The Cadillac XLR was a two-seat luxury roadster with a power retractable hardtop, built from 2003 to 2009 over a single generation. It was introduced at the 2003 Detroit auto show as a halo model for Cadillac, with styling inspired by the 1999 Evoq concept.

History of the Cadillac XLR

The XLR shared much of its construction with the C6 Chevrolet Corvette, which arrived a year later: the Y platform, hydroformed steel perimeter side rails, a folded steel backbone, tubular front and rear bulkheads, an aluminium windshield structure, magnesium steering-column mounts, aluminium and balsawood composite floorboards and composite bodywork. Its engine, bodywork, interior, suspension settings and folding roof were unique. Both cars were built at Bowling Green in Kentucky, with the XLR on a dedicated station beside the Corvette line, and the XLR entered production a year before the Corvette.

Equipment

The XLR was the first production Cadillac with radar-based adaptive cruise control and with seats that were both heated and cooled, and it was nominated for the North American Car of the Year award for 2004. It had Bulgari-designed instruments, a head-up display, adaptive Magnetic Ride Control suspension with magneto-rheological dampers, a rear-mounted transmission and near 50:50 weight distribution. Standard and optional equipment included a touchscreen navigation radio with XM satellite radio and voice control, a Bose premium system, HID headlamps, perforated leather seats with driver memory, polished alloy wheels and wood trim. The aluminium and magnesium roof, supplied by Magna Car Top Systems, opened in under 30 seconds and needed 2.1 metres of clearance, cutting boot space from 11.6 to 4.4 cubic feet.

XLR-V and the end

The XLR-V, part of the first-generation V-Series, was previewed in a Super Bowl commercial in February 2005 and shown at the New York auto show that year. It used the supercharged 4.4-litre Northstar of the STS-V in a slightly milder state of tune, with 443 hp and 414 lb-ft, a six-speed automatic, larger brakes from the Corvette Z51 and 19-inch wheels, reaching 60 mph in 4.6 seconds and a limited 155 mph. For 2009 the XLR gained a new front and rear fascia, chrome side vents and an Alcantara headliner. Production ended on 31 March 2009.
