Distinguished by a higher hood line, the newer front fascia (developed as an improved crumple zone) was brought closer in line with the GMT800 full-size pickup trucks introduced for 1999; the model line also introduced a degree of parts commonality between the two model lines. The dashboard underwent a redesign; along with the addition of dual-stage airbags, the interior added multiplex wiring (adding increased functionality to the interior electrical system). The Express was offered with 60/40 split panel doors on the passenger-side of the vehicle; in a first (since the Corvair cargo van), an option was added for the driver-side to receive the same split panel doors; this option was limited to the standard-length body (requiring doors on both sides). The option for the driver-side split 60/40 panel doors was available through at least model year 2014. Since its 2003 model revision, the Express has seen incremental updates to the model line. For 2008, the Express passenger van received side-curtain airbags and standard stability control (introduced for 3500-series vans for 2005); the steering wheel, seats, and gauge cluster were also redesigned. For 2011, the dashboard received upgrades (including Bluetooth compatibility and a USB port). For 2013, higher-trim passenger vans received a optional navigation system, rearview camera, and parking assist system. For 2015, all radios became digitally-tuned and a 120-volt outlet was added to the dash. For 2018, the Express dropped sealed-beam headlights from all models, adopting the four composite headlamps of higher-trim passenger vans. For 2019, higher-trim passenger vans received lane departure warning systems and collision alert warning features. An All Wheel Drive (AWD) was offered as an option for the model years 2003-2014. The AWD models came exclusively with GM's 5.3L V8. For 2022, the optional CD player was discontinued. Entering its 26th year of production, the Chevrolet Express has now overtaken its third-generation G-series Chevrolet Van predecessor in production longevity. Although it is anticipated that GM will discontinue the Express/Savana and replace it with a plug-in battery electric vehicle for the 2026 model year, using GM's Ultium battery technology and possibly sharing a platform with the BrightDrop Zevo, GM instead may introduce an updated Express for the 2027 model year, retaining internal combustion engines. Model overview Chassis The Chevrolet Express uses the GM GMT600 chassis, developed exclusively for full-size vans. Derived loosely from the GMT400 chassis of the fourth-generation C/K trucks, the model line uses a full-length ladder
