/100km, while still delivering 626 hp and a 3.8-second sprint.
Buying used is simplified by the short 2007–2009 production window and a single generation: every car shares the same 5439 cc engine, automatic gearbox and rear-wheel drive, so the main decision is between the 626 hp and 650 hp states of tune rather than between structurally different model years.
Which Mercedes SLR McLaren to avoid
The numbers show no dominated version outright, but the Mercedes SLR McLaren 5.4 AT (626 hp) gives up 24 hp and 0.1 seconds to 100 km/h versus the 5.4 AT (650 hp) while posting the same 14.5 l/100km consumption. On the data alone, the 650 hp version offers more performance at no measured efficiency cost, so the 626 hp car only makes sense on other grounds than these figures.
